# Strategy Specifications
## Deck Name And Archetype
Stiflenought is a Premodern mono-blue tempo-combo deck built around resolving `Phyrexian Dreadnought` and answering its enters-the-battlefield sacrifice trigger with `Stifle` or `Vision Charm`, then protecting the resulting 12/12 threat with stack interaction and card selection. The registered strategy tags are tempo and combo; runtime decisions should treat the deck as a compact two-card threat engine backed by permission, not as a pure draw-go control deck.

- Count validation: Main deck is 60 cards exactly: 17 `Island` plus 43 nonland spells. Sideboard is 15 cards exactly: 4 `Annul`, 1 `Brain Freeze`, 3 `Essence Flare`, 4 `Hydroblast`, 1 `Powder Keg`, and 2 `Tsabo's Web`.
- Format validation: Format is Premodern. Final tournament legality should still be checked against the specific event rules source before registration; this guide does not assume banned-list certainty beyond the user-provided deck context.
- Stock status: The deck is a recognizable Stiflenought shell with a focused mono-blue tempo-combo core. The singleton `Brain Freeze`, singleton `Flash of Insight`, singleton `Powder Keg`, and sideboard `Essence Flare` package make it a tuned/hybrid build rather than a generic stock list.
- Mana status: The mana base is intentionally narrow and stable: every land is `Island`, and every registered spell is blue or colorless. The main concern is quantity, not color access: 17 `Island` means opening hands and `Gush`/`Foil` decisions must respect the visible land count, land drops remaining, and whether returning or discarding `Island` would strand future `Counterspell`, `Impulse`, `Stifle`, or `Vision Charm` interaction.
- Role status: The default role is proactive tempo-combo when a protected `Phyrexian Dreadnought` line is available; otherwise the deck becomes a selection-heavy permission deck using `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, `Gush`, and `Flash of Insight` to assemble threat plus protection. `Brain Freeze` is a secondary or emergency win condition, not the default plan unless storm count, library sizes, and visible stack history make it legal and strategically credible.
- Engine status: `Phyrexian Dreadnought` should not be committed casually into its sacrifice trigger unless `Stifle` or `Vision Charm` is available as a legal response or the game state makes an unsupported Dreadnought line intentionally expendable. Card text check required for any runtime use of `Vision Charm` modes beyond the known Dreadnought-support role.
- Interaction status: `Counterspell`, `Foil`, `Stifle`, `Annul`, and `Hydroblast` are role-defining interaction after sideboarding, but the decision agent must choose only among legal actions exposed by the rules engine and visible stack objects. Do not assume an opposing card is counterable, red, artifact/enchantment-relevant, or trigger-based unless the action list and public information show it.
- Opponent info status: No opponent decklist, matchup label, or metagame target is supplied in this batch. Later matchup guidance should stay conditional on public archetype evidence and runtime visible cards; policy `Cards:` fields must use only registered Stiflenought cards unless an opposing card is explicitly prefixed as `opponent:` outside registered-card lists.
- Quality gate: This guide must preserve exact card names, avoid invented card text, and defer uncertain rules conclusions to the engine. The agent should prioritize legal actions first, visible board and stack state second, and this deck-specific plan third.

## Thesis
Stiflenought assembles a protected `Phyrexian Dreadnought` as early as the rules engine makes the line legal, then converts one or two clean attacks into a win while mono-blue permission prevents the opponent from undoing the tempo advantage. The core tactical question is not simply "can I cast `Phyrexian Dreadnought`;" it is "can I cast it, answer its trigger with `Stifle` or an applicable `Vision Charm` line, and still survive the opponent's visible or likely response window."

The deck wins by making a 12/12 `Phyrexian Dreadnought` matter immediately, using `Counterspell`, `Foil`, `Stifle`, and sometimes `Vision Charm` to defend either the setup turn or the attack step. When the Dreadnought line is missing, the deck uses `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, `Gush`, and `Flash of Insight` to sculpt toward threat plus protection rather than spending resources on low-impact exchanges. `Brain Freeze` is a secondary payoff for high-spell-count games or stalled boards; do not treat it as the primary plan unless visible storm count, library totals, and legal action text make it a credible kill or a necessary emergency line.

The deck is not trying to become a long-game control deck, a tap-out draw engine, or a fair creature deck. `Powder Keg` gives a reset button against some permanent swarms, and the draw package can win long games by card volume, but those lines are supports for a tempo-combo kill. Prioritize assembling `Phyrexian Dreadnought` plus `Stifle` or `Vision Charm`, preserving blue mana for stack fights, and using card selection to find the missing half or protection instead of chasing generic card advantage.

The deck should spend cards aggressively when a protected Dreadnought attack will decide the game, but it should hoard interaction when the opponent has visible mana, stack pressure, or battlefield pressure that can punish a fragile commitment. `Foil` and `Gush` create explosive turns, yet returning or discarding `Island` can strand `Counterspell`, `Impulse`, or a second response; every free-spell line must check the current land count, future land drops, and whether the chosen turn is the real commitment turn.

## Role Package
- Threats: `Phyrexian Dreadnought` is the only main-deck creature and the defining threat. Commit it when `Stifle` or `Vision Charm` is present as a legal follow-up or when visible circumstances justify sacrificing it; avoid naked deployment as a routine play because the deck has few independent ways to win through wasted Dreadnought copies.

- Payoffs: `Phyrexian Dreadnought` is both threat and payoff because it turns one protected setup exchange into a lethal clock. `Brain Freeze` is the alternate payoff for spell-dense turns, opposing low-library states, or games where Dreadnought combat is blocked by public board texture; verify storm count and target legality from the engine before choosing it as a kill.

- Engines: `Accumulated Knowledge` is the scalable card-volume engine, with later copies becoming more valuable after earlier copies resolve or enter graveyards. `Gush` is the burst-resource engine that can reload while holding mana open, but it taxes `Island` count and can make future double-blue interaction worse. `Flash of Insight` is the late selection/recursion-adjacent engine; card text check required for exact graveyard use, cost, and selection depth at runtime.

- Velocity: `Opt`, `Portent`, and `Impulse` are the primary setup tools for finding either `Phyrexian Dreadnought`, `Stifle`, `Vision Charm`, or protection. Use cheap velocity before committing unless waiting gives the opponent a clearly faster clock; prefer `Impulse` when deeper selection is needed and mana can still cover the critical response window.

- Interaction: `Counterspell` handles broad stack threats when double blue is available. `Stifle` is primarily the Dreadnought enabler, but it can also interact with opposing triggered or activated abilities when the legal action list exposes that opportunity. `Powder Keg` is the main-deck permanent-control tool; use it as battlefield management, not as a substitute for protecting the combo.

- Protection: `Foil`, `Counterspell`, `Stifle`, and `Vision Charm` protect the Dreadnought plan in different ways. `Foil` can defend a tap-out or low-mana turn, but its alternate cost is real card and land pressure; protect a decisive Dreadnought or survival-critical exchange before spending it on replaceable threats.

- Recursion: The deck has no broad creature or spell recursion package. Treat graveyard value as mostly `Accumulated Knowledge` scaling plus conditional `Flash of Insight` use; do not assume lost `Phyrexian Dreadnought`, `Stifle`, or `Vision Charm` copies can be recovered.

- Mana: `Island` is the entire mana base, so color is stable and quantity is fragile. Keep enough `Island` access for double-blue `Counterspell`, setup cantrips plus `Stifle` or `Vision Charm`, and post-`Gush` recovery; avoid lines that return multiple `Island` unless the current turn is decisive or the hand still functions afterward.

- Sideboard modules: `Annul` expands cheap interaction against artifact or enchantment strategies. `Hydroblast` is the red-matchup stack and permanent answer when legal text permits it. `Essence Flare` is a Dreadnought-adjacent damage-pressure module; card text check required for exact timing, target, and drawback before use. The extra `Brain Freeze` strengthens alternate-kill and high-spell-count plans. The extra `Powder Keg` increases battlefield control against low-cost permanents. `Tsabo's Web` is a utility-land pressure module; card text check required for exact affected lands and replacement/card-draw behavior at runtime.

## Primary Win Conditions
- `Phyrexian Dreadnought` plus `Stifle` is the primary kill line: assemble `Phyrexian Dreadnought`, cast it when the rules engine exposes its sacrifice trigger, and use `Stifle` on that trigger if legal. Prioritize this line when the hand already contains protection, when the opponent is tapped low, when life totals make a two-attack clock decisive, or when waiting lets visible pressure force bad `Foil` or `Gush` exchanges.

- `Phyrexian Dreadnought` plus `Vision Charm` is the second primary setup line: use `Vision Charm` only if the engine exposes a legal mode and target that preserves `Phyrexian Dreadnought` through its trigger. Treat this as a real combo line, not a shortcut; if the legal action text does not clearly show the relevant `Vision Charm` action, choose through normal reasoning and do not assume the interaction works.

- Protected Dreadnought combat is the deck's actual conversion step: after `Phyrexian Dreadnought` survives, preserve mana and cards for removal, bounce, artifact answers, tap effects, edicts, or combat tricks shown by legal actions and public mana. Use `Counterspell` for broad stack protection, `Foil` when the attack or survival window is decisive, and `Stifle` only if using it defensively is better than saving it for another Dreadnought setup.

- Cantrip sculpting is part of the win condition: use `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, `Gush`, and `Flash of Insight` to find exactly threat, enabler, or protection. Prioritize `Impulse` or deeper selection when missing a specific combo half; prioritize cheap `Opt` or `Portent` when you must keep mana open for `Stifle`, `Vision Charm`, `Counterspell`, or `Foil`.

- `Brain Freeze` is the alternate main-deck kill: choose it as a win condition only when visible storm count, target legality, and library totals make milling meaningful or lethal. It becomes more attractive after long stack fights involving `Gush`, `Foil`, cantrips, and opposing spells, especially when `Phyrexian Dreadnought` combat is blocked by public battlefield texture or repeated removal.

## Secondary Win Conditions
- A delayed Dreadnought is still pressure: if early protection is weak, wait until `Counterspell`, `Foil`, or redundant enablers make the setup turn resilient. A turn-four protected `Phyrexian Dreadnought` is often stronger than a turn-one copy exposed to every visible answer.

- `Powder Keg` can create the attack lane: use it to reduce creature swarms, cheap permanents, or blockers that make a Dreadnought race unsafe. Do not spend it automatically; check whether charging, holding, or cracking it now improves the next Dreadnought attack or prevents lethal damage.

- Card-volume wins support both payoffs: repeated `Accumulated Knowledge` and carefully timed `Gush` can overpower trading games by finding more counters, enablers, and the singleton `Brain Freeze`. Use this route when the opponent spends multiple resources on the first `Phyrexian Dreadnought` or when public board state gives enough time to draw into a second commitment.

- Defensive `Stifle` can become a tempo win: if the Dreadnought line is already assembled through `Vision Charm`, redundant `Stifle` may answer an opposing triggered or activated ability when the engine exposes that legal action. Spend it this way only when the tempo gained protects life total, stops a key answer, or opens a near-term Dreadnought kill.

- Fair non-Dreadnought damage is not a plan: the registered main deck has no backup creature package and no burn package. If `Phyrexian Dreadnought` is unavailable, move toward `Brain Freeze`, card selection, and survival rather than pretending the deck can win through incidental combat.

## Emergency Lines
- Behind on life: preserve interaction for survival-critical spells and combat steps before spending mana on speculative selection. `Powder Keg` can buy time against creature pressure, `Foil` can defend while tapped low, and `Gush` should be used only if returning `Island` does not expose you to dying before the next meaningful action.

- Behind on board: look for `Powder Keg`, protected `Phyrexian Dreadnought`, or a stack interaction that prevents the battlefield from becoming lethal. Do not fire cantrips purely for card quantity when a legal stabilizing action is available and visible attackers threaten a short clock.

- Behind on cards: lean on `Accumulated Knowledge`, `Gush`, `Impulse`, and `Flash of Insight` to rebuild, but avoid trading `Foil` for low-impact spells unless the exchange prevents lethal damage or protects a committed Dreadnought. A small hand with threat plus enabler can still win; a large hand without a payoff often cannot.

- Behind on mana: protect `Island` count and avoid alternate-cost `Gush` or `Foil` unless the current turn is decisive. Double blue for `Counterspell` matters, and single blue plus another action often matters; returning lands can convert a winnable hand into one that cannot answer the next stack window.

- Behind on engine or selection: use the cheapest legal cantrip that preserves the most future mana when searching for a missing combo piece. If the hand already has `Phyrexian Dreadnought` plus `Stifle` or `Vision Charm`, selection should usually find protection rather than more velocity.

- Facing graveyard pressure: do not overvalue graveyard-dependent scaling from `Accumulated Knowledge` or conditional `Flash of Insight`; card text check required for exact graveyard use of `Flash of Insight`. If graveyards are disrupted, shift toward immediate Dreadnought commitment or visible `Brain Freeze` math rather than relying on future recursion value.

- Facing combo or faster inevitability: commit earlier if waiting gives the opponent a clear public path to win, but still require a legal enabler for `Phyrexian Dreadnought` unless sacrificing it is tactically forced. Use `Counterspell`, `Foil`, and defensive `Stifle` to break the opponent's decisive turn, then convert with the fastest available payoff.

- If win conditions are removed: count remaining `Phyrexian Dreadnought` and `Brain Freeze` copies from public zones and known hand only. If all visible Dreadnought paths are gone, prioritize `Brain Freeze` storm setup and survival; if `Brain Freeze` is also unavailable, continue choosing legal survival and draw actions without inventing a concession or nonexistent alternate kill.

## Resource Model
- Life total is a timer, not a fuel source: spend life only by accepting damage while sculpting a protected `Phyrexian Dreadnought` or a real `Brain Freeze` window. If visible attackers create a short clock, shift from cantrip greed to survival actions such as `Counterspell`, `Foil`, `Powder Keg`, or a protected Dreadnought commitment.

- Hand size is the deck's protection budget: a hand with `Phyrexian Dreadnought`, `Stifle` or `Vision Charm`, and one protective card is often more valuable than a larger hand of cantrips. Preserve extra blue cards and `Island` for `Foil` only when the stack window is decisive; do not turn `Foil` into routine one-for-one interaction if `Counterspell` or patience can cover the same threat.

- Mana converts into timing flexibility: one untapped `Island` represents `Opt`, `Stifle`, `Vision Charm`, `Annul`, or `Hydroblast`; two untapped `Island` represents `Counterspell`, `Impulse`, `Accumulated Knowledge`, `Brain Freeze`, `Powder Keg`, `Essence Flare`, or `Tsabo's Web` depending on sideboard configuration. Protect double-blue availability before choosing a draw spell that taps low.

- Board presence is almost binary: the main deck usually has either no creature pressure or a surviving `Phyrexian Dreadnought`. Treat `Phyrexian Dreadnought` as the board conversion engine, and treat `Powder Keg` as the tool that buys time or clears low-cost blockers and pressure.

- Graveyard value matters but is not a promise: `Accumulated Knowledge` scales from copies in graveyards, and `Flash of Insight` may use graveyard/exile resources; card text check required for exact `Flash of Insight` graveyard and exile handling. If graveyard disruption is visible, prefer immediate Dreadnought pressure, live stack interaction, and non-graveyard card selection.

- Exile is normally a cost or aftermath zone, not a resource engine: track any exiled `Phyrexian Dreadnought`, `Brain Freeze`, `Stifle`, or `Vision Charm` because losing win conditions changes the route. Do not assume exiled cards are recoverable unless the rules engine exposes a legal action.

- Lands are both mana and alternate-cost material: `Gush` can turn `Island` into cards, and `Foil` can turn an `Island` plus a blue card into emergency permission. Returning or discarding `Island` is acceptable when protecting a win, preventing a loss, or setting up a decisive turn; it is costly when it breaks future `Counterspell` mana.

- Sacrifice fodder is effectively absent: the registered main deck does not contain expendable creatures for `Phyrexian Dreadnought`'s sacrifice trigger. Plan to neutralize the trigger with `Stifle` or a legal `Vision Charm` line, not to pay it through battlefield material.

- Tempo is the main exchange rate: a resolved `Phyrexian Dreadnought` can end the game quickly, so spending cards to protect it is often correct. Before committing, compare the opponent's visible clock, open mana, known answers, and your redundancy; waiting is better when protection is missing and the opponent is not forcing action.

- Information comes from cantrips and public zones: use `Portent`, `Opt`, `Impulse`, `Accumulated Knowledge`, `Gush`, and `Flash of Insight` to identify whether the missing piece is threat, enabler, protection, or alternate kill. Respect only visible cards, revealed information, legal actions, and public graveyard/exile counts.

- Sideboard bullets convert narrow mana into matchup leverage: `Annul` answers legal artifact or enchantment stack threats, `Hydroblast` fights red cards when legal, `Essence Flare` is creature-specific pressure or answer text requiring runtime legality, `Tsabo's Web` attacks land-function matchups, the extra `Powder Keg` improves board control, and the extra `Brain Freeze` raises alternate-kill density.

## Mana Guide
- Keep mana bases simple but strict: every land is `Island`, so color fixing is automatic and the real constraint is land count. Prioritize hands with at least one `Island` plus cheap selection, and prefer two `Island` when the hand needs `Counterspell`, `Impulse`, `Accumulated Knowledge`, `Brain Freeze`, `Powder Keg`, `Essence Flare`, or `Tsabo's Web`.

- Mulligan one-land hands without cheap selection or a complete fast plan: one `Island` plus `Phyrexian Dreadnought` and `Stifle` can be functional, especially with `Opt` or `Portent`, but one `Island` hands full of two-mana spells are fragile. Two `Island` plus selection and either threat, enabler, or protection is a strong baseline.

- Sequence `Island` every turn until future interaction is secure: missing the second land weakens `Counterspell`, and missing the third or fourth land makes hard-cast `Foil`, cast-plus-protect turns, and post-`Gush` rebuilding worse. Do not skip land drops to conceal information unless the legal line is already winning or hand-size pressure demands it.

- Play lands before draw spells when you need immediate mana expansion or must cast a found one-mana action this turn. Hold a land until after `Brainstorm`-like decisions only if such a legal action exists; this list has `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, `Gush`, and `Flash of Insight`, so normal default is to make land drops before routine selection.

- Cast one-mana selection to preserve interaction windows: `Opt`, `Portent`, `Stifle`, and `Vision Charm` all compete for the first `Island`. If holding up `Stifle` or `Vision Charm` is required for a pending `Phyrexian Dreadnought` line, delay speculative `Opt` or `Portent` unless the engine offers a timing window where the mana will refresh before commitment.

- Protect double blue before tapping out: `Counterspell` is the clean broad answer, while `Foil` is the emergency answer that costs cards or mana. If the opponent can present a decisive stack action, leave two `Island` untapped when possible instead of spending the turn on `Impulse`, `Accumulated Knowledge`, `Powder Keg`, or `Tsabo's Web`.

- Use `Gush` as a card burst only when returning two `Island` does not break the next required action. `Gush` is excellent before a decisive protected turn or during a stack-heavy `Brain Freeze` setup, but it is dangerous when it removes double-blue protection, delays hard-cast spells, or exposes a surviving `Phyrexian Dreadnought` to the next answer.

- Use `Foil` alternate cost for decisive windows: pitching an `Island` and a blue card is justified to protect `Phyrexian Dreadnought`, stop lethal pressure, or counter a spell that invalidates the current win path. Prefer normal mana payment or `Counterspell` for lower-impact exchanges.

- Treat colorless artifacts as timing costs: `Phyrexian Dreadnought` costs little mana but demands an enabler and protection; `Powder Keg` costs the turn's mana and future timing. Do not cast `Powder Keg` ahead of a near-term protected Dreadnought unless the visible battlefield makes stabilization more important.

- Sideboard mana remains mostly blue: `Annul` and `Hydroblast` reward keeping one `Island` open, while `Essence Flare`, `Tsabo's Web`, extra `Powder Keg`, and extra `Brain Freeze` reward reaching two mana. After sideboarding, decide whether the matchup asks for one-mana reactive posture or two-mana permanent/control posture before spending cantrip mana.

## Mulligan Guide
- Strong keep: keep `Island` plus `Island`, `Phyrexian Dreadnought`, `Stifle` or `Vision Charm`, and at least one of `Counterspell`, `Foil`, `Opt`, `Portent`, or `Impulse`. This hand has mana, combo access, and either protection or smoothing, so it can choose between fast pressure and a protected turn.

- Strong keep: keep one `Island`, `Phyrexian Dreadnought`, `Stifle`, and one-mana selection such as `Opt` or `Portent` when the hand has another blue card for `Foil` or a second enabler. This is riskier on the draw against discard or fast pressure, but it is a real turn-two threat plan if the second land appears.

- Medium keep: keep two `Island`, multiple selection spells, and interaction without `Phyrexian Dreadnought` when the hand includes `Impulse`, `Portent`, `Opt`, `Accumulated Knowledge`, or `Gush`. This hand should spend early turns finding the threat or enabler while preserving `Counterspell` or `Foil` for cards that punish durdling.

- Medium keep: keep `Phyrexian Dreadnought` plus `Vision Charm` without `Stifle` only when the hand has enough mana and protection to wait for the legal trigger window. Treat `Vision Charm` as combo-capable only when the rules engine exposes the correct action; do not assume undocumented mode timing.

- Risky keep: keep one `Island` with two-mana spells only when the hand has `Opt` or `Portent` and a clear payoff. One land plus `Counterspell`, `Impulse`, `Accumulated Knowledge`, `Powder Keg`, and no cheap selection is too likely to stall.

- Automatic ship: mulligan hands with zero `Island`, hands with only `Phyrexian Dreadnought` and no `Stifle` or `Vision Charm`, and hands with no selection, no interaction, and no combo path. Also ship hands that depend on hard-casting `Foil` while missing the land count to function.

- Matchup-dependent keep: keep slower `Counterspell`, `Foil`, `Powder Keg`, and selection hands against visible creature pressure or unknown fair decks if they can reach two mana. Against fast combo or heavy stack interaction, prioritize `Phyrexian Dreadnought` plus enabler plus protection over incremental `Accumulated Knowledge` value.

- Play/draw adjustment: on the play, value fast `Phyrexian Dreadnought` hands because a protected 12/12 can end the game before the opponent develops. On the draw, value `Foil`, `Counterspell`, `Opt`, and `Portent` more because the opponent gets the first chance to deploy discard, pressure, or removal.

- Trap hand: do not keep a hand because it contains `Brain Freeze`, `Gush`, and several cantrips unless it also has mana and interaction. `Brain Freeze` is an alternate finish or emergency route, not a reason to ignore the primary `Phyrexian Dreadnought` plan.

## Turn Arc
- Turn 1: lead `Island` and prefer `Portent` or `Opt` when the hand is missing either `Phyrexian Dreadnought`, `Stifle`, `Vision Charm`, or a second `Island`. If the hand already has a turn-two combo with protection, consider passing with `Stifle` or `Vision Charm` available only when the rules engine presents a relevant stack action.

- Turn 1 deviation: cast `Phyrexian Dreadnought` only if the legal trigger-answer line is available and strategically selected. Do not expose `Phyrexian Dreadnought` into its own sacrifice trigger without `Stifle`, legal `Vision Charm`, or a deliberate desperation reason.

- Turn 2: prefer a protected `Phyrexian Dreadnought` line when the hand has `Stifle` or legal `Vision Charm` and either `Foil`, `Counterspell`, or low visible risk. If the opponent represents decisive interaction, hold up `Counterspell` and use `Opt` at the latest safe point.

- Turn 2 deviation: deploy `Powder Keg` when the opponent has visible low-cost pressure that will race or block long enough to matter. Delay `Powder Keg` when the hand can make a protected `Phyrexian Dreadnought` immediately.

- Turn 3: prefer cast-plus-protect turns, such as `Phyrexian Dreadnought` with `Stifle` and `Foil`, or `Phyrexian Dreadnought` with enabler while leaving `Counterspell` available. If the combo is incomplete, cast `Impulse` or `Accumulated Knowledge` while preserving interaction when possible.

- Turns 4-5: convert resources into a decisive threat or alternate kill setup. Use `Gush` when it finds protection, adds storm count for `Brain Freeze`, or reloads after forcing through `Phyrexian Dreadnought`; avoid `Gush` when returning `Island` strands `Counterspell` or future `Impulse`.

- Turns 4-5 deviation: if `Phyrexian Dreadnought` is already attacking, spend cards to protect tempo rather than maximize draw value. `Foil` alternate cost is acceptable to stop a removal spell, bounce spell, lock piece, or lethal counterattack that the engine shows as legal.

- Late game: shift from pure tempo to redundancy management. Chain `Accumulated Knowledge`, `Impulse`, `Opt`, `Portent`, `Gush`, and `Flash of Insight` to find the missing threat, enabler, or protection, and track graveyards before valuing `Accumulated Knowledge` or `Flash of Insight`; card text check required for exact `Flash of Insight` graveyard use.

- Late game deviation: use `Brain Freeze` when storm count, library size, and legal target text make it a real win or survival line. Do not choose `Brain Freeze` over a protected `Phyrexian Dreadnought` attack unless the visible board or stack makes combat unreliable.

## Card Roles
- `Island`: Treat `Island` as the deck's main tempo resource, not just a land drop. Most functional hands need one early `Island`, but the strongest turns often need two untapped `Island` to combine `Phyrexian Dreadnought` plus `Stifle`, `Counterspell`, `Impulse`, or sideboard interaction. When `Gush` is legal, count the returned `Island` as a real tempo cost: returning lands can reload cards but may turn off `Counterspell`, delay `Impulse`, or make a protected `Phyrexian Dreadnought` turn weaker. Against mana denial or taxing effects, prefer land drops over fancy cantrip sequencing.

- `Phyrexian Dreadnought`: Use `Phyrexian Dreadnought` as the primary kill card and the deck's clearest commitment gate. Cast it only when `Stifle` or a legal `Vision Charm` line can answer its sacrifice trigger, or when the visible game state makes an unprotected attempt necessary. Protect a resolved `Phyrexian Dreadnought` over almost every incremental draw spell, because a 12/12 trampler shortens the game enough that card advantage often stops mattering. Do not run it into visible open interaction just because the mana is available; decide whether waiting adds protection, redundancy, or only gives the opponent time.

- `Stifle`: Reserve `Stifle` first for the `Phyrexian Dreadnought` trigger unless the opposing visible action is more decisive than creating or preserving the threat. It is the cleanest enabler because it spends one blue mana and does not require `Phyrexian Dreadnought` to remain on the battlefield through a separate target choice. Use `Stifle` defensively when the rules engine exposes a triggered or activated ability whose resolution would kill `Phyrexian Dreadnought`, break the mana base, win the game, or create an unrecoverable board. The common mistake is spending `Stifle` on a low-impact trigger, then drawing `Phyrexian Dreadnought` without an enabler.

- `Vision Charm`: Treat `Vision Charm` as both a combo enabler and a tactical trick, but only choose modes that the rules engine shows as legal. Its key `Phyrexian Dreadnought` use depends on phasing the artifact at the correct trigger window; do not assume the line exists unless Veles exposes the target/action. Its other modes can matter for lethal setup or disruption, but card text check required for exact mode text and matchup applications before relying on them. Hold `Vision Charm` when it is the only enabler; spend it more freely only when another `Stifle` or `Vision Charm` is available.

- `Counterspell`: Use `Counterspell` as the hard protection piece for the turn after committing `Phyrexian Dreadnought` or the turn that forces it through. It is better at stopping removal, bounce, lock pieces, sweepers, and opposing combo payoffs than at trading with routine creatures. Leave two blue mana open when the visible board suggests the opponent can answer `Phyrexian Dreadnought` immediately. Against creature decks, counter the card that changes the race or disables the 12/12; against control or combo, preserve it for stack fights around the decisive threat, not for marginal cantrips.

- `Foil`: Use `Foil` as the deck's emergency shield and as the reason some low-land, high-blue hands can still force a threat. The alternate-cost mode is card-expensive, so use it when the spell or ability being answered would remove `Phyrexian Dreadnought`, stop the combo, win the game, or put the pilot too far behind to recover. Hard-casting `Foil` is a late-game option, not a mulligan plan. Be careful with `Gush`: returning `Island` can supply cards but can also make `Foil` alternate cost or hard-cast timing awkward depending on the hand.

- `Gush`: Cast `Gush` when the extra cards are worth the land reset: finding `Stifle`, `Vision Charm`, `Phyrexian Dreadnought`, `Counterspell`, or `Foil`; rebuilding after a fight; or increasing spell count for a credible `Brain Freeze`. Delay `Gush` when returning `Island` turns off immediate protection or delays a two-mana interaction turn. Against fast pressure, `Gush` is good only if it finds a stabilizing line quickly; against slower decks, it is one of the best ways to reload while holding up free protection.

- `Accumulated Knowledge`: Use `Accumulated Knowledge` as scalable card advantage after the deck has stabilized or when the missing piece is not urgent enough to require `Impulse`. The first copy is often modest, but later copies can overpower fair interaction and refill after `Foil`. Track graveyards because opposing or prior copies can change its value; do not assume a fixed card count without visible confirmation. Against fast decks, casting it early may be too slow unless the hand already has interaction or a near-term `Phyrexian Dreadnought` plan.

- `Impulse`: Use `Impulse` as the best two-mana selection spell for assembling the exact missing category: threat, enabler, protection, or land. Cast it at the opponent's end step when holding up `Counterspell` matters, but main-phase it when the choice affects the current turn's legal actions. Do not take a generic draw spell over the missing combo piece unless the visible board says the game will go long. After sideboard, `Impulse` becomes especially important for finding narrow cards without overboarding into clunky hands.

- `Opt`: Use `Opt` to smooth one-land hands, hold up interaction, and make end-step progress without committing mana on the pilot's main phase. It is weaker than `Impulse` for finding a specific missing card, but stronger for preserving a reactive posture. Cast it before a critical draw only when the scry decision meaningfully changes the next action; otherwise keep mana open until the latest safe point. Do not burn `Opt` during a stack fight unless finding `Foil`, `Counterspell`, `Stifle`, or another exposed legal answer can matter immediately.

- `Portent`: Use `Portent` as early setup when the hand needs land, `Phyrexian Dreadnought`, `Stifle`, or `Vision Charm`. Its delayed draw timing means it is strongest on turn one and weaker when an immediate answer is needed. Targeting decisions should respect visible information and legal text; card text check required for exact opponent-target use in tactical denial lines. Do not choose a fancy manipulation line when the simple plan is finding the missing combo category.

- `Brain Freeze`: Treat main-deck `Brain Freeze` as an alternate win condition and emergency route, not the default plan. It becomes real when several spells have been cast in the turn, the opponent's library count is low enough, or `Gush`, `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, and counter fights create enough storm. Do not fire it because it is available; check target legality, storm count, library size, and whether the opponent can still win before decking matters. It can also punish long control exchanges, but `Phyrexian Dreadnought` remains the cleaner clock when protected.

- `Flash of Insight`: Use `Flash of Insight` as a late-game precision finder when mana and graveyard resources make a large selection spell better than chaining small cantrips. Card text check required for exact flashback cost and exile requirements, so runtime choices should verify legal action text before treating graveyard use as available. It is poor in early tempo hands because it asks for mana before affecting the board. Value it higher in grindy games where the pilot needs a specific `Phyrexian Dreadnought`, `Stifle`, `Vision Charm`, `Counterspell`, or `Brain Freeze` line.

- `Powder Keg`: Use `Powder Keg` as the main-deck reset valve against cheap permanents that race, swarm, or invalidate a single `Phyrexian Dreadnought`. It is slow and timing-sensitive, so deploy it when the visible battlefield requires containment more than immediate combo pressure. Be careful not to set it up in a way that threatens the pilot's own `Phyrexian Dreadnought` unless that trade is intentionally forced by survival. Against control or combo with few relevant permanents, it is often a low-priority card compared with selection and countermagic.

## Interaction Priorities
- Priority: Protect a resolved `Phyrexian Dreadnought` before fighting over marginal development spells. Once the 12/12 is legal and on the battlefield, spend `Counterspell`, `Foil`, `Stifle`, or `Vision Charm` on the opposing answer that would remove, neutralize, tap down, bounce, phase, steal, or otherwise invalidate it before damage matters.

- Priority: Counter the spell that changes the clock, not the first spell cast. Against fast creature decks, save `Counterspell` and `Foil` for a swarm payoff, burn spell that creates lethal, removal aimed at `Phyrexian Dreadnought`, or a permanent that makes racing impossible. Against control, counter card advantage or answers only when they matter to a protected `Phyrexian Dreadnought` turn; do not trade hard counters for low-impact filtering unless the hand is flooded with interaction and missing nothing.

- Priority: Use `Stifle` primarily as a combo enabler unless a visible triggered or activated ability will decide the game. The default use is answering the `Phyrexian Dreadnought` sacrifice trigger when Veles exposes that legal action; spend `Stifle` defensively only when the opposing ability would remove the Dreadnought, create lethal, stop the pilot from executing the combo, or generate an irreversible board swing.

- Priority: Use `Vision Charm` as the second main enabler and as conditional protection only when legal action text supports the mode. If the pilot controls `Phyrexian Dreadnought` and Veles exposes a target/action that can protect or enable it, prefer that line over spending `Vision Charm` for speculative disruption. Card text check required for exact non-Dreadnought modes, so do not rely on land-type or library-use lines unless the runtime action is explicit.

- Priority: Use `Powder Keg` to remove cheap permanents that beat the `Phyrexian Dreadnought` plan or flood the board faster than a two-turn clock. Build counters toward the visible mana value that matters most, but avoid lines that threaten the pilot's own `Phyrexian Dreadnought` unless survival requires that exchange. Ignore isolated small creatures when the Dreadnought clock is protected and lethal is close.

- Bait: Use `Opt`, `Portent`, first-copy `Accumulated Knowledge`, and sometimes `Impulse` to draw out soft permission or reveal the opponent's response posture before committing `Phyrexian Dreadnought`. Do not bait with the only `Stifle`, only `Vision Charm`, or only `Phyrexian Dreadnought` unless the hand cannot win by waiting.

- Ignore: Let routine creatures, cantrips, and slow value spells resolve when the pilot has a protected two-turn `Phyrexian Dreadnought` race. Fight over them only when life total, board size, or visible follow-up actions show that the opponent can race, lock combat, or force the pilot to spend all protection before the decisive turn.

- Constraint: This main deck has no discard, exile, or bounce package. If Veles exposes discard, exile, or bounce actions, treat them as side-effect or opponent-controlled actions and verify card text before choosing them; do not invent those roles for `Counterspell`, `Foil`, `Stifle`, `Vision Charm`, or `Powder Keg`.

- Archetype shift: Against aggro, interaction prioritizes survival until `Phyrexian Dreadnought` attacks safely. Against control, interaction prioritizes resolving and protecting one threat through a stack fight. Against combo, interaction prioritizes stopping the payoff or engine turn, then winning quickly with Dreadnought or a high-storm `Brain Freeze` only when visible storm and library counts justify it.

## Combat And Trading Rules
- Attack: Attack with `Phyrexian Dreadnought` whenever it is untapped, legal to attack, and the visible board does not show a lethal crack-back or a known combat answer. A 12/12 usually ends the game in two attacks, so do not hold it back to preserve life unless the opponent's next attack is lethal or a block is the only survival line.

- Block: Block with `Phyrexian Dreadnought` only when blocking prevents lethal, preserves a clearly winning race, or forces the opponent to spend multiple visible resources. Avoid casual trades or damage-soak blocks that expose the only win condition to combat tricks, tap effects, or post-combat removal when attacking next turn would be decisive.

- Protection: Hold blue mana or `Foil` resources through combat when the opponent can interact at instant speed. If attacking with `Phyrexian Dreadnought` and the pilot has `Counterspell`, avoid tapping the second `Island` for nonessential `Opt`, `Portent`, `Accumulated Knowledge`, or `Impulse` before combat unless the legal action directly finds missing protection.

- Engine preservation: Preserve `Phyrexian Dreadnought` over card quantity once it is active. Spending `Foil` plus a blue card and an `Island` can be correct if the protected attack puts the opponent under immediate lethal pressure; it is poor if the Dreadnought is not yet threatening lethal and the hand has no rebuild path.

- Life thresholds: Treat 12 or less opposing life as a one-hit Dreadnought game if no prevention or blocker is visible. Treat the pilot's life total as urgent when the opponent's visible battlefield can present lethal next turn; in that case, `Powder Keg`, defensive `Counterspell`, and blocking become more important than extra selection.

- Race math: Prefer the line that makes the opponent answer `Phyrexian Dreadnought` immediately. If the opponent must leave back blockers that cannot profitably block a 12/12, attack and keep protection. If the opponent can race with flyers, burn, or a wide board, prioritize removing or countering the card that changes the clock instead of drawing extra cards.

- Small creatures: Do not trade resources for small attackers when `Phyrexian Dreadnought` will close the game first. Use `Powder Keg` or counters against a mass of cheap threats only when the damage race beats the Dreadnought plan or when the pilot has not assembled the combo.

- Archetype difference: Against aggro, block or reset only when necessary to survive until the Dreadnought attack sequence. Against control, combat is mostly about forcing the opponent to answer one protected threat. Against combo, combat pressure is interaction because a two-turn clock reduces how long the opponent has to assemble a payoff.

## Selection And Tutor Rules
- Selection: This deck has no true tutor, so treat `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, `Gush`, and `Flash of Insight` as pseudo-tutors for the missing half of `Phyrexian Dreadnought` plus `Stifle` or `Vision Charm`. Prioritize finding the missing combo card first, then protection, then extra card volume.

- Missing threat: When the hand has `Stifle` or `Vision Charm` but no `Phyrexian Dreadnought`, use `Impulse` as the highest-quality dig spell because it sees the most cards immediately. Use `Portent` and `Opt` to smooth toward the threat, but do not bottom an enabler unless the hand already has redundant enablers and needs a threat, land, or counter.

- Missing enabler: When the hand has `Phyrexian Dreadnought` but no `Stifle` or `Vision Charm`, keep any visible enabler from selection even over generic protection. A protected Dreadnought turn is ideal, but an unenabled Dreadnought is not a threat.

- Missing land: Prioritize `Island` until the hand can cast cantrips and hold up relevant interaction. Two `Island` is the key baseline because it supports `Counterspell`, normal `Impulse`, and flexible combo turns; extra lands beyond that matter mainly for casting spells while preserving `Counterspell` mana or paying for `Flash of Insight`.

- Land timing: Delay the land drop when resolving `Portent`, `Opt`, `Impulse`, or `Gush` before the land play and the hand may need the new information. Make the land drop before passing when holding `Counterspell` or representing interaction matters more than concealing information.

- Gush: Use `Gush` as card velocity when returning two `Island` will not strand `Counterspell`, delay a required combo turn, or expose the pilot to a lethal tempo loss. Prefer alternate-cost `Gush` when the hand needs blue cards for `Foil`, storm count for `Brain Freeze`, or a burst of cards before a decisive stack fight.

- Accumulated Knowledge: Cast early `Accumulated Knowledge` when the hand needs raw material, but value later copies more highly once one or more copies are in graveyards. If both players have visible `Accumulated Knowledge` in graveyards, count all graveyard copies when estimating draw size and do not assume only the pilot's graveyard matters.

- Flash of Insight: Use `Flash of Insight` as a mana-scaled dig spell when the game has reached a slower stack posture or the pilot needs a specific missing card. Card text check required for exact flashback cost handling at runtime; if Veles exposes a flashback action, preserve critical blue cards unless the flashback finds or protects the winning line.

- Brain Freeze: Treat main-deck `Brain Freeze` as a secondary finisher or emergency self/targeted library interaction only when visible storm count and library counts support the line. Do not spend selection looking for `Brain Freeze` ahead of the Dreadnought package unless the opponent's board or answers make combat unrealistic.

## Priority And Stack Rules
- Combo trigger: When `Phyrexian Dreadnought` enters and Veles exposes its sacrifice trigger, respond with `Stifle` or the legal `Vision Charm` line that preserves Dreadnought if available. Do not pass that trigger expecting the rules engine to save the creature unless a legal action explicitly does so.

- Protection window: After committing `Phyrexian Dreadnought`, keep priority discipline around removal, bounce, tap effects, sacrifice effects, and opposing stack interaction. Use `Counterspell` or `Foil` on the answer that would remove or neutralize Dreadnought, not on unrelated spells that leave the two-turn clock intact.

- Counter hierarchy: Use `Counterspell` when two untapped `Island` are available and preserving cards matters; use `Foil` when tapped out, when protecting an immediate win, or when the spell being answered is more important than the card and `Island` loss. Do not pitch the only remaining enabler, threat, or recovery spell to `Foil` unless the current stack exchange decides the game.

- Stifle discipline: Reserve `Stifle` for `Phyrexian Dreadnought` unless a visible activated or triggered ability is immediately decisive. Counter an opposing ability only when it creates lethal, stops the combo, removes Dreadnought, or produces an irreversible swing that the pilot cannot race.

- Vision Charm discipline: Use `Vision Charm` at instant speed for Dreadnought preservation when Veles exposes that target or mode. Card text check required for non-Dreadnought modes, so choose land-type, artifact phase, or mill actions only when the legal action text and visible state make the intended result explicit.

- Cantrip timing: Cast `Opt` on the opponent's end step when holding interaction matters, but cast it main phase when the pilot must find land, `Phyrexian Dreadnought`, `Stifle`, or `Vision Charm` before acting. `Portent` is sorcery-speed, so use it before committing to a land drop or combo line when its reorder/draw timing can shape the next turn.

- Let resolve: Let low-impact creatures, cantrips, and setup spells resolve when the pilot has a protected Dreadnought clock or needs counters for a payoff. Fight over spells that change lethal math, answer Dreadnought, deny the pilot's mana, or create a faster opposing kill.

- Powder Keg timing: Add counters to `Powder Keg` toward the visible permanent cost that matters, then activate only when the exchange improves survival or clears a blocker/lock piece. Avoid activating at a value that destroys the pilot's own `Phyrexian Dreadnought` unless that is the only survival line.

- Brain Freeze stack: Cast `Brain Freeze` only after visible spell count makes the target meaningful. Target the opponent when it can win or materially shrink their library; target self only if a legal, visible plan specifically benefits from self-mill and does not undermine the Dreadnought plan.

- Combat windows: Preserve instant-speed interaction through declare attackers, declare blockers, and pre-damage windows when the opponent can remove or neutralize `Phyrexian Dreadnought`. Spend selection in those windows only when finding protection is more important than representing existing protection.

## Sideboard Map
- Annul: Add `Annul` against artifact or enchantment engines that either answer `Phyrexian Dreadnought`, lock mana, or create a faster noncreature plan than the Dreadnought clock. Its role is cheap stack coverage that lets the deck commit `Phyrexian Dreadnought` while still protecting the combo at one mana.

- Annul when bad: De-emphasize `Annul` against creature-heavy decks with few visible artifact or enchantment payoffs. A one-mana counter is still efficient, but dead reactive cards are costly in hands that need `Island`, `Phyrexian Dreadnought`, `Stifle` or `Vision Charm`, and protection.

- Brain Freeze: Add the sideboard `Brain Freeze` when the opponent overloads on creature removal, fog effects, lock pieces, or blockers that make combat damage unreliable. Its role changes the deck from pure Dreadnought tempo into a mixed threat deck where long stack exchanges, `Gush`, `Foil`, cantrips, and repeated `Accumulated Knowledge` can create a real storm finish.

- Brain Freeze when bad: Reduce emphasis on extra `Brain Freeze` against fast creature pressure unless the matchup commonly creates long stack fights. Two copies can make opening hands less stable because they do not enable `Phyrexian Dreadnought`, answer a threat, or protect the first combo attempt.

- Essence Flare: Add `Essence Flare` against creature decks where a resolved `Phyrexian Dreadnought` needs help converting attacks through racing pressure or where a smaller creature can matter temporarily. Card text check required for exact timing and creature-risk handling; use it only when Veles exposes a legal target and the visible race rewards the commitment.

- Essence Flare when bad: De-emphasize `Essence Flare` against removal-heavy control and decks with many instant-speed answers, because investing another card into a creature increases exposure. It is also poor when the opponent can ignore combat and win through a stack, graveyard, or lock plan.

- Hydroblast: Add `Hydroblast` against red removal, red burn, red sweepers, and red creature tempo. Its role is premium one-mana protection for `Phyrexian Dreadnought` and a survival spell against direct damage races; keep blue card count and mana posture in mind before spending `Foil` over `Hydroblast`.

- Hydroblast when bad: De-emphasize `Hydroblast` when the opponent has few or no red spells visible across the match. Do not keep reactive hands because they contain `Hydroblast`; the hand still needs a combo path, card selection, or enough interaction that can legally answer the opponent's actual colors.

- Powder Keg: Add the sideboard `Powder Keg` against low-cost permanent swarms, artifact creatures, token pressure, or hate permanents clustered at the same mana value. Its role is board reset and tempo recovery; manage counters so it does not destroy the pilot's own `Phyrexian Dreadnought` unless survival requires it.

- Powder Keg when bad: De-emphasize extra `Powder Keg` against slow spell-heavy decks, combo decks with few permanents, or matchups where the important opposing cards have scattered mana values. It is slow when the pilot needs to protect a fast Dreadnought or hold stack interaction every turn.

- Tsabo's Web: Add `Tsabo's Web` against mana bases with important nonbasic activated abilities or decks whose lands create inevitability. Its role is tempo disruption that can buy Dreadnought attack steps while replacing itself; Card text check required for exact affected-land rules, so rely on visible legal actions and public board texture.

- Tsabo's Web when bad: De-emphasize `Tsabo's Web` against mostly basic mana, fast red pressure, and decks where the decisive cards are cheap spells rather than lands. It should not crowd hands that need the two-card Dreadnought package and stack protection.

Artifact-Enchantment Engine Plan
Side in: 4 Annul; 1 Powder Keg; 2 Tsabo's Web
Cut: 3 Vision Charm; 1 Brain Freeze; 1 Flash of Insight; 2 Portent

- Plan use: Use this balanced plan when the opponent presents artifact or enchantment engines plus meaningful nonbasic land utility. `Annul` protects the stack, `Powder Keg` answers resolved low-cost permanents, and `Tsabo's Web` pressures mana development while the deck assembles `Phyrexian Dreadnought` plus `Stifle`.

Red Pressure Plan
Side in: 4 Hydroblast; 3 Essence Flare
Cut: 1 Brain Freeze; 1 Flash of Insight; 1 Powder Keg; 2 Accumulated Knowledge; 2 Portent

- Plan use: Use this balanced plan when red damage and red removal define the matchup. `Hydroblast` is the priority addition because it protects `Phyrexian Dreadnought` and buys life-total time; `Essence Flare` is conditional race support when a visible creature can safely become the decisive clock.

Creature Swarm Plan
Side in: 1 Powder Keg; 3 Essence Flare
Cut: 1 Brain Freeze; 1 Flash of Insight; 2 Foil

- Plan use: Use this balanced plan against creature-heavy decks where the game is decided by board presence and combat speed rather than stack density. The extra `Powder Keg` gives a recovery line, while `Essence Flare` can change race math when a legal target is already present and removal exposure is acceptable.

Slow Control And Attrition Plan
Side in: 1 Brain Freeze; 2 Tsabo's Web
Cut: 1 Powder Keg; 2 Vision Charm

- Plan use: Use this balanced plan when the opponent slows combat with removal, mana development, or long-game inevitability. The second `Brain Freeze` gives a noncombat endgame after stack fights, while `Tsabo's Web` can tax land-based resources without weakening the core `Phyrexian Dreadnought` plus `Stifle` plan too much.

- Broad artifact/enchantment rule: Add role cards: `Annul`, sideboard `Powder Keg`, and sometimes `Tsabo's Web`. Reduce main-deck emphasis: slower selection and fragile nonessential enabler density, while preserving enough `Stifle` or `Vision Charm` effects to execute `Phyrexian Dreadnought`.

- Broad red rule: Add role cards: `Hydroblast` first, then `Essence Flare` only when combat racing matters. Reduce main-deck emphasis: slow draw and expensive recovery cards, because survival and one-mana protection matter more than sculpting an ideal long game.

- Broad creature rule: Add role cards: sideboard `Powder Keg` and selective `Essence Flare`. Reduce main-deck emphasis: expensive reactive cards that do not affect combat, especially when the opponent can force a short clock before `Accumulated Knowledge` becomes large.

- Broad control rule: Add role cards: sideboard `Brain Freeze`, `Tsabo's Web`, and narrow `Annul` only if public information shows artifact or enchantment targets. Reduce main-deck emphasis: creature-only race cards and redundant board reset effects, because the important decisions are threat timing, counter fights, and alternate win pressure.

- Broad combo rule: Add role cards only when they interact with the opponent's visible engine: `Annul` for artifact or enchantment combo pieces, `Hydroblast` for red combo components, and `Brain Freeze` for long stack races. Reduce main-deck emphasis: `Powder Keg` and `Essence Flare` when the opponent is not trying to win through creatures or permanents that those cards can affect.

- Post-sideboard role change: Play more patiently when added answers increase protection density, but do not abandon the core tempo plan. `Phyrexian Dreadnought` backed by `Counterspell`, `Foil`, `Hydroblast`, or `Annul` remains the cleanest win; sideboard cards are there to clear the matchup's obstacle, not to turn the deck into hard control.

- Runtime legality rule: Follow Veles legal actions before sideboard intent. If a sideboard card's text, target, color restriction, or timing is uncertain, choose it only when the rules engine exposes the legal action and visible state matches the planned role.

## Matchup Guidance

- Aggro: Prioritize a fast `Phyrexian Dreadnought` backed by `Stifle` or `Vision Charm` when the opponent's visible board threatens a short clock. Keep hands that can produce early pressure plus at least one interaction piece; `Counterspell` and `Foil` protect the first decisive threat, while `Opt`, `Portent`, and `Impulse` should find missing combo pieces rather than chase long-game value. Add role cards: `Hydroblast` against red pressure, `Essence Flare` when racing through combat is realistic, and sideboard `Powder Keg` when low-cost permanents cluster. Reduce main-deck emphasis: slow graveyard-sized `Accumulated Knowledge` plans and noncombat finishers when survival is the bottleneck.

- Control: Force the opponent to answer threat timing rather than letting them sculpt a perfect late game. Lead with selection until `Phyrexian Dreadnought` can be deployed with `Counterspell`, `Foil`, `Hydroblast`, or `Annul` support, and use `Gush` carefully because returning `Island` can weaken protection on the commitment turn. `Accumulated Knowledge` improves as the game lengthens, and the sideboard `Brain Freeze` can matter when stack exchanges build spell count or combat becomes unreliable. Add role cards: `Brain Freeze`, `Tsabo's Web`, and conditional `Annul` when public information shows artifacts or enchantments. Reduce main-deck emphasis: `Powder Keg` and fragile combat-only enhancements.

- Combo: Treat the matchup as a race with selective stack interruption, not as a generic value game. `Counterspell`, `Foil`, and matchup-relevant `Annul` or `Hydroblast` should be saved for engine pieces, payoff spells, or protection spells that the rules engine exposes as legal targets; do not spend them on low-impact setup unless the visible clock demands it. `Phyrexian Dreadnought` is the cleanest pressure because it reduces the number of turns the opponent has to assemble. Add role cards: `Annul` for artifact or enchantment engines, `Hydroblast` for red spell engines, and sideboard `Brain Freeze` for long stack games. Reduce main-deck emphasis: `Powder Keg` and `Essence Flare` unless creatures or relevant permanents are visible.

- Tempo: Fight over mana efficiency and threat windows, because both players can punish tap-out turns. Use `Opt`, `Portent`, and `Impulse` to make land drops, find `Stifle` or `Vision Charm`, and avoid exposing `Phyrexian Dreadnought` into open interaction without protection when waiting preserves the same clock. `Foil` is powerful when it protects a decisive Dreadnought while tapped low, but discarding cards can damage follow-up play, so prefer `Counterspell` when mana is available. Add role cards: `Hydroblast` against red tempo and `Annul` against artifact or enchantment threats. Reduce main-deck emphasis: expensive recovery lines when the opponent is pressuring both life total and stack.

- Midrange: Lean into the tempo-combo identity before the opponent's removal and card advantage can trade profitably. A protected `Phyrexian Dreadnought` can invalidate creature boards, but removal-heavy visible posture means the first Dreadnought should usually wait for `Counterspell`, `Foil`, or relevant sideboard protection. `Accumulated Knowledge`, `Gush`, and `Flash of Insight` matter when the game slows and both players trade resources; use them to reload rather than to delay a protected kill. Add role cards: `Essence Flare` only when a creature race is present, `Powder Keg` when board clutter matters, and `Annul` only for shown artifact or enchantment pressure. Reduce main-deck emphasis: narrow noncombat plans if the opponent is vulnerable to a single protected threat.

- Big mana: Pressure early and disrupt the specific mana or payoff axis visible on board. `Phyrexian Dreadnought` is the preferred clock because big-mana decks often become favored if given many turns; `Counterspell` and `Foil` should answer payoff spells or mana engines rather than incidental setup. `Tsabo's Web` can buy turns against nonbasic land abilities when the rules engine and public board make that role relevant; Card text check required for exact affected-land rules. Add role cards: `Tsabo's Web`, conditional `Annul`, and sideboard `Brain Freeze` if the game is expected to go long. Reduce main-deck emphasis: `Powder Keg` unless low-cost permanents matter.

- Graveyard: Keep the plan proactive unless the opponent's graveyard is the actual engine. This registered deck has no dedicated graveyard hate, so the best response is often to shorten the game with `Phyrexian Dreadnought` and hold `Counterspell` or `Foil` for payoff actions that the rules engine exposes. `Brain Freeze` can be dangerous if it fuels the opponent's graveyard, so choose it only when it is a real win path or the opponent cannot convert milled cards. Add role cards: `Annul` or `Hydroblast` only if the graveyard engine uses matching visible card types or colors. Reduce main-deck emphasis: slow self-contained draw if the opponent's graveyard kill is faster.

- Artifact/enchantment: Respect resolved permanents that blank the Dreadnought plan or create inevitability. `Annul` is the cleanest sideboard role card for stack-level prevention, while `Powder Keg` can answer low-cost resolved permanents if its counters line up with visible mana values. `Vision Charm` has artifact-related text, but Card text check required before relying on a specific artifact interaction beyond rules-engine legal actions. Add role cards: `Annul`, sideboard `Powder Keg`, and sometimes `Tsabo's Web` when lands are part of the engine. Reduce main-deck emphasis: nonessential slow selection while preserving enough `Stifle` and `Vision Charm` density for `Phyrexian Dreadnought`.

- Go-wide: Stabilize the board or end the game before small creatures make racing impossible. `Phyrexian Dreadnought` blocks and attacks through many boards, but it still needs protection from removal and bounce; do not spend `Foil` casually if it is the only protection for a lethal swing. `Powder Keg` is important when many threats share a low mana value, and `Essence Flare` can shift combat math when a legal target is already on board and removal exposure is acceptable. Add role cards: sideboard `Powder Keg` and selective `Essence Flare`. Reduce main-deck emphasis: long `Accumulated Knowledge` value lines under immediate combat pressure.

- Single-threat: Make the opponent's one threat irrelevant by racing or countering the threat that matters. `Phyrexian Dreadnought` usually wins a damage race against one creature if it survives, so stack protection should focus on removal, evasion enablers, or the threat itself when that is the only path to losing. `Powder Keg` is slower here unless the threat's mana value and timing make it a reliable answer. Add role cards: `Hydroblast` for red threats, `Annul` for artifact or enchantment threats, and `Tsabo's Web` for land-based single-threat engines. Reduce main-deck emphasis: swarm answers when only one permanent matters.

- Burn: Treat life total as a scarce resource and do not spend turns on slow sculpting if a protected two-turn clock is available. `Hydroblast` is premium because it can interact cheaply with red damage or red answers to `Phyrexian Dreadnought`; `Foil` can save mana but the card cost is real when every draw step matters. `Gush` should be used with care because returning `Island` can delay `Counterspell` or a protected Dreadnought turn. Add role cards: `Hydroblast` first and `Essence Flare` only for concrete race math. Reduce main-deck emphasis: `Brain Freeze`, `Flash of Insight`, and slow card-advantage posture.

- Removal-heavy: Wait for a protected commitment unless waiting clearly gives the opponent inevitability. `Phyrexian Dreadnought` asks for a second card to function, so losing it to an exposed removal spell is especially costly; prefer commitment turns with `Counterspell`, `Foil`, `Hydroblast`, or relevant `Annul` available. Use `Opt`, `Portent`, `Impulse`, `Accumulated Knowledge`, and `Gush` to rebuild without overcommitting, and consider `Brain Freeze` as a secondary route when combat is repeatedly answered. Add role cards: protection matching the opponent's colors and permanent types. Reduce main-deck emphasis: `Essence Flare` unless the legal target can end the race immediately.

## Specific Matchup Notes

- General note: These notes are archetype-only because no exact opposing decklist is supplied; revealed cards, legal actions, and public board state override all assumptions. Treat sideboard guidance as role weighting, not an executable plan, and choose actions only from the rules engine's current legal list.

- Red aggro or burn: Commit to `Phyrexian Dreadnought` faster when protection is available because the life-total race shrinks every turn. Add role cards: `Hydroblast` and conditional `Essence Flare` when combat math makes a legal creature target matter. Priority targets: red removal pointed at `Phyrexian Dreadnought`, red direct damage that changes the race, and haste or evasion threats that shorten the clock. Reduce main-deck emphasis: `Brain Freeze`, `Flash of Insight`, and slow `Accumulated Knowledge` setups when life total is under immediate pressure.

- Blue tempo or control: Fight over the Dreadnought commitment turn rather than over every cantrip or setup spell. Add role cards: sideboard `Brain Freeze` for long games and `Annul` only if revealed permanents make it live. Priority targets: stack interaction that answers `Stifle` or `Vision Charm`, bounce or removal aimed at `Phyrexian Dreadnought`, and card-advantage engines that outscale `Accumulated Knowledge`. Preserve `Foil` for protected kills when tapping out is necessary.

- Artifact or enchantment prison: Prevent the lock piece before it resolves when it blocks attacking, casting, or protecting `Phyrexian Dreadnought`. Add role cards: `Annul`, sideboard `Powder Keg`, and `Tsabo's Web` when visible nonbasic land abilities are part of the opponent's engine. Priority targets: permanents that stop combat, restrict spells, or generate repeated advantage. `Vision Charm` has artifact-related text, but Card text check required before relying on a specific artifact line.

- Big mana or land-engine decks: Present the fastest protected clock and counter the payoff rather than incidental setup. Add role cards: `Tsabo's Web`, conditional `Annul`, and sideboard `Brain Freeze` when the matchup visibly slows. Priority targets: mana engines that the opponent cannot function without, high-impact payoff spells, and removal that breaks the two-turn `Phyrexian Dreadnought` clock. Card text check required for exact `Tsabo's Web` land-ability coverage.

- Creature swarm or midrange: Make `Phyrexian Dreadnought` both a closer and a stabilizer, but do not expose it into obvious removal without protection unless the board forces action. Add role cards: sideboard `Powder Keg` for clustered low-cost permanents and `Essence Flare` only when a legal target changes a race or combat exchange. Priority targets: removal for `Phyrexian Dreadnought`, creatures that make racing impossible, and engines that recover after `Powder Keg`.

- Graveyard or spell-combo decks: Race first and interact with the payoff visible on stack or board. This registered deck has no dedicated graveyard hate, so `Counterspell`, `Foil`, and a fast `Phyrexian Dreadnought` are the main plan. Add role cards: `Annul` or `Hydroblast` only when revealed cards make those answers live, and sideboard `Brain Freeze` only when milling is a realistic win path rather than fuel for the opponent.

## Risk Summary

- Mana risk: The deck is almost entirely blue and runs `17 Island`, so one-land hands can function only with enough `Opt`, `Portent`, or `Impulse` and a clear path to the second land. `Gush` can create a burst of cards but returning `Island` may turn off `Counterspell` or delay a protected `Phyrexian Dreadnought` turn.

- Matchup risk: Removal-heavy opponents punish naked `Phyrexian Dreadnought` because the deck spends both the threat and `Stifle` or `Vision Charm` to establish it. Wait for `Counterspell`, `Foil`, `Hydroblast`, or `Annul` when time allows, but go now when the visible clock makes waiting worse.

- Draw risk: `Accumulated Knowledge`, `Gush`, `Flash of Insight`, and repeated cantrips can over-sculpt while the opponent advances board or burn pressure. Use selection to assemble threat plus protection, not to chase perfect hands after a legal winning commitment is already available.

- Over-sideboarding risk: Adding too many role cards can dilute the `Phyrexian Dreadnought` plus `Stifle` or `Vision Charm` core. Keep enough cantrips and protection to find and force the primary plan unless the matchup visibly requires a different axis.

- Graveyard risk: `Brain Freeze` can help long-game wins, but milling an opponent with graveyard payoffs can be harmful. Choose `Brain Freeze` only when legal action text and public context support it as a real closer or disruption line.

- Sweeper/removal risk: `Powder Keg` can answer boards but may be slow, symmetrical, or misaligned with visible mana values. Do not rely on it as a panic button unless counters and target costs line up through rules-engine output.

- Closer risk: The deck can run out of credible finishers if multiple `Phyrexian Dreadnought` copies are answered and `Brain Freeze` is not live. Protect the first decisive threat carefully, and treat `Essence Flare` as conditional race leverage rather than a default kill plan.

- Interaction risk: `Foil` protects while tapped low, but discarding an `Island` and another card can collapse future turns. Prefer `Counterspell` when mana is available, and reserve `Foil` for decisive stack fights or survival.

- Sequencing risk: Casting `Phyrexian Dreadnought` before holding or resolving `Stifle` or `Vision Charm` correctly can lose the threat to its own rules text. Follow the legal prompts exactly, and never assume the engine will offer a shortcut unless the action list explicitly does.

## Test Feedback Checklist

- Deciding factor: Identify whether the game was decided by an early protected `Phyrexian Dreadnought`, failed Dreadnought assembly, a counter war, pressure from creatures, burn pressure, or a long-game `Brain Freeze`/card-volume line.
- Mulligans: Record every opener's land count, whether it contained `Phyrexian Dreadnought`, `Stifle` or `Vision Charm`, and whether `Opt`, `Portent`, `Impulse`, or `Accumulated Knowledge` gave enough velocity to justify keeping.
- Mana: Note any turn where `17 Island` was insufficient, where a one-land keep missed the second `Island`, or where `Gush` returning `Island` disabled `Counterspell`, delayed protection, or made `Foil` costs harder.
- Combo assembly: Track how often `Phyrexian Dreadnought` plus `Stifle` or `Vision Charm` appeared by turn three, and whether the pilot waited for `Counterspell`, `Foil`, `Hydroblast`, or `Annul` when visible interaction made waiting correct.
- Protection quality: Record which opposing actions were stopped by `Counterspell`, `Foil`, `Hydroblast`, or `Annul`, and whether any protection was spent on low-impact spells before the decisive Dreadnought turn.
- Velocity: Check whether `Opt`, `Portent`, and `Impulse` found missing combo pieces or protection, and flag games where cantrips kept sculpting after a legal strong commitment was already available.
- Engines: Measure whether `Accumulated Knowledge`, `Gush`, and `Flash of Insight` generated meaningful extra decisions or merely consumed time while the opponent advanced a clock.
- Removal and sweepers: Record whether `Powder Keg` answered the visible board on time, whether its counter timing matched opposing mana values, and whether it conflicted with the deck's own threat plan.
- Sideboard cards: Note whether `Annul`, `Hydroblast`, sideboard `Brain Freeze`, `Essence Flare`, sideboard `Powder Keg`, and `Tsabo's Web` had legal targets or credible roles in the games where they were present.
- Closing: Record whether a resolved `Phyrexian Dreadnought` ended the game quickly, got blanked by blockers or removal, or needed `Essence Flare`, `Brain Freeze`, or additional protection to finish.
- Role discipline: Identify turns where the pilot should have been tempo-combo proactive versus control-reactive, especially when holding both cantrips and permission.
- Mistakes: Flag any action where the pilot cast `Phyrexian Dreadnought` without a visible legal `Stifle` or `Vision Charm` plan, tapped out before a known answer, or used `Foil` when `Counterspell` was available.
- Stranded cards: List cards stuck in hand at game end, especially extra `Phyrexian Dreadnought`, dead `Annul`, dead `Hydroblast`, slow `Accumulated Knowledge`, stranded `Brain Freeze`, or unusable `Essence Flare`.
- Overperformers and underperformers: Record which exact cards changed the game state decisively and which cards were repeatedly low-impact under the matchup's visible pressure.

## First Tuning Questions

- Threat density: Is `4 Phyrexian Dreadnought` enough when the first copy is answered, or do losses show the deck needs better protection timing rather than more closers?
- Enabler balance: Are `4 Stifle` and `4 Vision Charm` consistently live, or are games being lost because one enabler mode is unavailable, mistimed, or too dependent on exact rules text checks?
- Mana count: Does `17 Island` support `Counterspell` plus cantrip sequencing while enabling `Gush`, or do repeated missed second-land games justify revisiting the mana count?
- Card velocity mix: Are `Opt`, `Portent`, and `Impulse` the right balance of speed and selection, or does one cantrip repeatedly fail to find the missing Dreadnought, enabler, or protection piece on the critical turn?
- Card-volume package: Does `Accumulated Knowledge` win long games often enough, or does it conflict with the deck's need to commit before opponents stabilize?
- Free interaction cost: Is `Foil` protecting decisive turns, or is the discard cost losing too many games by stranding `Counterspell`, `Gush`, or follow-up selection?
- Main-deck singleton roles: Does main-deck `Brain Freeze`, `Flash of Insight`, or `Powder Keg` solve real game states, or are these slots too conditional for the expected field?
- Aggro plan: Against fast pressure, is the plan of early `Phyrexian Dreadnought` plus `Hydroblast`/`Powder Keg` sufficient, or does `Essence Flare` need a clearer role as race leverage?
- Control plan: Against counter-heavy or removal-heavy decks, does the second `Brain Freeze` provide a real alternate closer, or should the deck focus more tightly on protecting `Phyrexian Dreadnought`?
- Permanent-answer plan: Are `4 Annul` and the extra `Powder Keg` enough against artifact or enchantment engines, or are those cards too narrow when the opponent presents creatures and stack interaction instead?
- Red-matchup slots: Does `4 Hydroblast` convert red games, or do logs show the deck still loses to creature pressure, mana denial, or nonred answers despite drawing it?
- Land-engine plan: Does `2 Tsabo's Web` meaningfully disrupt visible land abilities, or is its slot allocation only justified in a narrower metagame? Card text check required for exact tactical assumptions.
- Role conflict: Does adding too many sideboard role cards dilute `Phyrexian Dreadnought` plus `Stifle`/`Vision Charm`, and which matchup results show the highest cost from reduced cantrip or permission density?
- Closing reliability: When games go long, is failure caused by losing the first Dreadnought, failing to protect it, drawing too many reactive cards, or lacking a credible secondary win condition?

## Veles Tactical Policy

### Policy: Mulligan For Dreadnought Assembly Or Fast Velocity
- Priority: High
- Decision families: mulligan
- Cards: Phyrexian Dreadnought; Stifle; Vision Charm; Island; Opt; Portent; Impulse; Counterspell; Foil
- Phase windows: opening hand, mulligan decisions, post-mulligan bottom choices
- Runtime cues: prompt:mulligan; prompt:bottom cards
- Use when: choosing keep, mulligan, or bottom cards from visible opening-hand information.
- Avoid when: the engine has already locked the hand or asks a non-mulligan decision.
- Instructions: Keep hands with `Island`, `Phyrexian Dreadnought`, and `Stifle` or `Vision Charm` unless the hand cannot cast spells. Keep slower hands with two `Island`, selection, and protection when no fast pressure is visible yet. Mulligan hands with no `Island`, no selection, and no Dreadnought path. Bottom redundant expensive or late cards before combo pieces, one-mana selection, and required mana.
- Pilot skill floor: medium
- No-API allowed: no
- Light-model allowed: yes

### Policy: Early Setup Finds First Threat Or Enabler
- Priority: Medium
- Decision families: selection, mana, priority
- Cards: Opt; Portent; Impulse; Phyrexian Dreadnought; Stifle; Vision Charm; Island
- Phase windows: turns 1-3 main phases, opponent end step
- Runtime cues: action:cast Opt; action:cast Portent; action:cast Impulse
- Use when: selecting among cantrips before the first `Phyrexian Dreadnought` has been safely enabled.
- Avoid when: a legal protected Dreadnought commitment is already available and waiting gives the opponent another turn of pressure.
- Instructions: Spend one-mana selection to assemble `Phyrexian Dreadnought` plus `Stifle` or `Vision Charm`. Use `Impulse` when mana is available and the missing piece is more important than holding two blue for `Counterspell`. Preserve an `Island` line that supports the next turn's enabler and protection.
- Pilot skill floor: medium
- No-API allowed: no
- Light-model allowed: yes

### Policy: Commit Phyrexian Dreadnought Only With Enabler Plan
- Priority: High
- Decision families: priority, interaction, mana
- Cards: Phyrexian Dreadnought; Stifle; Vision Charm; Counterspell; Foil; Island
- Phase windows: own main phase, stack response to Dreadnought trigger
- Runtime cues: action:cast Phyrexian Dreadnought; prompt:trigger Phyrexian Dreadnought
- Use when: deciding whether to start the Dreadnought line or wait.
- Avoid when: no visible legal `Stifle` or `Vision Charm` follow-up exists for the Dreadnought trigger.
- Instructions: Start the combo when the action list supports casting `Phyrexian Dreadnought` and the hand or stack gives a visible way to neutralize the sacrifice trigger. Prefer waiting when known or obvious interaction can answer the threat and the hand can hold `Counterspell` or `Foil` next turn. Commit faster when the opponent's visible clock makes waiting worse than risking the stack fight.
- Pilot skill floor: high
- No-API allowed: no
- Light-model allowed: yes

### Policy: Target Own Dreadnought Trigger With Stifle
- Priority: Medium
- Decision families: interaction, priority
- Cards: Stifle; Phyrexian Dreadnought
- Phase windows: stack response to Phyrexian Dreadnought enters-the-battlefield trigger
- Runtime cues: action:target Phyrexian Dreadnought Stifle; action:target trigger Stifle
- Use when: a legal `Stifle` target action names the visible `Phyrexian Dreadnought` trigger you control.
- Avoid when: the legal action text targets an opposing ability, a different permanent, or a trigger not caused by your `Phyrexian Dreadnought`.
- Instructions: Select the legal action that applies `Stifle` to the visible `Phyrexian Dreadnought` sacrifice trigger. After that target is selected, continue through any required mana or priority prompts without changing targets.
- Pilot skill floor: low
- No-API allowed: yes
- Light-model allowed: yes

### Policy: Use Vision Charm As Dreadnought Enabler Only From Visible Mode Text
- Priority: Medium
- Decision families: selection, interaction, priority
- Cards: Vision Charm; Phyrexian Dreadnought
- Phase windows: response to Dreadnought trigger, own main phase stack decisions
- Runtime cues: action:choose mode Vision Charm; action:target Phyrexian Dreadnought Vision Charm
- Use when: legal action text shows a `Vision Charm` mode or target that phases out or otherwise protects the visible `Phyrexian Dreadnought` from its pending problem. Card text check required for exact mode handling.
- Avoid when: the legal action text does not name `Phyrexian Dreadnought`, does not show the needed mode, or asks for a non-deterministic mode choice.
- Instructions: Use `Vision Charm` as an enabler only when Forge exposes the exact legal mode and target. Route uncertain mode selection through light-model reasoning because the card has multiple modes and the correct mode depends on the stack.
- Pilot skill floor: medium
- No-API allowed: no
- Light-model allowed: yes

### Policy: Protect Resolved Or Resolving Threat
- Priority: High
- Decision families: interaction, priority, mana
- Cards: Counterspell; Foil; Hydroblast; Annul; Phyrexian Dreadnought; Island
- Phase windows: any priority window with opposing spell or ability on stack
- Runtime cues: stack:opponent spell; action:cast Counterspell; action:cast Foil; action:cast Hydroblast; action:cast Annul
- Use when: an opposing stack object can remove, counter, lock, race, or otherwise neutralize the Dreadnought plan.
- Avoid when: the stack object is low impact compared with saving permission for a visible answer or lethal-race stop.
- Instructions: Use `Counterspell` before `Foil` when mana is available and preserving cards matters. Use `Foil` when tapped low, when the protected Dreadnought attack will decide the game, or when losing the stack fight loses the game. Use `Hydroblast` only against legal red objects. Use `Annul` only against legal artifact or enchantment objects.
- Pilot skill floor: high
- No-API allowed: no
- Light-model allowed: yes

### Policy: Spend Foil Only For Decisive Stack Fights
- Priority: Medium
- Decision families: interaction, priority, mana
- Cards: Foil; Island; Gush; Counterspell; Phyrexian Dreadnought
- Phase windows: any stack decision
- Runtime cues: action:cast Foil; prompt:discard for Foil
- Use when: deciding whether the free counter and discard cost are justified.
- Avoid when: `Counterspell` can legally answer the same object and preserving cards is not immediately dangerous.
- Instructions: Treat `Foil` as emergency protection, not routine permission. Discard extra `Island` and least-needed card first; avoid discarding the only enabler, only `Phyrexian Dreadnought`, or the card that supports the next protected commitment unless the current stack fight decides survival.
- Pilot skill floor: high
- No-API allowed: no
- Light-model allowed: yes

### Policy: Manage Island Count Before Gush
- Priority: Medium
- Decision families: mana, priority, selection
- Cards: Gush; Island; Counterspell; Foil; Impulse
- Phase windows: own main phase, opponent end step, emergency stack windows
- Runtime cues: action:cast Gush; action:return Island
- Use when: `Gush` is legal and returning `Island` changes available mana or future protection.
- Avoid when: returning `Island` disables required `Counterspell`, blocks a Dreadnought enabler turn, or leaves no blue mana for visible stack interaction.
- Instructions: Cast `Gush` to refuel when land returns do not break the current turn's required blue mana. Prefer end-step or protected windows when possible. Use `Gush` more aggressively when the hand is empty, `Foil` needs cards, or the game has shifted to long resource play.
- Pilot skill floor: medium
- No-API allowed: no
- Light-model allowed: yes

### Policy: Sequence Accumulated Knowledge For Card Volume
- Priority: Low
- Decision families: selection, priority, mana
- Cards: Accumulated Knowledge; Island; Counterspell
- Phase windows: opponent end step, own main phase when shields are acceptable
- Runtime cues: action:cast Accumulated Knowledge
- Use when: the current turn is about card volume rather than immediate Dreadnought commitment or survival.
- Avoid when: spending mana turns off needed `Counterspell` or delays a legal protected Dreadnought line under pressure.
- Instructions: Cast early copies when mana would otherwise go unused and the deck needs velocity. Cast later copies in windows that preserve stack discipline. Do not chase extra cards while a visible opponent clock requires committing a threat or answering the board.
- Pilot skill floor: medium
- No-API allowed: no
- Light-model allowed: yes

### Policy: Use Flash Of Insight As Late Selection
- Priority: Low
- Decision families: selection, priority, mana
- Cards: Flash of Insight; Island; Gush; Accumulated Knowledge
- Phase windows: late main phase, opponent end step, graveyard-resource windows
- Runtime cues: action:cast Flash of Insight; action:flashback Flash of Insight
- Use when: the game has slowed and selection can find protection, enabler, threat, or alternate close.
- Avoid when: mana or graveyard cost would block an immediate defensive spell or protected threat line.
- Instructions: Treat `Flash of Insight` as a long-game filter. Card text check required for exact flashback cost and selection depth at runtime. Let visible legal actions and available resources determine whether casting now is safe.
- Pilot skill floor: medium
- No-API allowed: no
- Light-model allowed: yes

### Policy: Use Brain Freeze As Alternate Finish After Spell Volume
- Priority: Medium
- Decision families: priority, interaction, selection
- Cards: Brain Freeze; Gush; Accumulated Knowledge; Opt; Portent; Impulse; Counterspell; Foil
- Phase windows: late turn after multiple spells, counter wars, end-step windows
- Runtime cues: action:cast Brain Freeze; storm count; target opponent Brain Freeze
- Use when: visible spell count and opponent library count make `Brain Freeze` a real closing line or force a decisive resource exchange.
- Avoid when: casting it does not materially threaten the opponent and would consume protection needed for `Phyrexian Dreadnought`.
- Instructions: Prefer `Brain Freeze` after cantrip chains, `Gush`, and counter exchanges have increased storm count. Target opponent only when the legal action text supports that target and the line is meant to mill the opponent.
- Pilot skill floor: high
- No-API allowed: no
- Light-model allowed: yes

### Policy: Target Opponent With Brain Freeze Payoff
- Priority: Low
- Decision families: selection, priority
- Cards: Brain Freeze
- Phase windows: Brain Freeze target prompt
- Runtime cues: action:target opponent Brain Freeze
- Use when: the only strategic plan for the cast `Brain Freeze` is milling the opponent and legal action text offers `target opponent` for `Brain Freeze`.
- Avoid when: the action list includes multiple non-opponent targets or the cast was not selected as a mill payoff.
- Instructions: Select the visible opponent target for `Brain Freeze`. Do not infer library contents or lethal certainty beyond visible library count and engine output.
- Pilot skill floor: low
- No-API allowed: yes
- Light-model allowed: yes

### Policy: Powder Keg Board Control Gate
- Priority: Medium
- Decision families: interaction, priority, mana
- Cards: Powder Keg
- Phase windows: own main phase, upkeep counter decisions, activation windows
- Runtime cues: action:cast Powder Keg; action:activate Powder Keg; prompt:add counter Powder Keg
- Use when: visible permanents make `Powder Keg` a board-control plan or survival tool.
- Avoid when: the counter number would destroy your important permanent or the board does not justify spending the turn.
- Instructions: Cast `Powder Keg` against creature or artifact pressure that the deck cannot race. Add counters only toward a visible mana value plan. Activate only when the visible destroyed permanents improve survival or clear a blocker/lock piece.
- Pilot skill floor: high
- No-API allowed: no
- Light-model allowed: yes

### Policy: Combat With Enabled Phyrexian Dreadnought
- Priority: High
- Decision families: combat, priority, interaction
- Cards: Phyrexian Dreadnought; Essence Flare; Counterspell; Foil
- Phase windows: declare attackers, declare blockers, combat trick windows, damage steps
- Runtime cues: action:attack with Phyrexian Dreadnought; combat:blocked Phyrexian Dreadnought
- Use when: deciding whether to attack, hold back, or protect combat with a resolved `Phyrexian Dreadnought`.
- Avoid when: visible blockers, damage prevention, or removal make attacking worse than holding defense and the opponent is not under immediate closing pressure.
- Instructions: Attack when the Dreadnought advances a two-turn or immediate clock and protection can cover visible answers. Hold back only when defense prevents lethal or when attacking into visible board text risks losing the only threat for no damage. Use `Essence Flare` only if legal and its exact combat impact is confirmed by card text check required.
- Pilot skill floor: high
- No-API allowed: no
- Light-model allowed: yes

### Policy: Sideboard Without Diluting The Core
- Priority: High
- Decision families: sideboard, pregame
- Cards: Annul; Brain Freeze; Essence Flare; Hydroblast; Powder Keg; Tsabo's Web; Phyrexian Dreadnought; Stifle; Vision Charm
- Phase windows: between games, sideboard lock
- Runtime cues: prompt:sideboard; match stage:game 2; match stage:game 3
- Use when: choosing post-board configuration from known matchup and previous-game public evidence.
- Avoid when: no legal sideboard request is active.
- Instructions: Add `Hydroblast` against red-heavy opponents, `Annul` against artifact or enchantment reliance, `Powder Keg` against swarm or low-cost permanents, `Brain Freeze` for slow counter-heavy games, `Essence Flare` for creature-race plans only after card text check required, and `Tsabo's Web` only when opposing land abilities are a visible or matchup-defined plan. Preserve enough `Phyrexian Dreadnought`, `Stifle`, `Vision Charm`, blue mana, and selection to remain a tempo-combo deck.
