Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

  • Win condition: Fire King Xyz/Synchro/Link boards (Garunix Eternity, Jurrac Astero/Meteor, Promethean Princess) converting from a Fire King engine; Recursion-driven Fire King monster loops from the GY via Legendary Fire King Ponix, Kirin and Garunix
  • Turn 1 (going first): Open a Fire King starter (Ponix / Courtier Ulcanix / Island), search and build a Fire King board, protect it with Fire King Sanctuary / Island and hand traps
  • Turn 2 (going second): Use Droll & Lock Bird, Ash Blossom and Dominus Impulse to break the opponent's first interaction, then extend through Fire King recursion
  • Recovery: Fire King monsters destroyed by effect return from the GY (Garunix, Kirin, Ponix) to rebuild the engine
  • After siding: No side deck is registered, so no post-side plan can be evaluated

Why it scores here

The deck reliably opens its Fire King engine: 26 archetype-core copies give an estimated 99.5% chance of at least one core card in a 5-card opening hand, so starter access is strong (Inferred from hypergeometric draws). Its interaction package (3 Ash Blossom, 3 Dominus Impulse, 2 Droll & Lock Bird, Maxx "C", Ghost Ogre) gives it several layered answers, and Fire King recursion from the GY lets it keep rebuilding after one disruption. Converting into a closing board depends on Garunix Eternity, Jurrac Astero and Promethean Princess, but no recorded boards exist, so ceiling and median are text-only estimates with no measured floor. Popularity and guide mentions confirm the list is real and played, and they earned no points; no card scores were averaged. The score is capped low because the list runs 3 copies of a Semi-Limited card (legal limit 2), so this is a structural-only, theoretical read.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 72 P(>=1 archetype-core card in opening 5) ≈ 0.995; 3-copy starters at 32% each (Inferred)
D2 Opening-Hand Quality & Brick Management 60 7 hand traps and 9 searchers give non-dead hands, but several Fire King monsters are conditional on a second FIRE monster (Inferred)
D3 Combo Conversion & Ceiling 55 No parseable boards; ceiling read from card text on Garunix Eternity and Astero only (Inferred)
D4 Combo Floor & Median Output 45 No recorded boards, so median is unmeasured and the score is a text-based estimate (Inferred)
D5 Interruption Resilience & Route Redundancy 65 Recursion through Kirin, Garunix and Ponix plus 7 hand traps gives several independent lines after disruption (Inferred)
D6 Resource Economy, Recovery & Grind 60 GY-based recursion and searchers offset spend; no resource signature data (Inferred)
D7 End-Board & Interaction Quality 70 Dominus Impulse x3, Ash Blossom x3, Droll x2 and Maxx "C" give layered negation and draw answers (Verified card text, Inferred quality)
D8 Going-Second & Board-Breaking Power 62 Droll & Lock Bird and Ash Blossom answer going-second board starts; no going-second split data (Inferred)
D9 Offensive Pressure & Closing Power 55 Closing power rests on Garunix Eternity (3000 ATK) and Astero (2500 ATK), with few direct finishers in the list (Verified stats, Inferred)
D10 Main Deck Efficiency & Flexibility 50 42 main-deck cards with only 42% exact-name Fire King purity; 33 off-archetype copies dilute the engine (Verified composition)
D11 Extra Deck Efficiency & Coverage 55 15 Extra Deck cards split across Link, Synchro and one Xyz; several Synchro/Link cards are off-archetype (Verified composition, Inferred coherence)
D12 Side Deck Adaptability 15 No side deck is registered in the export, so post-side adaptability cannot be assessed (Provisional)
D13 Matchup Coverage & Format Fit 40 No tournament or dated meta data; the guide describes Fire King as weak against negate-heavy metas (Provisional)
D14 Pilotability & Error Tolerance 50 Multiple engine branches and Extra Deck summon routes raise decision load moderately (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*57 + 0.20*50 - 3 ≈ 52.6; capped at 30 because the deck is Illegal (copy limit exceeded), so this is a theoretical structural-only score

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Core Fire King engine is dense (26 copies) and reliably opens
  • Layered negation and draw answers (Ash Blossom, Dominus Impulse, Droll & Lock Bird, Maxx "C")
  • GY recursion lets the engine rebuild after disruption

Weaknesses

  • List is Illegal: Fire King High Avatar Kirin runs 3 copies against a legal limit of 2
  • Off-archetype dilution (Jurrac, Dominus, Salamangreat, Charmer, Kuriboh): only 42% exact-name purity
  • No side deck and no recorded boards, so the post-side and combo ceiling cannot be measured

Critical choke points

  • Fire King High Avatar Kirin copy limit: the deck is not playable as built until one copy is removed
  • Dependence on Garunix Eternity and Astero as the closing cards
Priority Remove Add Reason
1 1 copy of Fire King High Avatar Kirin a legal non-Limited card or none Brings the list back under the Master Duel copy limit so the deck can receive a normal score
2 off-archetype Extra Deck slots with weak synergy (review Enigmaster Packbit / Golden Cloud Beast) Fire King-aligned Extra Deck options Raises archetype purity and engine coherence (Inferred)

Evidence & confidence

  • Verified: Illegal status: Fire King High Avatar Kirin 3 copies vs legal 2; Main 42 and Extra 15 are inside Master Duel size rules; Archetype purity 42.1%; 26 core-archetype copies; Banlist statuses for Maxx "C", Droll & Lock Bird and Kirin
  • Inferred: Opening-hand starter access ≈ 0.99 (hypergeometric); Brick rate and hand-trap coverage; Ceiling and interaction quality from card text
  • Provisional: Meta Power (no dated metagame sample); Matchup fit and side adaptability
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no side deck registered — post-side adaptability unmeasured no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — brick, starter and matchup rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
