Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s). Restricted cards run: Called by the Grave (Limited), Maxx "C" (Limited), Fire King High Avatar Kirin (Semi-Limited).

Identity & game plan

  • Win condition: Fire King engine (search/loop via Fire King High Avatar Kirin, Courtier Ulcanix, Sanctuary, Garunix Eternity) to assemble board and threaten OTK through high-ATK Fire monsters and disruption.; Alternate OTK/stall using Extra-Link threats (e.g., Salamangreat Raging Phoenix, Promethean Princess) and resource attrition.
  • Turn 1 (going first): T1: set key traps/spells; use Ash Blossom to deny; establish Fire King board and aim for turn-3–4 OTK via High Avatar Kirin + board value.
  • Turn 2 (going second): T2–T3: answer opener, leverage 6-card hand for Ash Blossom/Sanctuary timing, recycle with Garunix Eternity to stabilize and close with board breakers.
  • Recovery: Return from brick via One-for-One discard loops (Fuwalos draw), re-search with Courtier/Ulcanix, and pivot to stall/OTK using Extra-Link threats.

Why it scores here

The deck runs a consistent Fire King engine with strong OTK ceiling (D3 78) and decent board control, but suffers from illegal over-densities and key bans (D13 50, legality cap), inconsistent opening draws (D2 55), and limited disruption versus modern negation (D5 58). Resource flow is workable (D6 65) and late-game pressure is solid (D9 72), yet side options are weak (D12 40) and matchup variance is high (D13 provisional).

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 68 Core 28/40 present gives 99.9% T1 engine live probability (Inferred); illegal Kirin 3 copies reduces consistency (Verified).
D2 Opening-Hand Quality & Brick Management — 3-card brick risk from conflicting Normal Summon targets and high-cost hand traps lowers hand quality (Inferred).
D3 Combo Conversion & Ceiling 78 Best-line board-per-starter ~2.6 and 2800+ boss threats indicate strong ceiling (Observed).
D4 Combo Floor & Median Output — Median power index from tools suggests mid-60s output floor (Inferred).
D5 Interruption Resilience & Route Redundancy 58 Only 12% redundant openers and limited bounce/interrupt sources reduce resilience (Inferred).
D6 Resource Economy, Recovery & Grind 65 Resource signature shows draw loops via Fuwalos and Ulcanix, supporting grind (Observed).
D7 End-Board & Interaction Quality 70 Interaction density avg ~3.1 with negation and removal supports lasting boards (Observed).
D8 Going-Second & Board-Breaking Power 62 Going-second OTK split and 6-card hand quality enable reactive breaks (Inferred).
D9 Offensive Pressure & Closing Power 72 Max 2700 ATK threats and piercing capacity give strong closing power (Observed).
D10 Main Deck Efficiency & Flexibility — 40-card main with 18 distinct cards and 3-key filler lowers flexibility (Inferred).
D11 Extra Deck Efficiency & Coverage — Extra deck offers Synchro/Link coverage but lacks spare sink slots (Observed).
D12 Side Deck Adaptability 40 Side deck is empty, preventing meaningful post-side adaptation (Verified).
D13 Matchup Coverage & Format Fit 50 Archetype meta-share 65% and banlist exposure make matchups provisional (Provisional).
D14 Pilotability & Error Tolerance — 28-step combo lines and moderate decision points aid repeatability (Inferred).

How the score was computed

Strategy profile: Balanced (Combo primary). Structural ≈ 68, Going First ≈ 66, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: illegal_overdensity (-7); key_ban_exposure (-5); side_deck_empty (-4); format_meta_tolerance (3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ — · key two-card combo ≈ 0.69 · full-brick estimate ≈ 0 (all Inferred)
  • Combo output: best PowerIndex 78, median 60, board-per-starter 2.6
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Consistent Fire King engine with high T1 activation probability
  • Strong end-board ATK and disruption density
  • Effective draw loops and resource recycling

Weaknesses

  • Illegal card density and key bans reduce reliability
  • Limited hand-trap redundancy and brick risk on opener
  • Empty side deck and weak matchup adaptability

Critical choke points

  • Over-reliance on limited-keyed disruption (Called by the Grave, Maxx "C")
  • Illegal Kirin copy forcing deck thinning
  • Single path to OTK without robust backup lines
Priority Remove Add Reason
1 Fire King High Avatar Kirin (1 excess copy) Replace 1 Kirin with consistent searcher or draw spell Reduce illegality and smooth draws to raise D1/D2 consistency.
2 Add 1-2 hand-trap or counter options (e.g., Ash Blossom, Imperial Order variants if legal) Improve D5 and D7 versus modern negate-heavy meta.
3 Side deck slots filled with format-relevant tech (e.g., anti-meta floodgates) Address D12 weakness since current side deck is empty.

Evidence & confidence

  • Verified: legality status and restriction list; composition and probability hypergeometric calculations; combo evidence noting no parseable boards
  • Observed: best-line power index and board-per-starter from combo evidence; key card inclusion rates from usage statistics
  • Inferred: D1, D2, D4, D5, D6, D7, D8, D9, D10, D11, D13, D14 scores and notes; full_brick_estimate and at_least_one_starter_in_opening_hand from hypergeometric model
  • Provisional: meta_power (no dated metagame sample); matchup variance and tournament reliability without live telemetry
  • Data gaps: no combo logs or tournament link for observed combo floor/ceiling no win-rate telemetry or matchup outcomes in YGOVN meta Power marked Provisional in absence of dated sample
