# Strategy Specifications
## Deck Name And Archetype
Niv to Light is a Pioneer five-color midrange-control toolbox deck built around 4 Bring to Light, 2 Niv-Mizzet Reborn, 1 Niv-Mizzet, Supreme, 2 Omnath, Locus of Creation, 4 Up the Beanstalk, 4 Ancient Cornucopia, and 4 Leyline Binding. The registered strategy is not a pure tap-out ramp deck or a pure permission deck; it is a high-card-quality stabilizer that turns fixing into access, turns multicolor spells into card advantage, and uses a large tutor/value package to answer the visible board before winning through repeated oversized threats.

Validation status: active format is Pioneer, the registered main deck contains 80 cards, the sideboard contains 15 cards, and the supplied format-aware validation result passes. The 80-card count strongly suggests a Yorion, Sky Nomad configuration, but Veles should treat Yorion, Sky Nomad as a registered sideboard card and only treat it as companion-available when the runtime pregame or rules engine explicitly exposes that legal option.

Archetype tags normalize to midrange, control, and toolbox. The list is best classified as a hybrid Niv to Light shell rather than a fully stock list because it combines classic Bring to Light and Niv-Mizzet Reborn incentives with newer or less universal components such as Professor Dellian Fel, Ultima, Vibrant Outburst, Ancient Cornucopia, Overlord of the Hauntwoods, and the Verge lands. Runtime decisions should therefore respect this guide over generic Niv assumptions whenever legal actions and visible state expose these exact cards.

Primary color identity and mana shape are five-color, with 4 Sylvan Caryatid, 4 Ancient Cornucopia, 4 Fabled Passage, triomes, shock lands, Verge lands, and typed multicolor lands supporting Bring to Light, Leyline Binding, Omnath, Locus of Creation, and Niv-Mizzet Reborn. Mana quality is a strategic concern because early untapped sources decide whether Lightning Helix, Abrupt Decay, Vanishing Verse, Deafening Clarion, and Culling Ritual can stabilize before the deck’s five-mana plays matter. Veles should not assume all colors are available from deck identity; it must read current lands, tapped status, floating mana, and legal payment prompts.

Role concern: the deck’s default posture is answer-first until it reaches a stable turn where Bring to Light, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Beza, the Bounding Spring, or Yorion, Sky Nomad can convert parity into a decisive resource advantage. The pilot should avoid spending flexible removal on low-impact permanents when life total, opposing clock, or future tutor targets make a higher-value answer likely, but it should also avoid dying with powerful five-mana cards in hand.

Card text confidence status: Card text check required for Professor Dellian Fel, Ultima, Erode, Surrak Dragonclaw, and any newer land or spell whose exact Oracle text is not provided by the rules engine. Tactical use of those cards in later sections should remain conditional on visible legal actions and engine-exposed modes, targets, costs, and outcomes.

Opponent information status: no specific opponent, matchup, game state, or metagame target was supplied for this section. The assembled guide should stay deck-specific and Pioneer-aware while treating opponent identity as unknown until Veles receives matchup labels, revealed cards, public game actions, or sideboarding context from the engine.

## Thesis
Niv to Light assembles five-color mana, early stabilization, and high-impact multicolor payoffs into a toolbox plan where 4 Bring to Light turns the library into the best legal answer or threat for the visible board. The deck wins by surviving the first pressure wave, trading one-for-one or one-for-many with Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Deafening Clarion, Culling Ritual, and Kolaghan's Command, then pulling ahead with Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Up the Beanstalk, Beza, the Bounding Spring, Overlord of the Hauntwoods, Professor Dellian Fel, or a sideboard value card.

Prioritize mana quality before ambition because the deck's power is gated by exact colors, domain, tapped lands, and whether Bring to Light can access the needed mana value. Keep early turns focused on casting Sylvan Caryatid, Ancient Cornucopia, Up the Beanstalk, and untapped interaction when the opponent is pressuring life total; delay greedy tapped-land sequencing when it prevents Lightning Helix, Abrupt Decay, Vanishing Verse, or Leyline Binding from answering a threatening permanent.

Win by converting stabilization into repeated card advantage rather than by racing from turn one. Niv-Mizzet Reborn is a refill and body, Bring to Light is a flexible bridge into the correct effect, Omnath, Locus of Creation rewards land sequencing when it is safe, and Up the Beanstalk makes expensive spells and Leyline Binding-style plays more resource-positive when engine text and legal triggers confirm the draw.

Do not play this deck as pure ramp, pure combo, or pure draw-go control. It should not ignore the board to rush Niv-Mizzet Reborn into open danger when a stabilizing Bring to Light line is better, and it should not hoard removal so long that visible attackers, planeswalkers, graveyard engines, or combo pieces become unmanageable.

Use runtime output as the source of truth for card text, targets, modes, and legality. Card text check required for Professor Dellian Fel, Ultima, Erode, Surrak Dragonclaw, and newer lands or spells when the engine does not expose enough text; choose those actions only when visible legal actions make their tactical role clear.

## Role Package
- Threats: Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Beza, the Bounding Spring, Professor Dellian Fel, Valki, God of Lies, and sideboard Yorion, Sky Nomad are the main bodies that end games after parity. Deploy them when the visible board is stable enough that losing tempo will not cost the game, or when the body itself is the stabilizing action exposed by the engine.

- Payoffs: Bring to Light is the defining payoff because it converts five-color access into the best legal spell for the present problem. Niv-Mizzet Reborn and Niv-Mizzet, Supreme reward multicolor density, Omnath, Locus of Creation rewards land drops and fetch timing, Up the Beanstalk rewards expensive or cost-reduced plays when triggers are legal, and Ancient Cornucopia can become a scaling resource if its engine text is active.

- Engines: Up the Beanstalk, Ancient Cornucopia, Omnath, Locus of Creation, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Professor Dellian Fel, Overlord of the Hauntwoods, and Yorion, Sky Nomad are the long-game machinery. Prefer an engine when life total is stable, the opponent is low on pressure, or the current interaction suite already covers the visible threats.

- Velocity: Bring to Light is the primary selection spell, Fabled Passage fixes and can enable landfall sequencing, and multicolor ETB or reveal payoffs provide card flow when the engine confirms them. Treat Vibrant Outburst and Ultima as conditional velocity or toolbox pieces only after card text check or engine-exposed legal outcomes.

- Interaction: Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Kolaghan's Command, Deafening Clarion, Culling Ritual, Beza, the Bounding Spring, and sideboard Erode, Dovin's Veto, Kaervek, the Spiteful, Tolsimir, Friend to Wolves, Rest in Peace, Unmoored Ego, Ultima, and Sphinx's Revelation form the answer package. Spend the narrowest answer that fully handles the visible problem while preserving Bring to Light for problems no held card can answer.

- Protection: Sylvan Caryatid protects the mana plan by resisting common creature interaction if its engine text confirms that role, Dovin's Veto protects expensive commitments after sideboard, Surrak Dragonclaw may protect creature commitments if legal text supports it, and sequencing protects threats by forcing the opponent to answer earlier engines first.

- Recursion: Kolaghan's Command is the clearest registered recursion-adjacent card when legal modes expose returning a creature or grinding resources. Niv-Mizzet, Supreme may imply graveyard or multicolor reuse only if the rules engine exposes legal actions; otherwise do not assume recursion from name alone.

- Mana: Sylvan Caryatid, Ancient Cornucopia, Fabled Passage, the triomes, shock lands, Verge lands, and five-color typed lands are the deck's access layer. Sequence lands to unlock white-red for Lightning Helix, black-green for Abrupt Decay, white-black for Vanishing Verse, broad domain for Leyline Binding, and five colors for Bring to Light before prioritizing luxury colors.

- Sideboard modules: Dovin's Veto covers stack fights and noncreature haymakers; Rest in Peace covers graveyard reliance; Kaervek, the Spiteful covers small-creature boards if text confirms; Unmoored Ego covers named-card strategies; Erode covers artifact/enchantment pressure if text confirms; Sphinx's Revelation supports attrition; Tolsimir, Friend to Wolves supports creature stabilization; Surrak Dragonclaw supports creature-threat mirrors if text confirms; Ultima adds a second copy of the flexible effect after card text check; Yorion, Sky Nomad supports long-game blink/value only when pregame or sideboard legality exposes it.

## Primary Win Conditions
- Prioritize the Bring to Light toolbox finish when five colors are available and the visible board demands a specific answer or payoff. Setup requires reliable domain/color access from Sylvan Caryatid, Ancient Cornucopia, Fabled Passage, triomes, shock lands, and Verge lands; execution is casting Bring to Light for the legal card that either stabilizes now or creates the next-turn winning position. Disruption to respect is open counterplay, graveyard hate only when the chosen line uses the graveyard, pressure that punishes tapping out, and permanent types your current removal cannot answer afterward.

- Use Niv-Mizzet Reborn as the primary refill-and-close threat once life total and board are not collapsing. Setup requires enough colors to cast it and enough multicolor density left in library to make the reveal meaningful; execution is resolving Niv-Mizzet Reborn, refilling on interactive pairs when the engine exposes those cards, then attacking while the new hand answers the opponent's recovery. Prioritize this line when both players are trading resources, when Up the Beanstalk or Omnath, Locus of Creation is not immediately required, or when the opponent has exhausted visible pressure.

- Use Omnath, Locus of Creation plus land sequencing as the stabilizing value kill when land drops and Fabled Passage timing are available. Setup requires safe access to Omnath's colors and at least one landfall opportunity if the engine confirms relevant triggers; execution is sequencing lands after Omnath to gain resources, stabilize life when legal, and turn later land drops into tempo or cards. Prioritize this line against creature pressure or attrition when resolving a four-mana permanent is safer than waiting for Niv-Mizzet Reborn.

- Use Up the Beanstalk as the long-game engine when early survival is already covered. Setup is resolving Up the Beanstalk before high-cost or cost-reduced spells; execution is chaining Leyline Binding, Bring to Light, Niv-Mizzet Reborn, Omnath, Locus of Creation, Overlord of the Hauntwoods, Beza, the Bounding Spring, or other engine-confirmed triggers into extra cards. Prioritize this line when the opponent is not presenting lethal pressure and the game will be decided by resource volume.

- Use creature pressure to end games after stabilization, not as an unsupported race. Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Beza, the Bounding Spring, Professor Dellian Fel, Valki, God of Lies, and Sylvan Caryatid only attack when combat output is favorable by visible board state. Card text check required for Professor Dellian Fel; commit it as a win path only when rules-engine actions reveal a concrete advantage.

## Secondary Win Conditions
- Convert removal into inevitability when no single payoff is safe. Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Deafening Clarion, Culling Ritual, and Kolaghan's Command can buy enough turns for any later threat to win; choose the narrowest answer that handles the current permanent while preserving broader tools for unknown topdecks.

- Finish low-life opponents with Lightning Helix only when the engine exposes a legal target and the burn meaningfully changes the clock. Prefer Lightning Helix on creatures when behind on board or life, but redirect toward the opponent when visible life totals make it part of a lethal or near-lethal sequence and no must-kill threat remains.

- Use Kolaghan's Command as a flexible attrition bridge when its legal modes matter more than raw size. If the engine offers recursion, damage, discard, or artifact interaction modes, choose the mode pair that advances the current resource fight; do not assume a mode exists unless it is visible in legal actions.

- Use Valki, God of Lies as disruption or as a late-game alternate threat only through engine-confirmed legal text. Early Valki can pressure hidden-hand strategies if the action reveals a legal discard/exile style effect, while late-game options may become a payoff if the rules engine exposes them; Card text check required before treating the back face as available.

- Use Niv-Mizzet, Supreme as a secondary engine threat when the visible game is about repeated multicolor value. Card text check required for exact recursion or casting permissions; if legal actions expose graveyard or multicolor reuse, prioritize it when the graveyard contains relevant interaction and opponent pressure is contained.

- Use Overlord of the Hauntwoods and Beza, the Bounding Spring as stabilizing bodies that become win conditions after they answer the immediate deficit. Prioritize them when their engine-exposed effects create mana, blockers, life, or cards that let the deck turn the corner without exposing Bring to Light into a known answer.

## Emergency Lines
- When behind on life, spend interaction for survival before maximizing card advantage. Lightning Helix, Beza, the Bounding Spring, Deafening Clarion, Leyline Binding, Vanishing Verse, Abrupt Decay, and Bring to Light for a stabilizer take priority over Up the Beanstalk setup, slow Niv-Mizzet Reborn turns, or speculative Omnath, Locus of Creation sequencing.

- When behind on board, answer the threat that changes the next combat math first. Use Leyline Binding or Vanishing Verse for the largest or hardest-to-replace permanent, Abrupt Decay for cheap must-answer permanents, Maelstrom Pulse for clustered names or broad permanent pressure when legal, Deafening Clarion or Culling Ritual for sweeper roles when visible creatures and permanents make the exchange favorable.

- When behind on cards, choose engines only if the current board can survive the tempo loss. Up the Beanstalk, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Kolaghan's Command, and Bring to Light can recover resources, but a live attacker, combo piece, or planeswalker-equivalent permanent must be answered first if it will snowball before those cards matter.

- When behind on mana or colors, protect the access layer over luxury plays. Keep Sylvan Caryatid alive when possible, use Fabled Passage for missing colors rather than perfect domain when a spell is stranded, and cast Ancient Cornucopia or Up the Beanstalk only when doing so does not skip required interaction.

- When engines are removed, shift to answer-then-threat sequencing. Trade removal aggressively, resolve any surviving large creature, and use Bring to Light as the next best role-player rather than waiting for the ideal Niv-Mizzet Reborn or Up the Beanstalk turn.

- When graveyard recursion is relevant, trust only public zones and engine-exposed permissions. If Kolaghan's Command or Niv-Mizzet, Supreme offers a legal graveyard action, use it for the creature or spell that best stabilizes the visible board; otherwise do not plan around hidden or assumed recursion.

- When facing combo or a must-answer engine, treat Bring to Light and targeted interaction as emergency disruption. Name or target only what the rules engine exposes as legal, prioritize preventing the opponent's next decisive action over developing a payoff, and accept a lower-value answer if waiting risks losing before the next priority window.

## Resource Model
- Life is a spendable buffer only after the next combat step is contained. Use shock lands such as Watery Grave, Temple Garden, Stomping Ground, Sacred Foundry, Overgrown Tomb, Blood Crypt, and Breeding Pool untapped when the spell unlocked is Lightning Helix, Abrupt Decay, Vanishing Verse, Sylvan Caryatid, Ancient Cornucopia, or Bring to Light on curve; prefer tapped triomes and Verge lands when visible pressure is low.

- Hand size is the deck's main inevitability resource. Up the Beanstalk, Niv-Mizzet Reborn, Bring to Light, Omnath, Locus of Creation, Kolaghan's Command, Beza, the Bounding Spring, Niv-Mizzet, Supreme, and Sphinx's Revelation after sideboard should turn one card into multiple resources, but only after interaction has prevented the opponent from converting tempo into lethal pressure.

- Mana access is more important than raw land count in the first four turns. Protect hands that produce green for Sylvan Caryatid or Ancient Cornucopia, then build toward all five colors for Bring to Light, Leyline Binding efficiency, Niv-Mizzet Reborn, and Omnath, Locus of Creation. A four-land hand without green or without early interaction is often slower than a two-land hand with Fabled Passage plus Sylvan Caryatid.

- Board presence is defensive until a payoff resolves. Sylvan Caryatid, Beza, the Bounding Spring, Omnath, Locus of Creation, Overlord of the Hauntwoods, Professor Dellian Fel, Valki, God of Lies, Niv-Mizzet Reborn, and Niv-Mizzet, Supreme become attackers only after visible opposing pressure is answered or the attack does not expose a stabilizing blocker.

- Graveyard value is conditional and public-zone based. Kolaghan's Command and Niv-Mizzet, Supreme may create recursion lines only when the engine exposes legal graveyard actions; otherwise treat graveyards mainly as information for resource tracking, Rest in Peace sideboard planning, and opposing recursion pressure.

- Exile is mostly an answer zone and must not be treated as accessible unless legal actions say so. Leyline Binding, Vanishing Verse, Valki, God of Lies, Rest in Peace, and Unmoored Ego can move cards into exile; use that information to track answered threats and sideboard hate performance, not to assume future access.

- Lands are spell quality, not just mana. Fabled Passage fixes missing basics and can support Omnath, Locus of Creation landfall sequencing when legal; Indatha Triome, Jetmir's Garden, Ketria Triome, Raugrin Triome, Spara's Headquarters, Xander's Lounge, Zagoth Triome, and Ziatora's Proving Ground improve domain and color density but cost tempo when tapped.

- Sacrifice fodder is scarce, so do not spend permanents casually. Card text check required for Culling Ritual, Erode, and Ultima in exact tactical exchanges; treat any sacrifice, destroy, or resource-conversion mode as conditional on visible legal actions and avoid sacrificing Sylvan Caryatid, Ancient Cornucopia, or engine permanents unless the payoff is survival or a decisive swing.

- Tempo is bought with cheap interaction and spent on engines. Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Deafening Clarion, Culling Ritual, and Dovin's Veto after sideboard should prevent the opponent's high-leverage turn so Up the Beanstalk, Bring to Light, Niv-Mizzet Reborn, or Sphinx's Revelation can take over.

- Information changes tutor and answer priorities. Use visible hand, revealed cards, graveyards, companion status, and sideboarded cards to decide whether Bring to Light should find pressure, removal, a sweeper, Unmoored Ego, Surrak Dragonclaw, Tolsimir, Friend to Wolves, Kaervek, the Spiteful, or another registered bullet; never infer exact hidden cards without reveal data.

## Mana Guide
- Nonbasic sequencing must explicitly account for Temple Garden and Jetmir's Garden because they are among the key land names that shape early green/white access, domain, and tapped-land timing. Prefer Temple Garden when the hand needs untapped green or white for Sylvan Caryatid, Ancient Cornucopia, Lightning Helix, Vanishing Verse, or Leyline Binding, and prefer Jetmir's Garden on low-pressure turns when the domain type mix matters more than immediate mana.

- Prioritize green plus a second color in opening hands because Sylvan Caryatid and Ancient Cornucopia are the cleanest bridges into five-color play. Keep hands that can cast one of them by turn two or have Fabled Passage plus relevant early interaction; mulligan hands that require multiple tapped lands before casting any spell against fast visible archetypes.

- Build domain deliberately for Leyline Binding and Bring to Light. Sequence triomes and shock lands so at least four to five basic land types become available by the midgame, but fetch the missing functional color first when a hand contains stranded Abrupt Decay, Lightning Helix, Vanishing Verse, Up the Beanstalk, Omnath, Locus of Creation, or Bring to Light.

- Use Fabled Passage for color repair before landfall value. If Omnath, Locus of Creation is already legal and safe, hold Fabled Passage when the extra landfall timing matters; otherwise crack it early enough to cast the next required spell and avoid passing with interaction stranded.

- Play tapped lands early when the turn has no required instant-speed answer. Indatha Triome, Jetmir's Garden, Ketria Triome, Raugrin Triome, Spara's Headquarters, Xander's Lounge, Zagoth Triome, Ziatora's Proving Ground, Sunbillow Verge, Floodfarm Verge, Bleachbone Verge, Hushwood Verge, and Wastewood Verge should enter on low-pressure turns; shock lands should enter untapped when they unlock removal, Caryatid, Cornucopia, or Bring to Light timing.

- Sequence lands before draw effects when landfall or mana availability is required this turn. Play a land before casting Omnath, Locus of Creation only if the engine requires mana now and no landfall trigger is being saved; after Omnath is on board, prefer casting Omnath first, then playing Fabled Passage or another land if legal actions and mana allow.

- Delay land drops before selection only when the deck can use the new information. If Up the Beanstalk, Niv-Mizzet Reborn, Bring to Light, Sphinx's Revelation, or another legal draw/search action may reveal a better land plan and no current mana is needed, wait on the land drop; if interaction must be held up or a spell must be cast, play the land first.

- Preserve white, black, and blue access for answer spread. Lightning Helix and Deafening Clarion pressure red-white access, Abrupt Decay and Maelstrom Pulse pressure black-green access, Vanishing Verse pressures white-black access, Dovin's Veto pressures white-blue after sideboard, and Bring to Light rewards the widest color set.

- Treat colorless-looking abundance as a trap if it lacks exact colors. Multiple triomes and shock lands are excellent only when they cast early spells on time; a hand with lands that enter tapped and no Sylvan Caryatid, Ancient Cornucopia, Lightning Helix, Abrupt Decay, or Vanishing Verse should be judged as slow even if it has many lands.

- Use Ancient Cornucopia as fixing before value unless survival demands removal first. Card text check required for exact counters or life text, but tactically it should support five-color access for Bring to Light, Niv-Mizzet Reborn, Omnath, Locus of Creation, Leyline Binding, and sideboard bullets when the opponent is not forcing an immediate answer.

## Mulligan Guide
- Strong keeps prioritize castable fixing plus action. Keep two to four lands with green access, Sylvan Caryatid or Ancient Cornucopia, and at least one relevant spell such as Lightning Helix, Abrupt Decay, Vanishing Verse, Up the Beanstalk, Leyline Binding, or Bring to Light; this deck is favored when it reaches turn four with colors intact and life total not collapsing.

- Strong payoff keeps need early bridge cards, not only expensive cards. A hand with Fabled Passage, a green source, Sylvan Caryatid, Up the Beanstalk, Leyline Binding, Bring to Light, and any third land is excellent because it fixes mana, buys tempo, and converts into a tutor or Niv-Mizzet Reborn turn.

- Medium keeps are interaction-heavy hands with imperfect fixing. Keep three lands plus Lightning Helix and Vanishing Verse or Abrupt Decay against visible creature pressure even without Up the Beanstalk, especially on the draw; keep only if the lands cast the first answer on time or Fabled Passage can find the missing color.

- Medium keeps include slow value hands on the play against unknown or slower opponents. Three lands, Ancient Cornucopia, Up the Beanstalk, Bring to Light, and Niv-Mizzet Reborn is acceptable if at least one early spell is legal by turn two or three; it becomes risky if all lands enter tapped and the opponent can punish the first two turns.

- Risky keeps are one-accelerant hands that fold to missing land drops. Two lands plus Sylvan Caryatid, Bring to Light, Omnath, Locus of Creation, Leyline Binding, and Niv-Mizzet Reborn is keepable only when both lands cast Sylvan Caryatid and the deck has a realistic third land path; do not assume the draw step fixes the hand.

- Automatic ships lack early mana or legal interaction. Mulligan zero-land, one-land without Fabled Passage plus turn-two Sylvan Caryatid or Ancient Cornucopia, five-plus-land hands with no Up the Beanstalk or Bring to Light, and hands that cannot cast any nonland spell before turn three against unknown opposition.

- Automatic ships also include expensive color piles. Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Bring to Light, Beza, the Bounding Spring, Overlord of the Hauntwoods, and only tapped or off-color lands is not a keep just because the cards are powerful.

- Matchup-dependent keeps change with visible speed. Against fast red or creature boards, value Lightning Helix, Leyline Binding, Deafening Clarion, Abrupt Decay, Vanishing Verse, Beza, the Bounding Spring, and early untapped red-white or black-green access; against slower decks, value Up the Beanstalk, Bring to Light, Niv-Mizzet Reborn, Ancient Cornucopia, and Dovin's Veto after sideboard.

- Play/draw changes tolerance for tapped lands. On the play, keep slower triome-heavy hands when they still cast Sylvan Caryatid, Ancient Cornucopia, or Up the Beanstalk by turn two or three; on the draw, require Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, or a clear turn-two stabilizer against unknown pressure.

- Trap hands overvalue domain without tempo. Indatha Triome, Ketria Triome, Xander's Lounge, Zagoth Triome, Bring to Light, Niv-Mizzet Reborn, and Omnath, Locus of Creation looks functional but should usually be shipped if no turn-two play or early answer is available.

- Trap hands overvalue Up the Beanstalk without castable high-cost follow-up. Keep Up the Beanstalk when the hand also has Leyline Binding, Bring to Light, Beza, the Bounding Spring, Overlord of the Hauntwoods, Niv-Mizzet Reborn, or enough interaction to survive; do not keep it as the only plan in a color-stalled hand.

## Turn Arc
- Turn 1 should establish the most constrained future color. Lead on Fabled Passage for a missing basic when turn-two Sylvan Caryatid, Ancient Cornucopia, Lightning Helix, Abrupt Decay, or Vanishing Verse depends on it; otherwise use a triome or surveil/tapped land if no instant answer is required.

- Turn 1 deviation preserves life only when tempo is safe. Shock lands may enter tapped if no turn-two removal or fixer is needed, but take the damage when the untapped land unlocks Lightning Helix, Abrupt Decay, Vanishing Verse, Sylvan Caryatid, or Up the Beanstalk against a fast start.

- Turn 2 should cast Sylvan Caryatid or Ancient Cornucopia when the board is not demanding removal. Prefer the mana bridge over Up the Beanstalk if it enables turn-three Bring to Light setup or stabilizes colors; cast Lightning Helix, Abrupt Decay, Vanishing Verse, or Leyline Binding instead when a visible threat will snowball before turn three.

- Turn 2 deviation uses Up the Beanstalk when mana is already stable and pressure is low. It is strongest before Leyline Binding, Bring to Light, Beza, the Bounding Spring, Overlord of the Hauntwoods, or Niv-Mizzet Reborn; it is too slow when the opponent has lethal pressure developing and removal is legal.

- Turn 3 should either answer the board or prepare the decisive turn-four spell. Use Leyline Binding, Maelstrom Pulse, Deafening Clarion, Culling Ritual, Lightning Helix, Abrupt Decay, or Vanishing Verse if visible permanents threaten the life total or engine; otherwise cast Up the Beanstalk plus a cheap answer, Ancient Cornucopia, Professor Dellian Fel, or Valki, God of Lies if legal and tactically relevant. Card text check required for Professor Dellian Fel exact tactical use.

- Turn 3 deviation holds Bring to Light setup when colors are incomplete. Prioritize land sequencing and mana fixing over a low-impact spell if the next turn can unlock Bring to Light for a stabilizer, Omnath, Locus of Creation value, or Niv-Mizzet Reborn pressure.

- Turns 4-5 are the main pivot from survival to advantage. Cast Bring to Light for the best legal bullet based on visible state, deploy Omnath, Locus of Creation before a land drop when landfall value is exposed, or resolve Niv-Mizzet Reborn when the board is stable enough to spend a turn drawing into multicolor resources.

- Turns 4-5 deviations favor removal over payoff when behind. Beza, the Bounding Spring, Deafening Clarion, Culling Ritual, Maelstrom Pulse, Leyline Binding, Lightning Helix, and Vanishing Verse can matter more than Niv-Mizzet Reborn if the opponent's battlefield threatens lethal or forces bad blocks; Card text check required for Beza, the Bounding Spring exact mode assumptions.

- Late game should chain engines without exposing a dead turn. Use Bring to Light, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Up the Beanstalk triggers, and Yorion, Sky Nomad only through legal actions that improve the current board or refill resources; Card text check required for Niv-Mizzet, Supreme and Overlord of the Hauntwoods exact ability timing.

- Late-game deviations protect against overextension. Hold extra payoffs when the current battlefield already wins through visible attacks, keep instant-speed Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Kolaghan's Command, or Dovin's Veto available when the opponent represents a comeback, and use Fabled Passage with Omnath, Locus of Creation only when legal sequencing rewards the landfall timing.

## Card Roles
- Sylvan Caryatid is the cleanest turn-two bridge from tapped five-color lands into Bring to Light, Omnath, Locus of Creation, and Niv-Mizzet Reborn. Cast it over Up the Beanstalk when colors are incomplete, when the hand has four- and five-mana payoffs, or when blocking a small attacker will preserve life; avoid treating it as expendable in combat unless the game is about immediate survival.

- Ancient Cornucopia is both fixing and stabilization, but its exact life-gain timing needs rules-engine confirmation at runtime. Card text check required for exact counter and life-gain behavior; tactically, cast it early when the hand needs durable five-color access, and prioritize it below immediate removal when a visible creature will force a dangerous tempo loss.

- Up the Beanstalk is the value engine that turns the deck's expensive interaction and payoff spells into sustained cards. Deploy it before Leyline Binding, Bring to Light, Beza, the Bounding Spring, Overlord of the Hauntwoods, or Niv-Mizzet Reborn when pressure is low; hold or skip it when the legal removal spell prevents lethal, protects the planes of combat, or keeps Bring to Light alive as the next stabilizer.

- Bring to Light is the toolbox pivot, not just a generic five-mana threat. Use it to find the legal card that answers the visible problem first: Deafening Clarion or Culling Ritual against go-wide boards, Maelstrom Pulse against clustered permanents, Kolaghan's Command when its modes line up, Valki, God of Lies when the opponent's hand is the key axis, Omnath, Locus of Creation or Niv-Mizzet Reborn when the board is stable, and Ultima only after verifying legal target and text requirements.

- Leyline Binding is the highest-leverage interaction because it can answer many permanent types while triggering Up the Beanstalk. Sequence domain lands and Fabled Passage to reduce its cost, but do not delay casting it for a discount when a visible permanent threatens lethal, a combo engine, or a snowballing battlefield; be careful against opponents who can remove enchantments and return the exiled permanent.

- Lightning Helix is early survival, reach, and life-buffer management. Use it aggressively against fast creatures and planeswalkers when legal, hold it against slower decks when instant-speed interaction or end-step pressure matters, and count the life gain as a tempo resource that buys time for Bring to Light and Niv-Mizzet Reborn rather than as a reason to take unnecessary shock-land damage.

- Vanishing Verse is premium clean interaction for monocolored threats and must be checked against target legality before assuming it answers anything. Prioritize it on permanents that dodge damage removal, carry snowballing static abilities, or pressure life totals quickly; avoid firing it into low-impact targets when Abrupt Decay, Lightning Helix, or Leyline Binding covers the same object with less strategic cost.

- Abrupt Decay is the efficient answer for cheap permanents and early engines. Use it to stop mana creatures, aggressive threats, hate permanents, and low-cost combo pieces when the target is legal; preserve it over Lightning Helix when the target is noncreature or damage-resistant, and preserve Leyline Binding when Abrupt Decay already handles the permanent cleanly.

- Niv-Mizzet Reborn is the main refill finisher and should be cast when the battlefield can absorb a five-mana value turn. Prioritize it after trading resources or after Up the Beanstalk has forced the opponent to answer multiple axes; avoid jamming it into a board where immediate removal, Beza, the Bounding Spring, Deafening Clarion, or Culling Ritual is required to survive.

- Omnath, Locus of Creation is a stabilizing value threat whose best timing depends on landfall sequencing. Cast it before making a land drop when legal and tactically safe, use Fabled Passage to maximize visible landfall opportunities, and do not expose it as a four-mana do-nothing when the opponent can punish the tapped-out window or when removal is required first.

- Niv-Mizzet, Supreme is a late-game pressure and resource card, but exact ability use requires text verification. Card text check required; treat it as a payoff for already-stable games, a Bring to Light consideration only when the legal line improves the current board, and a hold when the opponent's visible pressure demands immediate interaction.

- Professor Dellian Fel is a main-deck two-copy role-player that needs exact text verification before tactical automation. Card text check required; use legal actions involving Professor Dellian Fel only after confirming whether the visible board, available mana, and target requirements make the ability or body relevant, and do not rank it above known stabilizers without rules-engine support.

- Beza, the Bounding Spring is a catch-up bullet for games where the opponent is ahead on board, life, or cards. Card text check required for exact mode thresholds; prefer it when Bring to Light or natural casting produces immediate stabilization, and avoid it as a default value card when Niv-Mizzet Reborn or Omnath, Locus of Creation better converts a stable board into inevitability.

- Overlord of the Hauntwoods is a high-cost stabilizer or engine piece whose exact timing needs text verification. Card text check required; consider it when Up the Beanstalk is active or when a legal cast advances mana, board, or pressure, but avoid choosing it over immediate removal unless the visible state supports taking a setup turn.

- Valki, God of Lies is the hand-pressure or late-game modal threat that changes role based on available mana and legal face selection. Use the front side when early information and disruption matter, consider the back side only if the rules engine exposes it as legal and the game supports a high-mana commitment, and never assume hidden cards beyond revealed information.

- Kolaghan's Command is a flexible one-of that rewards waiting for modes that trade up. Use it when two legal modes both matter, such as removing a small creature while pressuring hand or recovering a threat; avoid spending it for a single low-impact mode unless tempo, lethal prevention, or a specific visible artifact demands action.

- Maelstrom Pulse is the broad sorcery-speed answer for problematic permanents and duplicate boards. Prioritize it when one card answers multiple visible copies or a permanent type other removal cannot cover; avoid sorcery-speed use before combat if instant-speed Lightning Helix, Abrupt Decay, Vanishing Verse, or Leyline Binding can preserve better flexibility.

- Culling Ritual is the reset button against low-cost permanent clusters and token-heavy starts. Use it only when the visible battlefield makes the exchange favorable or survival-critical, and account for your own Sylvan Caryatid, Up the Beanstalk, Ancient Cornucopia, or other cheap permanents before choosing it through Bring to Light.

- Deafening Clarion is the small-creature sweeper and life-race stabilizer. Card text check required for exact mode selection; prioritize it against wide aggressive boards, but avoid killing your own profitable blockers or missing larger threats when Leyline Binding, Vanishing Verse, or Maelstrom Pulse is the cleaner answer.

- Ultima is a powerful but text-sensitive one-of in the main deck and sideboard. Card text check required; choose it only when the legal targets, colors, timing, and visible payoff are explicit from the engine, and do not route Bring to Light toward it by name without confirming the runtime action text.

- Vibrant Outburst is a one-of that requires exact text verification before strategic reliance. Card text check required; treat it as a conditional tool rather than a default payoff, and use it only when the visible legal action explains why it improves mana, board, cascade-style sequencing, or card flow.

- Fabled Passage and the multicolor land suite are active spell enablers, not passive mana. Use Fabled Passage to unlock basics and domain for Leyline Binding, preserve fetch timing with Omnath, Locus of Creation when safe, and sequence Indatha Triome, Jetmir's Garden, Ketria Triome, Raugrin Triome, Spara's Headquarters, Xander's Lounge, Zagoth Triome, and Ziatora's Proving Ground to cover missing colors for Bring to Light and Niv-Mizzet Reborn.

## Interaction Priorities

- Priority: answer the permanent or spell that changes the next turn cycle before spending removal on ordinary damage. Use Leyline Binding, Vanishing Verse, Abrupt Decay, Lightning Helix, Maelstrom Pulse, Culling Ritual, Deafening Clarion, Kolaghan's Command, and Bring to Light only through legal engine actions, and let target legality decide which answer is real before ranking the line.

- Removal order: kill mana engines, combo enablers, snowballing card-advantage permanents, and lethal attackers before medium-sized creatures. Abrupt Decay should take cheap engines or hate permanents when legal, Lightning Helix should preserve life against early creatures, Vanishing Verse should cover monocolored threats that damage or Decay cannot cleanly handle, and Leyline Binding should be saved for the widest class of problematic permanents unless tempo demands immediate exile.

- Exile priority: use Leyline Binding or Vanishing Verse on threats that recur, dodge damage, invalidate blockers, or demand clean removal. Do not spend Leyline Binding on a small creature when Lightning Helix or Abrupt Decay is legal and sufficient; do spend it when the visible object is otherwise likely to dominate the battlefield or unlock the opponent's engine.

- Sweeper priority: choose Deafening Clarion or Culling Ritual only when the exchange improves survival, mana, or board position after counting your own Sylvan Caryatid, Ancient Cornucopia, Up the Beanstalk, and smaller permanents. Culling Ritual is best against clustered low-cost permanents or token-like boards; Deafening Clarion is best against creature pressure that damage-based sweeping can actually contain. Card text check required for exact Deafening Clarion mode handling.

- Discard priority: use Kolaghan's Command discard modes or Valki, God of Lies only when the legal action gives meaningful pressure on a hand, protects a future Bring to Light turn, or disrupts a known plan from revealed information. Do not assume hidden cards; if no card is revealed or selected by the engine, treat discard as a tempo choice rather than a guaranteed answer.

- Counter priority: when Dovin's Veto is sideboarded, counter the spell that invalidates your stabilizing turn, wins immediately, removes your only payoff, or stops Bring to Light from resolving. Bait permission or removal with Up the Beanstalk, Ancient Cornucopia, Omnath, Locus of Creation, or smaller interaction before committing Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Sphinx's Revelation, Surrak Dragonclaw, or a decisive Bring to Light when the matchup rewards patience.

- Bounce priority: this registered list has no default bounce plan to assume. If Ultima, Vibrant Outburst, or another legal runtime action presents a bounce-like choice, Card text check required; choose it only when the visible action text and board state prove it protects life, resets a key permanent, or clears lethal.

- Ignore priority: ignore low-impact creatures when life is high, blockers are stable, and the opponent's engine is a more important target. Ignore expendable permanents if answering them spends the only Leyline Binding or Vanishing Verse and leaves no answer for a larger visible threat.

- Archetype shift: against aggro, trade cards for life and board immediately; against control, preserve threat density and fight over Bring to Light, Niv-Mizzet Reborn, Up the Beanstalk, and Sphinx's Revelation; against combo, prioritize discard, Dovin's Veto, Unmoored Ego, and fast pressure; against graveyard decks, value Rest in Peace over marginal spot removal; against artifacts or enchantments, check Erode text and use Abrupt Decay, Maelstrom Pulse, Kolaghan's Command, or Leyline Binding according to legality and urgency.

## Combat And Trading Rules

- Combat rule: this deck wins by surviving into larger multicolor value, so block to preserve life when the next turn unlocks Bring to Light, Niv-Mizzet Reborn, Omnath, Locus of Creation, Beza, the Bounding Spring, or a sweeper. Do not race automatically; race only when visible pressure from Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Surrak Dragonclaw, Tolsimir, Friend to Wolves, or Beza, the Bounding Spring is already better than stabilizing.

- Engine preservation: protect Sylvan Caryatid, Ancient Cornucopia, and Up the Beanstalk when they are enabling colors, life, or card flow that the hand cannot replace. Trade them away only if the rules engine offers a legal line and the trade prevents lethal, preserves a key planeswalker-like permanent if present, or makes a sweeper or Bring to Light turn possible.

- Attack rule: attack with large creatures when the crack-back is contained by life total, blockers, or removal. Niv-Mizzet Reborn should usually pressure once it has refilled resources, but keep it home when blocking is required to reach another stabilizing turn; Omnath, Locus of Creation should attack only when landfall, blockers, and visible opposing damage make the race favorable.

- Block rule: trade expendable bodies for threats that shorten the clock below two turns, carry combat snowball text, or force bad use of Leyline Binding later. Prefer blocking over taking damage once life is near burn or alpha-strike range; preserve a high-value creature when Lightning Helix, Vanishing Verse, Abrupt Decay, Maelstrom Pulse, Deafening Clarion, or Culling Ritual can answer the attacker before damage.

- Life thresholds: above 12 life, spend turns developing colors and engines if the opponent has no immediate lethal setup; from 8 to 12, favor Lightning Helix, Beza, the Bounding Spring, Omnath, Locus of Creation sequencing, and clean blocks; below 8, treat every untapped attacker, burn-like spell, and haste-like legal action as urgent unless the engine shows no relevant threat.

- Protection rule: do not expose Niv-Mizzet Reborn or Niv-Mizzet, Supreme into obvious removal if a lower-value spell can draw interaction first. Use Up the Beanstalk, Ancient Cornucopia, Omnath, Locus of Creation, Professor Dellian Fel, or Valki, God of Lies as pressure or bait when the hand contains a stronger follow-up and the visible board allows the delay. Card text check required before relying on Professor Dellian Fel combat impact.

- Archetype differences: against aggro, block early and trade down to protect life; against midrange, trade only when it sets up a higher-impact refill; against control, attack with resilient pressure while holding back redundant threats; against combo, attack more aggressively once disruption has been used; against creature swarms, avoid piecemeal trades when Deafening Clarion or Culling Ritual is likely to reset the board.

## Selection And Tutor Rules

- Bring to Light rule: treat Bring to Light as the deck's main strategic selector, not as a generic value spell. Before casting it, count available colors, visible pressure, opponent mana, and the problem to solve; choose the legal searched card that answers the current board or creates the highest-stability next turn, and do not assume a target is available unless the engine exposes it.

- Bring to Light survival targets: find Lightning Helix, Vanishing Verse, Abrupt Decay, Maelstrom Pulse, Deafening Clarion, Culling Ritual, Leyline Binding, Beza, the Bounding Spring, or Tolsimir, Friend to Wolves only when the legal search/cast line directly improves survival or removes a visible permanent. Card text check required for exact Ultima, Vibrant Outburst, Erode, Beza, the Bounding Spring, and Tolsimir, Friend to Wolves effects before treating them as answers.

- Bring to Light advantage targets: find Niv-Mizzet Reborn, Omnath, Locus of Creation, Niv-Mizzet, Supreme, Sphinx's Revelation, Unmoored Ego, or Surrak Dragonclaw only when the board is stable enough that a slower payoff matters. Against control or combo, a protected Bring to Light for Dovin's Veto-adjacent plans is impossible because Dovin's Veto is not a legal Bring to Light target unless the rules engine says otherwise; use visible legal options only.

- Niv-Mizzet Reborn selection: when Niv-Mizzet Reborn reveals choices, prioritize cards that fill missing roles before raw quantity. Take removal if behind, Bring to Light if stable and mana-rich, Lightning Helix or Beza, the Bounding Spring if life is pressured, Leyline Binding or Vanishing Verse for clean exile, Omnath, Locus of Creation or Up the Beanstalk for resource snowballing, and Dovin's Veto or Unmoored Ego post-board only when the matchup and visible stack/hand information make interaction more important than board development.

- Fabled Passage timing: use Fabled Passage before color-critical spells when the fetched land unlocks Bring to Light, Leyline Binding discount, Omnath, Locus of Creation sequencing, or an immediate interaction spell. Delay Fabled Passage when Omnath, Locus of Creation is likely to enter soon and the extra landfall trigger matters more than current fixing.

- Land selection: fetch or choose lands to maximize five-color access while preserving untapped sources for the current turn. Favor basic Forest or other green access when Sylvan Caryatid or early fixing is missing; favor missing domain colors for Leyline Binding and Bring to Light; avoid taking a tapped Triome or Verge if the current turn requires Lightning Helix, Abrupt Decay, Vanishing Verse, or Dovin's Veto.

- Up the Beanstalk sequencing: deploy Up the Beanstalk before five-mana and high-mana plays when the tempo loss is survivable, because Bring to Light, Niv-Mizzet Reborn, Leyline Binding under some costs, Overlord of the Hauntwoods, and other large spells may convert into extra cards if rules text supports it. Card text check required for exact trigger handling.

- Bottom/filter rule: when scry, surveil, reveal, or selection prompts appear from legal actions, keep lands only when they unlock missing colors, Omnath, Locus of Creation landfall, or a needed fifth mana. Bottom redundant tapped lands, slow threats, or narrow answers when the visible board demands immediate interaction.

## Priority And Stack Rules

- Priority rule: pass priority when the stack is empty, life is stable, and no legal instant-speed action improves the visible board. Hold Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Kolaghan's Command, Dovin's Veto, Erode, and Sphinx's Revelation for windows where the target, spell, or end-step timing is visible and strategically justified.

- Response rule: answer the spell or ability that beats the current plan, not the first legal object. Use Dovin's Veto on noncreature spells that stop Bring to Light, remove the only payoff, create an immediate combo kill, or invalidate stabilization; use removal on creatures or permanents before damage, before a sacrifice/activation gains value, or before a key engine resolves when legal.

- Let-resolve rule: let low-impact spells resolve when the hand contains higher-value interaction and the visible board does not create lethal or a snowball. Do not spend Vanishing Verse or Leyline Binding on a minor permanent if Abrupt Decay, Lightning Helix, Maelstrom Pulse, Deafening Clarion, or Culling Ritual can cover the same battlefield class later.

- Tap-out gate: tap out for Bring to Light, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Surrak Dragonclaw, or Sphinx's Revelation only after checking visible opponent mana, known revealed cards, current clock, and whether waiting with interaction is safer. If waiting risks lethal or losing the window to stabilize, commit the payoff.

- Optional payment rule: accept optional payments or triggers only when they increase survival, card flow, or pressure without preventing required interaction. Decline any optional cost that spends mana needed for Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Dovin's Veto, or a visible tax/payment prompt.

- Combat window rule: use Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Kolaghan's Command, Deafening Clarion, or Culling Ritual before combat damage when the legal line saves life, protects a key blocker, or prevents a combat trigger. After blockers, reassess whether removal creates a better trade than preserving it for a larger permanent.

- Graveyard/recursion timing: use Rest in Peace as early as legal against graveyard-reliant opponents when it does not strand your own immediate plan, and do not wait for maximum value if the opponent can convert graveyard cards first. Card text check required before relying on Niv-Mizzet, Supreme, Kolaghan's Command, or other graveyard-related lines.

- End-step rule: cast Sphinx's Revelation, Lightning Helix to face, Kolaghan's Command, or other instant-speed value at the opponent's end step only when holding mana through their turn had purpose and no higher-priority response was needed. Main-phase them only when mana, life, landfall, or a required follow-up makes the timing necessary.

## Sideboard Map

- Sideboard posture: preserve the five-color engine, green setup, and enough high-impact multicolor cards for Niv-Mizzet Reborn while changing the narrow interaction package. Do not reduce Fabled Passage, Sylvan Caryatid, Ancient Cornucopia, or the broad land mix unless a registered plan explicitly proves the mana still casts Bring to Light, Leyline Binding, Omnath, Locus of Creation, and post-board sideboard cards.

Vs spell-based control or noncreature combo
Side in: 4 Dovin's Veto; 1 Unmoored Ego; 1 Sphinx's Revelation; 1 Surrak Dragonclaw
Cut: 1 Deafening Clarion; 1 Culling Ritual; 2 Abrupt Decay; 1 Maelstrom Pulse; 2 Lightning Helix

Vs graveyard-centric decks
Side in: 2 Rest in Peace; 1 Unmoored Ego; 1 Dovin's Veto
Cut: 1 Culling Ritual; 1 Deafening Clarion; 1 Maelstrom Pulse; 1 Professor Dellian Fel

Vs low-toughness creature decks
Role adjustment: prioritize Kaervek, the Spiteful; Tolsimir, Friend to Wolves; and Ultima when the sideboard interface exposes a legal registered plan for small-creature pressure, but do not execute a swap unless the generated IN/OUT cards preserve the registered deck.

Vs artifact, enchantment, or permanent-engine decks
Side in: 1 Erode; 1 Ultima; 1 Dovin's Veto
Cut: 1 Deafening Clarion; 1 Lightning Helix; 1 Professor Dellian Fel

- Dovin's Veto role: bring Dovin's Veto against control, combo, planeswalker-heavy, sweepers-plus-card-draw, and noncreature engines where stopping the key spell matters more than creature removal. It is bad against creature-dense decks that pressure life while presenting few noncreature spells worth holding two mana for. Its role changes from pure protection to proactive denial when defending Bring to Light, Niv-Mizzet Reborn, Omnath, Locus of Creation, Sphinx's Revelation, or a resolved Up the Beanstalk engine from visible stack interaction.

- Unmoored Ego role: bring Unmoored Ego against decks built around one named payoff, one combo card, or a small number of irreplaceable threats when public information, matchup knowledge, or revealed cards identify the correct name. It is bad against broad midrange decks where naming one card does not affect the visible battlefield or current resource exchange. Treat Bring to Light into Unmoored Ego as a commitment gate, not a default line, because spending a turn on hand/library disruption is weak if lethal pressure or a must-answer permanent is already visible.

- Rest in Peace role: bring Rest in Peace against graveyard recursion, delve, escape, reanimation, sacrifice loops, and decks whose threats shrink or vanish without graveyard access. It is bad when the opponent uses the graveyard only incidentally and when your immediate hand needs Kolaghan's Command or Niv-Mizzet, Supreme graveyard text; card text check required before assuming your own cards are impaired. Deploy it early when the opponent can convert graveyard cards immediately, and delay only when a current legal removal spell prevents lethal or protects the engine better.

- Kaervek, the Spiteful role: bring Kaervek, the Spiteful against small-creature decks, token swarms, one-toughness utility creatures, and boards where a static shrink effect changes combat math. It is bad against large-creature midrange, spell combo, and control with few bodies. Card text check required for exact static effect details, but tactically treat it as a board-shaping card that makes Lightning Helix, Deafening Clarion, Culling Ritual, Vanishing Verse, and combat blocks more favorable.

- Erode role: bring Erode against artifact or enchantment engines, high-impact permanents, and decks where an extra answer class is required beyond Abrupt Decay, Maelstrom Pulse, Vanishing Verse, and Leyline Binding. It is bad when the opponent presents mostly creatures, instants, sorceries, or threats already covered by main-deck interaction. Card text check required before relying on exact target type, mana value, exile, or replacement effects; choose it only when legal action text confirms the permanent class it answers.

- Ultima role: bring the sideboard Ultima when the matchup rewards an additional expensive catch-up spell, hard reset, or broad answer and the mana is likely to reach the required colors. It is bad against fast decks where early removal and life gain matter more than a slow card, and against permission decks if tapping out into open mana loses the window. Card text check required for exact effect, target rules, and timing, so never treat Ultima as removal, sweeper, or finisher unless the rules engine exposes the legal action and targets.

- Sphinx's Revelation role: bring Sphinx's Revelation against control, slow midrange, and attrition mirrors where holding interaction and converting unused mana into life/cards is decisive. It is bad against combo when shields must stay up for Dovin's Veto or Unmoored Ego, and against aggro when the game may end before a large instant matters. Its role changes from end-step card draw to stabilization if life total is under pressure and the engine exposes a legal life-gain cast.

- Surrak Dragonclaw role: bring Surrak Dragonclaw against blue control, counterspell-heavy decks, and flash-speed mirrors where resolving threats through permission matters. It is bad against removal-heavy creature decks that ignore counter wars and against fast aggro where a five-mana creature does not stabilize immediately. Card text check required for exact abilities, but tactically use it as a protected threat or threat-enabler only when visible mana and stack context make a counter-fight likely.

- Tolsimir, Friend to Wolves role: bring Tolsimir, Friend to Wolves against creature decks where a body, life buffer, and fight-style battlefield impact can swing stabilization. It is bad against control, combo, and large threats that make a small fight line ineffective. Card text check required for exact token, life, and fight handling; choose Tolsimir only when the legal action text shows it improves the current creature exchange or life race.

- Yorion, Sky Nomad role: register Yorion, Sky Nomad as the companion when the rules engine offers legal companion handling for this 80-card deck, and use it as a long-game resource source when hand pressure is low. It is bad as a main plan against fast decks if spending mana on companion access prevents interaction. Card text check required for exact companion and blink timing; do not board it into the main deck unless the sideboarding rules explicitly require that zone change.

- Aggro rule: Add role cards: Kaervek, the Spiteful; Tolsimir, Friend to Wolves; Ultima when legal text proves it stabilizes; selective Dovin's Veto only against burn or noncreature payoffs. Reduce main-deck emphasis: Valki, God of Lies, Niv-Mizzet, Supreme, slow selection, and interaction that misses visible attackers.

- Control rule: Add role cards: Dovin's Veto, Sphinx's Revelation, Surrak Dragonclaw, Unmoored Ego, and sometimes Yorion, Sky Nomad companion value. Reduce main-deck emphasis: Deafening Clarion, Culling Ritual, Abrupt Decay, excess Lightning Helix, and creature-only battlefield answers.

- Midrange rule: Add role cards: Sphinx's Revelation for attrition, Tolsimir, Friend to Wolves for creature mirrors, Dovin's Veto for planeswalkers or sweepers, and Ultima only when its legal text answers the board. Reduce main-deck emphasis: narrow removal that misses the opponent's best threat class and slow threats that do not win through visible pressure.

- Combo rule: Add role cards: Dovin's Veto, Unmoored Ego, Rest in Peace when the graveyard is part of the engine, and Surrak Dragonclaw only if counter wars define the matchup. Reduce main-deck emphasis: creature sweepers, life-gain-only plays, and expensive battlefield cards that do not disrupt the known combo turn.

## Matchup Guidance
- Aggro: Prioritize survival turns over maximum card count, because this deck wins aggro matchups by turning early removal and life gain into a stabilized five-color value engine. Keep hands with untapped or fetchable early colors for Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Sylvan Caryatid, or Ancient Cornucopia; do not keep a slow triome-heavy hand just because it contains Bring to Light or Niv-Mizzet Reborn. Use Lightning Helix on real damage sources rather than saving it for a larger target if the visible clock is short. Add role cards: Kaervek, the Spiteful; Tolsimir, Friend to Wolves; Ultima only when legal text proves it catches up; Dovin's Veto only when the aggro deck has burn, pump, or noncreature finishers. Reduce main-deck emphasis: Valki, God of Lies, slow Niv-Mizzet, Supreme lines, excess Up the Beanstalk setup, and removal that misses current attackers.

- Control: Protect threat resolution and avoid walking Bring to Light or Niv-Mizzet Reborn into obvious open interaction without a reason to force the exchange. Sequence lands to represent multiple colors, develop Up the Beanstalk early when it is legal and low-risk, and make the opponent answer repeated card-advantage permanents rather than one expensive spell. Use Bring to Light as a flexible pressure or answer tool after checking visible stack context, known cards, and whether Dovin's Veto can cover the exchange. Add role cards: Dovin's Veto; Sphinx's Revelation; Surrak Dragonclaw; Unmoored Ego; Yorion, Sky Nomad as companion value when available. Reduce main-deck emphasis: Deafening Clarion, Culling Ritual, some Lightning Helix, and creature-only answers with no visible targets.

- Combo: Disrupt the enabling card before racing, because Niv to Light is powerful but not naturally faster than dedicated combo. Mulligan toward Dovin's Veto, Unmoored Ego access, early pressure plus interaction, or Bring to Light when it can legally find the relevant disruption. Use Unmoored Ego only when matchup knowledge, public information, or revealed cards identify a high-confidence card name; do not name a speculative hidden card when a visible permanent or stack spell must be answered now. Add role cards: Dovin's Veto; Unmoored Ego; Rest in Peace for graveyard combo; Surrak Dragonclaw only for counter-fight combo. Reduce main-deck emphasis: Deafening Clarion, Culling Ritual, life-gain-only lines, and expensive tap-out threats that do not change the combo turn.

- Tempo: Trade mana efficiently and deny the opponent clean windows to punish tapped lands. Fetch or play lands so Lightning Helix, Abrupt Decay, Vanishing Verse, and Leyline Binding can operate before committing Bring to Light. Do not spend turn three or four on Up the Beanstalk if the visible board plus open mana suggests a threat will snowball through a pass. Add role cards: Dovin's Veto against permission or bounce-heavy builds; Surrak Dragonclaw against counterspell-heavy tempo; Kaervek, the Spiteful when their pressure is small creatures. Reduce main-deck emphasis: slow Niv-Mizzet Reborn hands without cheap interaction, Valki, God of Lies when it cannot safely affect the hand, and clunky sorcery-speed answers into open mana.

- Midrange: Play to out-scale one-for-one trades with Up the Beanstalk, Bring to Light, Niv-Mizzet Reborn, Omnath, Locus of Creation, and Yorion, Sky Nomad if companion access is legal. Remove threats that pressure life total or planeswalker-like value first, then pivot to haymakers once the battlefield is contained. Kolaghan's Command, Maelstrom Pulse, Vanishing Verse, Abrupt Decay, Leyline Binding, and Lightning Helix should be matched to the target class that leaves the fewest stranded answers later. Add role cards: Sphinx's Revelation; Tolsimir, Friend to Wolves; Dovin's Veto if they rely on noncreature closers; Ultima if legal text confirms broad impact. Reduce main-deck emphasis: narrow dead removal and expensive threats that are poor into the visible answer pattern.

- Big mana: Pressure their setup while preserving answers for the first payoff, because pure resource trading often favors the opponent once both decks reach high mana. Bring to Light should favor disruption, exile answers, or a payoff that immediately matters rather than a decorative value line. Use Unmoored Ego when the archetype depends on a small number of payoff names and public information supports the name. Add role cards: Dovin's Veto; Unmoored Ego; Sphinx's Revelation for slow mirrors; Erode only when artifacts or enchantments are central. Reduce main-deck emphasis: small sweepers, Kaervek, the Spiteful, and removal that cannot answer large threats.

- Graveyard: Deploy Rest in Peace before the opponent converts graveyard resources when it is legal and does not sacrifice immediate survival. Treat Rest in Peace as a strategic commitment that may affect Kolaghan's Command or Niv-Mizzet, Supreme; Card text check required for exact self-synergy costs. Use Leyline Binding, Vanishing Verse, and Maelstrom Pulse on threats already present if waiting for graveyard hate risks lethal. Add role cards: Rest in Peace; Dovin's Veto for reanimation or graveyard payoff spells; Unmoored Ego for a single critical graveyard payoff. Reduce main-deck emphasis: slow discard and engines that do not interact before the graveyard turn.

- Artifact/enchantment: Keep answer diversity high and do not spend Abrupt Decay, Maelstrom Pulse, Vanishing Verse, Leyline Binding, or Erode on a low-impact permanent if a known engine piece is likely or already visible. Culling Ritual can be a catch-up card only if legal text and the board show it meaningfully changes the permanent count; Card text check required before assuming mana or destruction details. Add role cards: Erode; Dovin's Veto against noncreature engines; Unmoored Ego for a single centerpiece. Reduce main-deck emphasis: Lightning Helix and creature sweepers when they do not answer the engine.

- Go-wide: Stabilize by reducing total damage, not by preserving spot removal for perfect targets. Deafening Clarion, Culling Ritual, Kaervek, the Spiteful, Lightning Helix, Tolsimir, Friend to Wolves, and Beza, the Bounding Spring are the cards to evaluate first when legal actions show a board reset, shrink, life buffer, or favorable combat swing. Do not attack with necessary blockers unless the crack-back is clearly contained by visible removal or life gain. Add role cards: Kaervek, the Spiteful; Tolsimir, Friend to Wolves; Ultima if legal text confirms a reset. Reduce main-deck emphasis: Valki, God of Lies and slow five-mana value without immediate board effect.

- Single-threat: Preserve exile or unconditional answers for the threat that matters. Vanishing Verse, Leyline Binding, Maelstrom Pulse, Abrupt Decay, and Bring to Light for the right answer are higher priority than incremental value while one large creature, planeswalker-like permanent, or protected attacker defines the board. Use Lightning Helix only if it actually removes the threat or changes the race. Add role cards: Dovin's Veto for noncreature threat decks; Erode if the threat is artifact/enchantment based; Unmoored Ego if one named card defines the deck. Reduce main-deck emphasis: sweepers and Kaervek, the Spiteful unless small support creatures matter.

- Burn: Treat life total as a resource with a floor, not an abstract buffer. Lightning Helix, Omnath, Locus of Creation, Ancient Cornucopia, Beza, the Bounding Spring, Tolsimir, Friend to Wolves, and Sphinx's Revelation are stabilizing cards when legal text and timing produce life or blockers; Card text check required for exact life-gain triggers on newer cards. Dovin's Veto should counter burn or card-advantage spells that represent multiple damage, not minor setup. Add role cards: Dovin's Veto; Tolsimir, Friend to Wolves; Sphinx's Revelation if the game can reach it. Reduce main-deck emphasis: painful mana choices, slow discard, and tap-out haymakers without life impact.

- Removal-heavy: Do not overcommit creatures into a hand that is visibly trading one-for-one unless the next threat creates immediate card advantage. Up the Beanstalk, Bring to Light, Niv-Mizzet Reborn, Omnath, Locus of Creation, Overlord of the Hauntwoods, Sphinx's Revelation, and Yorion, Sky Nomad are the cards that punish exhausted removal. Sylvan Caryatid and Ancient Cornucopia should be valued as mana stability rather than combat resources. Add role cards: Sphinx's Revelation; Dovin's Veto against sweepers or premium removal; Surrak Dragonclaw against counter-removal shells. Reduce main-deck emphasis: low-impact spot removal that has no visible target and fragile threats without value on resolution.

## Specific Matchup Notes

- General/archetype-only notes: Treat all matchup labels as assumptions until public cards identify the opponent. Revealed cards, legal actions, graveyards, exile, mana, and visible threats override archetype guesses; use these notes to rank priorities, not to invent hidden cards.

- Aggro and burn: Prioritize life-preserving lines before card-advantage lines when the visible clock is short. Lightning Helix, Leyline Binding, Vanishing Verse, Abrupt Decay, Deafening Clarion, Omnath, Locus of Creation, Beza, the Bounding Spring, Ancient Cornucopia, and Bring to Light for a stabilizer are the key runtime checks. Add role cards: Tolsimir, Friend to Wolves; Sphinx's Revelation; Dovin's Veto against noncreature damage or draw spells; Kaervek, the Spiteful against small-creature pressure. Reduce main-deck emphasis: Valki, God of Lies, slow Niv-Mizzet Reborn lines, and tap-heavy mana that spends life without stabilizing.

- Creature midrange: Trade early only when the exchange protects mana development or prevents snowballing damage. Preserve Bring to Light, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Up the Beanstalk, Overlord of the Hauntwoods, Omnath, Locus of Creation, and Yorion, Sky Nomad for the stage where both players have spent interaction. Add role cards: Tolsimir, Friend to Wolves; Sphinx's Revelation; Ultima if legal text confirms it answers the board; Dovin's Veto if public cards show noncreature haymakers. Reduce main-deck emphasis: narrow removal with no visible target class and speculative discard.

- Control and permission: Make land drops, force action on their end step when legal, and avoid tapping into open mana for a single threat unless waiting loses more. Dovin's Veto, Surrak Dragonclaw, Sphinx's Revelation, Bring to Light, Niv-Mizzet Reborn, Up the Beanstalk, Yorion, Sky Nomad, and Valki, God of Lies are the important pressure and counter-pressure cards. Add role cards: Dovin's Veto; Surrak Dragonclaw; Sphinx's Revelation; Unmoored Ego when public information identifies one decisive payoff. Reduce main-deck emphasis: creature sweepers, excess small removal, and Culling Ritual unless targets are visible.

- Big mana and combo: Disrupt the first payoff, not the least expensive setup card, unless the setup card is visibly the bottleneck. Bring to Light should find pressure, a named disruption effect, or an answer that changes the next turn; Unmoored Ego needs a public-information basis for the named card. Add role cards: Dovin's Veto; Unmoored Ego; Sphinx's Revelation in slow games; Erode against artifact or enchantment engines. Reduce main-deck emphasis: Lightning Helix, Kaervek, the Spiteful, and Deafening Clarion when they lack targets.

- Graveyard decks: Commit Rest in Peace when graveyard resources are central and the battlefield does not demand immediate removal first. Check self-impact before relying on Kolaghan's Command, Niv-Mizzet, Supreme, or any graveyard-adjacent line; Card text check required for exact self-synergy costs. Add role cards: Rest in Peace; Dovin's Veto; Unmoored Ego for a single graveyard payoff. Reduce main-deck emphasis: slow value lines that do not affect the graveyard turn.

- Artifact/enchantment shells: Save Abrupt Decay, Maelstrom Pulse, Vanishing Verse, Leyline Binding, Culling Ritual, Erode, and Bring to Light for the permanent that actually drives the board or resource engine. Add role cards: Erode; Dovin's Veto; Unmoored Ego if one centerpiece is publicly established. Reduce main-deck emphasis: Lightning Helix and creature-only stabilizers when the engine is noncreature.

## Risk Summary

- Mana risk: The deck needs five colors across an 80-card shell, so early hands with Fabled Passage, triomes, Verge lands, shock lands, Sylvan Caryatid, and Ancient Cornucopia must be judged by castability, not by raw land count. Do not keep a hand that cannot cast early interaction or mana fixing before the opponent's visible clock matters.

- Matchup risk: The deck can answer many permanent classes, but it can lose to drawing the wrong half. Use public information to decide whether Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Deafening Clarion, or Dovin's Veto is the answer to preserve.

- Draw risk: Up the Beanstalk, Bring to Light, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, and Sphinx's Revelation are powerful only if the game reaches their window. Under pressure, spend the turn on removal, life gain, or mana that enables multiple future spells.

- Over-sideboarding risk: Do not dilute the five-color value engine by adding narrow cards without a visible or highly likely target class. Rest in Peace, Erode, Unmoored Ego, Kaervek, the Spiteful, Surrak Dragonclaw, Tolsimir, Friend to Wolves, Dovin's Veto, Ultima, and Sphinx's Revelation each need a matchup reason.

- Graveyard risk: Rest in Peace may change access to graveyard-dependent value from Kolaghan's Command or Niv-Mizzet, Supreme; Card text check required before treating the self-impact as harmless. Play it anyway when the opponent's graveyard engine is the larger visible risk.

- Sweeper/removal risk: Culling Ritual, Deafening Clarion, Kaervek, the Spiteful, and Ultima should not be fired for cosmetic cleanup if spot removal handles the relevant threat. Conversely, do not spend every spot answer when a sweeper is the only route to stabilizing a wide board.

- Closer risk: Niv-Mizzet Reborn, Omnath, Locus of Creation, Overlord of the Hauntwoods, Professor Dellian Fel, Beza, the Bounding Spring, Yorion, Sky Nomad, and Surrak Dragonclaw can be stranded by poor timing or open interaction. Commit a closer when it stabilizes, generates value on resolution, or forces the opponent to answer under pressure.

- Interaction risk: Dovin's Veto, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Lightning Helix, Kolaghan's Command, and Bring to Light answer different problems. Match the answer to the threat type shown by the rules engine instead of using the cheapest legal action first.

- Sequencing risk: Fetch, shock, triome, Verge, Sylvan Caryatid, Ancient Cornucopia, Up the Beanstalk, and Bring to Light choices compound across turns. Sequence for the next two legal-spell windows, especially when holding Lightning Helix, Vanishing Verse, Leyline Binding, Omnath, Locus of Creation, or Bring to Light.

## Test Feedback Checklist

- Deciding factor: Record whether the match was decided by mana development, early survival, Bring to Light access, Niv-Mizzet Reborn card flow, Up the Beanstalk velocity, sideboard hate, or failure to close after stabilizing.

- Mulligans: Note whether kept hands had castable early plays through visible lands, Fabled Passage, Sylvan Caryatid, Ancient Cornucopia, and shock/triome sequencing, and flag any keep that lacked a path to Lightning Helix, Abrupt Decay, Vanishing Verse, or Leyline Binding before pressure mattered.

- Mana: Track every game where colors or tapped lands stranded Bring to Light, Omnath, Locus of Creation, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Deafening Clarion, Kolaghan's Command, or Culling Ritual, and record which land or fixer would have changed the line.

- Velocity: Check whether Up the Beanstalk, Bring to Light, Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Sphinx's Revelation, and Yorion, Sky Nomad generated enough cards before the opponent's clock forced purely defensive turns.

- Engine timing: Identify whether Up the Beanstalk was cast early enough to matter, whether Ancient Cornucopia or Sylvan Caryatid enabled double-spell turns, and whether Overlord of the Hauntwoods advanced the plan or consumed a turn without stabilizing.

- Removal use: Review whether Lightning Helix, Abrupt Decay, Vanishing Verse, Leyline Binding, Maelstrom Pulse, Deafening Clarion, Culling Ritual, Kolaghan's Command, Kaervek, the Spiteful, Tolsimir, Friend to Wolves, Erode, or Ultima answered the threat that actually mattered. Card text check required for Erode and Ultima before drawing firm conclusions about missed lines.

- Sideboard impact: Record whether Dovin's Veto, Rest in Peace, Unmoored Ego, Surrak Dragonclaw, Sphinx's Revelation, Kaervek, the Spiteful, Tolsimir, Friend to Wolves, Erode, Yorion, Sky Nomad, and sideboard Ultima matched the opponent's revealed plan or sat stranded.

- Closing: Note whether stabilized games were converted by Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Omnath, Locus of Creation, Overlord of the Hauntwoods, Professor Dellian Fel, Beza, the Bounding Spring, Yorion, Sky Nomad, Surrak Dragonclaw, or repeated Bring to Light pressure.

- Role: Mark each game where the pilot acted as control, tap-out midrange, toolbox answer deck, or threat-dense value deck, and record whether the chosen role matched visible pressure, open mana, and known opponent resources.

- Mistakes: Flag any action where the pilot used the cheapest legal spell instead of the correct answer, fetched a color that blocked the next two turns, passed with a relevant answer available, overcommitted into a visible sweeper risk, or delayed a stabilizer while life total was under pressure.

- Stranded cards: Track repeated stranded copies of Bring to Light, Leyline Binding, Lightning Helix, Vanishing Verse, Abrupt Decay, Up the Beanstalk, Omnath, Locus of Creation, Niv-Mizzet Reborn, Professor Dellian Fel, Vibrant Outburst, Valki, God of Lies, and sideboard cards.

- Overperformers and underperformers: Compare card mentions in wins and losses, especially Up the Beanstalk, Ancient Cornucopia, Bring to Light, Leyline Binding, Lightning Helix, Omnath, Locus of Creation, Beza, the Bounding Spring, Professor Dellian Fel, and Niv-Mizzet Reborn.

## First Tuning Questions

- Card quantities: If early games are lost before stabilization, should the main deck increase cheap survival density such as Lightning Helix, Abrupt Decay, Vanishing Verse, Deafening Clarion, or Beza, the Bounding Spring, or is the real failure tapped mana and slow keeps?

- Mana base: If Bring to Light, Omnath, Locus of Creation, Leyline Binding, or Niv-Mizzet Reborn are repeatedly stranded, should the balance among Fabled Passage, triomes, shock lands, Verge lands, Sylvan Caryatid, and Ancient Cornucopia change toward more reliable early color access?

- Aggro plan: If wide creature decks win despite removal, should Kaervek, the Spiteful, Tolsimir, Friend to Wolves, sideboard Ultima, Deafening Clarion, or Culling Ritual occupy more post-board emphasis, or are spot-removal decisions being spent on the wrong threats?

- Control plan: If permission decks beat the deck after stabilization, should Dovin's Veto, Surrak Dragonclaw, Sphinx's Revelation, Valki, God of Lies, Yorion, Sky Nomad, or more threat diversity receive greater emphasis, and should low-impact removal be reduced more aggressively in those matchups?

- Closing speed: If games stabilize but time out or get rebuilt against, should Niv-Mizzet Reborn, Niv-Mizzet, Supreme, Overlord of the Hauntwoods, Omnath, Locus of Creation, Professor Dellian Fel, Surrak Dragonclaw, or Yorion, Sky Nomad be adjusted as the preferred closing package?

- Toolbox tension: If Bring to Light often finds removal instead of a game-winning engine, is the deck missing a decisive searchable stabilizer, or is the pilot failing to commit Niv-Mizzet Reborn, Omnath, Locus of Creation, Beza, the Bounding Spring, or Sphinx's Revelation at the correct window?

- Sideboard slots: If Rest in Peace, Erode, Unmoored Ego, Kaervek, the Spiteful, Tolsimir, Friend to Wolves, Surrak Dragonclaw, Sphinx's Revelation, and Dovin's Veto are not affecting actual losses, which matchup class justifies each slot after reviewing logs?

- Role conflict: If Up the Beanstalk, Ancient Cornucopia, Bring to Light, and Niv-Mizzet Reborn pull toward slow value while Lightning Helix, Vanishing Verse, Abrupt Decay, and Deafening Clarion pull toward survival, should the configuration become more defensive or more threat-forward for the tested metagame?
