Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

  • Win condition: Magistus Fusion, Link and Xyz boards (Cosmo Queen, Zoroa the Magistus Verethragna, Magistus Chorozo, Invoked Mechaba) that break the board and attack for lethal; Fairy Tail beatdown through Fairy Tail - Luna, Fairy Tail - Snow and Teller/Weaver of Fairy Tails, with Verre Magic and Fairy Tail Ball as searchers
  • Turn 1 (going first): Open Magistus or Fairy Tail starters (Luna, Matchgiru, Rilliona, Spenta, Crowley) and extend into a Link or Fusion, keeping Ash Blossom and Droll-style hand traps for the opponent's first response
  • Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Infinite Impermanence, Droll) and Solemn-style interaction to stall the opponent's board, then extend through Magistus engines into a boss monster
  • Recovery: Recover from Magistus Spellcasters in the GY and banish via Verre Magic, Rilliona and Zoroa equip effects; Fairy Tail Ball and Tails of the Fairy Tails rebuild the Fairy Tail search line
  • After siding: Not available: the deck runs zero side-deck cards, so there is no post-side plan in the evidence

Why it scores here

The deck is scored as a system, not as an average of its card scores, and it is illegal as built: three copies of Ash Blossom and Super Polymerization, two Droll & Lock Bird, four forbidden or banned cards, and a 16-card Extra Deck. Its Magistus core is reliably present (about 94% chance of at least one archetype card in a 5-card opener, and about 79% chance of a searcher), which supports a decent T1 opening on paper. Interaction is broad (about 22 negation texts, 19 removal texts and 15 hand traps), so it can disrupt the opponent, but much of it is situational tech that adds bricks and dead draws. Median output and combo ceiling cannot be measured because there are no recorded boards, so those scores are text-based inference. Popularity and archetype usage did not earn points: the usage stats only show the archetype is real, and the side deck is empty, so adaptability scores low. The score is capped at 35 because the list is illegal and the evaluation is structural only.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 66 P(≥1 archetype core card in 5-card hand) ≈ 0.94; P(≥1 searcher in 5) ≈ 0.79; Magistus and Fairy Tail bootstrap lines (Inferred)
D2 Opening-Hand Quality & Brick Management 52 54 main slots with 26 tech and 15 hand-trap texts; ~6% estimated full-brick proxy; Super Polymerization and Droll overcount inflates redundancy (Inferred)
D3 Combo Conversion & Ceiling 55 No recorded combo boards; ceiling read from text of Magistus Fusion/Link/Xyz boss monsters and Fairy Tail chains (Inferred)
D4 Combo Floor & Median Output 45 No recorded boards, so median and floor cannot be measured; score reflects starter diversity from text only (Inferred)
D5 Interruption Resilience & Route Redundancy 58 Two engines (Magistus and Fairy Tail) plus 15 hand traps and recursion from GY give some redundant routes; no disruption data (Inferred)
D6 Resource Economy, Recovery & Grind 55 14 searcher texts and Fairy Tail Ball/Verre Magic recursion; no resource telemetry (Inferred)
D7 End-Board & Interaction Quality 66 22 negation, 19 removal and 15 hand-trap texts give broad interaction, but several are situational tech; Forbidden tech is not legal to run (Inferred)
D8 Going-Second & Board-Breaking Power 60 Going-second hand-trap coverage ≈ 0.87 in a 6-card hand, plus Droll, Harpie's Feather Duster and Solemn effects against the board (Inferred)
D9 Offensive Pressure & Closing Power 58 End-board ATK up to 2900 (Cosmo Queen, Zoroa Verethragna) and Mechaba 2500; closing depends on Extra Deck access (Verified stats, Inferred closing)
D10 Main Deck Efficiency & Flexibility 45 54 main with 30 distinct cards and 27 level-0 non-monsters; dense tech and off-archetype staples (exact-name purity 21%) reduce compactness (Verified composition)
D11 Extra Deck Efficiency & Coverage 50 16 Extra cards exceed the 15-card limit; mix of fusion, link and Xyz covers multiple lines but includes flex slots and two Fusion-only generic cards (Verified composition)
D12 Side Deck Adaptability 15 Side deck is empty (side 0), so there is no post-side adaptation at all (Verified legality)
D13 Matchup Coverage & Format Fit 40 No tournament link or dated meta sample; archetype meta-share unavailable (Provisional)
D14 Pilotability & Error Tolerance 40 Multiple engines, Fairy Tail and Magistus summon chains and several branching decision points; no combo examples to measure step count (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 53, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-8). Final formula: Illegal deck: 0.80*Structural(53) + 0.20*TournamentReliability(50) + ContextModifiers(-8) ≈ 44, then capped at 35 as a structural-only, illegal evaluation (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Core archetype cards are reliably present in the opening hand
  • Broad interaction package: 15 hand traps plus negation and removal texts
  • Multiple engines (Magistus and Fairy Tail) give some redundant routes

Weaknesses

  • Illegal as built: copy limits, forbidden cards and a 16-card Extra Deck
  • Zero side deck, so no post-side adaptation
  • High tech density lowers compactness and raises brick risk

Critical choke points

  • Single-copy Fusion and Link enablers in the Extra Deck
  • Dependence on Super Polymerization and Instant Fusion for Fusion access, which are legal-limited
Priority Remove Add Reason
1 Called by the Grave, Triple Tactics Talent, Secret Village of the Spellcasters, Charmer Quartet in Bloom Legal-limit replacements (for example, a second legal Magistus or Fairy Tail Spell/Trap) These four cards are Forbidden in TCG and make the list illegal; removing them is required before any normal evaluation
2 One Ash Blossom, one Super Polymerization, one Droll & Lock Bird Legal-copy-compliant Extra Deck and Main Deck counts Copy limits are exceeded (Ash 3 vs 2, Super Polymerization 3 vs 2, Droll 2 vs 1)
3 One Extra Deck card (flex fusion or link slot) A side deck of up to 15 cards The Extra Deck is 16 against a 15-card limit, and the empty side deck leaves D12 with no adaptation

Evidence & confidence

  • Verified: Legality status Illegal with 7 violations and 16 Extra Deck cards; Restricted banlist status for 13 cards; Archetype core inclusion and usage stats for 25 cards; Exact-name purity 21.4% and composition counts
  • Inferred: Hypergeometric starter and brick estimates; Going-first and going-second reads from hand-trap and tech density; Interaction density from card-text hints
  • Provisional: Meta Power (no dated metagame sample); Matchup fit and D13 (no tournament link)
  • Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or unknown Meta Power is provisional without a dated metagame sample Deck has no title and no side deck
