Legality

Main 57 / Extra 15 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

  • Win condition: Synchro-summon Red Dragon Archfiend / Scarred Dragon Archfiend and other Archfiend-family Synchros that attack through the field (Inferred from card text); Bystial and Mitsurugi Ritual/Synchro beatdown lines (Inferred)
  • Turn 1 (going first): Turn 1 Crimson Gaia or Crimson Call to search a Synchro-enabling Tuner, then Bone Archfiend or Power Vice Dragon into a Synchro (Inferred; no recorded boards)
  • Turn 2 (going second): Six-card hand with hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird) to answer the opponent's first summon or search, then rebuild through Resonator searchers (Inferred)
  • Recovery: Resonator and Archfiend searchers from the Deck and GY (Vision Resonator, Soul Resonator, Synkron Resonator, Mitsurugi no Mikoto Saji) to re-enter a Synchro after a board break (Inferred)
  • After siding: Not evaluable: side_count is 0, so there is no post-side plan

Why it scores here

The deck has a real Synchro engine: 14 core archetype copies give about a 0.77 chance of at least one in the opening five, and 22 searcher-text cards give about a 0.92 chance of a search-capable card in hand (Inferred from the hypergeometric table). Its 13 hand traps and 14 negation-text cards raise interaction and going-second resilience, which is why D7 and D8 score in the 60s-70s. Recorded combo data is absent, so ceiling and median are text-only inferences and score lower. The score is not driven by Archfiend popularity, and card scores were not averaged. The list is Illegal: three Forbidden or over-limit copy violations and a zero-card side deck cap the result at 25 and make it a structural-only read.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one archetype core in opening 5) = 0.77; 22 searcher-text cards; 2-card bootstrap plausible (Inferred)
D2 Opening-Hand Quality & Brick Management 55 21 singletons, 10 triple-copies, 26 Level-0 Spell/Trap cards; several narrow Mitsurugi/Resonator conflicts (Inferred)
D3 Combo Conversion & Ceiling 55 No parseable boards; ceiling is a text-only read of Synchro chains through Red Dragon Archfiend and Crimson Blade Dragon (Inferred)
D4 Combo Floor & Median Output 45 combos_evidence has 0 scored boards; median cannot be measured, only inferred from starter diversity (Inferred)
D5 Interruption Resilience & Route Redundancy 62 13 hand traps plus Resonator-based re-searches give multiple routes after one interruption (Inferred)
D6 Resource Economy, Recovery & Grind 58 22 searcher-text and 7 recursion-text cards support a resource rebuild; no net-advantage data (Inferred)
D7 End-Board & Interaction Quality 70 14 negation-text and 21 removal-text cards; Ash Blossom and Ghost Belle are quick-effect negates (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 62 P(hand trap in 6 cards going second) = 0.81; Crimson Gaia and Red Dragon Archfiend give some board-breaking reach (Inferred)
D9 Offensive Pressure & Closing Power 65 Red Dragon Archfiend 3000 ATK and Storm-Bane Dragon Destorbim 3000 ATK are the closers; Bystial Dis Pater and The Crimson King are absent (Verified card text, Inferred)
D10 Main Deck Efficiency & Flexibility 45 57 Main cards; exact archetype-name purity 8.3%; archetype_spread shows 33 generic and 12 sub-archetype sources (Verified composition)
D11 Extra Deck Efficiency & Coverage 60 15 Extra cards (12 Synchro, 2 Link, 1 XYZ) with access through Resonator and Crimson Gaia searches (Verified composition, Inferred access)
D12 Side Deck Adaptability 10 side_count is 0; no side deck to adapt (Verified)
D13 Matchup Coverage & Format Fit 45 tournament_context unavailable; archetype meta-share not supplied (Provisional)
D14 Pilotability & Error Tolerance 40 Multi-step Synchro lines with several Quick Effects and Resonator-to-Synchro sequencing (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: Illegal cap: Final = min(0.80*Structural + 0.20*TournamentReliability + ContextModifiers, 25); Meta Power provisional (null). Pre-cap = 0.80*57 + 0.20*42 - 12 = 41.7, capped to 25.

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.77 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Deep hand-trap suite (13 cards) for going second
  • Multiple searchers (22 text cards) and a Resonator chain for rebuilding
  • Varied Synchro and Link Extra Deck coverage with a solid closer package
  • Archfiend core in 14 copies gives a high chance of at least one core card in the opening five

Weaknesses

  • Illegal list: two Forbidden cards and three over-limit cards
  • No side deck
  • No recorded boards, so combo ceiling and median cannot be verified
  • Low archetype purity (8.3%) and 26 Level-0 Spell/Trap slots raise brick risk
  • Heavy reliance on Resonator-based Synchro sequencing

Critical choke points

  • Red Dragon Archfiend and Crimson Gaia: a single Gaia search line depends on a Synchro-enabling Tuner in hand
  • Hand-trap count drops sharply if the opponent wins the first summon
Priority Remove Add Reason
1 Ame no Habakiri no Mitsurugi and Triple Tactics Talent Legal replacements (e.g. one of the Archfiend or Resonator core cards) Forbidden cards make the list illegal; removing them is required before any normal score can apply
2 Two copies of Pre-Preparation of Rites and two of Mitsurugi Prayers Archfiend or Resonator searchers within the copy limit Each is over its OCG copy limit (1 allowed)
3 One copy of Ash Blossom & Joyous Spring Unrelated copy-legal card Semi-Limited allows 2 copies; the deck runs 3
4 Optional: one of the 26 Level-0 Spell/Trap slots Bystial Dis Pater or The Crimson King (absent core cards, usage 61% and 69%) Adds the missing archetype core closer; usage_statistics show both are commonly run
5 None A 10-15 card side deck Enables a post-side plan for best-of-3 play

Evidence & confidence

  • Verified: Legality: Illegal; 57 Main, 15 Extra, 0 Side; 5 copy/ban violations; Card text and banlist status for every listed card; Archfiend usage stats: 12 core cards, 7 present
  • Inferred: Opening-hand consistency: P(at least one core) = 0.77; Hand-trap coverage on going second: 0.81; Resonator-based recovery and Synchro sequencing; Interaction quality from card text
  • Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13)
  • Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and pilot records absent no win-rate telemetry for going-first/second, matchups, or brick/starter rates no side deck supplied: post-side plan cannot be evaluated deck title is null: identity taken from archetype and card list Meta Power is Provisional unless a dated metagame sample is supplied
