Identity & game plan

  • Win condition: Extra Deck boss monsters (Galaxy-Eyes Antimatter Dragon, Zoroa the Magistus Verethragna, Witchcrafter Vice-Madame, Tornado Dragon, Witchcrafter Haine) reached through Spellcaster-based Xyz and Fusion lines; Fairy Tail direct-attack and Mulcharmy draw pressure
  • Turn 1 (going first): Open on a searcher (20 copies, P(at least one in hand of 5) about 0.90), add an Endymion or Witchcrafter engine piece, then Xyz or Fusion into a boss while holding MST, Cosmic Cyclone or Typhoon for the opponent's answer
  • Turn 2 (going second): Use the 2 hand traps (Artifact Lancea) and the removal spells to stop the opponent's board, then rebuild through Mulcharmy draw and Endymion searches; the 6-card hand has a lower hand-trap hit rate (about 0.20)
  • Recovery: Recycle Witchcrafter Creation and Fairy Tail Ball from the GY, use Witchcrafter GY effects and Verre Magic to rebuild the Spellcaster count, and re-search Endymion cards with Spell Power Mastery
  • After siding: No side deck is registered, so there is no post-side plan in the export

Why it scores here

The deck opens reliably because 20 searcher-text cards give a roughly 0.90 chance of at least one searcher in a 5-card opening hand, so its starters are accessible; that consistency is an Inferred hypergeometric estimate, not a measured rate. It converts plans through a broad set of Spellcaster Xyz and Fusion bosses (Galaxy-Eyes, Zoroa, Vice-Madame, Haine), and its 24 removal-text and 6 negation-text cards give it real end-board interaction. Only 16.7% of the main deck is exact-name Magistus and 60 of 72 main copies sit outside that name, so the list works as a Toolbox of several sub-archetypes rather than one coherent engine, which caps its engine-cohesion and efficiency scores. There is no side deck and no recorded combo boards, so the going-second plan, post-side adaptability and median output are scored from text and structure only and carry wide uncertainty. Popularity was not a factor: the archetype core covers only 4 of its 10 most-used cards, and no points come from averaging individual card scores.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(at least one searcher in hand of 5) about 0.90 across 20 copies; core Archetype group 8 copies at 0.54 (Inferred)
D2 Opening-Hand Quality & Brick Management 55 Many conditional cards (Egyptian God Sphere Mode x3, Mulcharmy requires an empty field, Fairy Tail Ball needs a Fairy Tail target), giving moderate brick risk (Inferred)
D3 Combo Conversion & Ceiling 60 Engine text supports Endymion, Witchcrafter and Magistus lines, but no recorded boards exist, so the ceiling is text-only (Inferred)
D4 Combo Floor & Median Output 45 No combos_evidence rows and no median power index; floor set from starter diversity and 2-card bootstrap assumptions (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Three independent removal spells (MST, Cosmic Cyclone, Typhoon) and several GY recursion effects give route redundancy (Inferred)
D6 Resource Economy, Recovery & Grind 60 Recovery is text-supported by Witchcrafter Creation, Fairy Tail Ball and Spell Power Mastery; LP costs on Cosmic Cyclone and Regulus reduce economy (Inferred)
D7 End-Board & Interaction Quality 66 24 removal-text and 6 negation-text cards plus 2 hand traps give broad interaction; 3 copies each of MST, Cosmic Cyclone and Typhoon (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 45 Only 2 hand traps and no recorded going-second boards; Mulcharmy draw partly compensates (Inferred)
D9 Offensive Pressure & Closing Power 65 Boss ATK up to 4000 (Galaxy-Eyes) plus 2700 to 2900 fusion and Xyz bosses; direct-attack text on Fairy Tail monsters (Verified stats, Inferred closing)
D10 Main Deck Efficiency & Flexibility 48 57 main cards with 30 distinct names; 15 singletons and 60 of 72 off-name copies reduce coherence (Verified composition)
D11 Extra Deck Efficiency & Coverage 50 All 15 Extra slots are used: 6 Fusion, 9 Xyz, no Link; several slots (Galaxy-Eyes needing Level 9 Xyz, Eclipse Twins, Dark Ceruvim Irisfil) lack clear support in the list (Verified composition, Inferred fit)
D12 Side Deck Adaptability 15 No side deck is registered in the export (side_count 0), so post-side adaptability cannot be credited (Verified)
D13 Matchup Coverage & Format Fit 50 No tournament link and no dated metagame sample; archetype share is unavailable, so this is Provisional
D14 Pilotability & Error Tolerance 45 Multi-archetype sequencing, Xyz and Fusion mixes and many optional effects create a high decision load (Inferred)

How the score was computed

Strategy profile: primary Toolbox 100% (secondary Midrange used as a tiebreak only). Structural ≈ 53.6, Going First ≈ 58, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: No side deck (-3); Engine conflicts and low exact-name purity (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ — · 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

  • Dense searcher count (20) gives high opening-hand accessibility
  • Broad removal and negation text across three triple-copy spells plus Fairy Tail and Witchcrafter effects
  • Multiple high-ATK Extra Deck bosses across Xyz and Fusion

Weaknesses

  • Low exact-name purity (16.7%) and 60 off-archetype copies make the engine less coherent
  • No side deck registered
  • Extra Deck slots include cards with weak support in this list

Critical choke points

  • Single hand trap count (2) limits going-second interaction
  • Spellcaster count drives both Fusion and Xyz summons; losing Spellcasters to removal or negation stalls several lines
Priority Remove Add Reason
1 One copy of Egyptian God Sphere Mode A Magistus or Endymion searcher or engine piece Reduces off-archetype dead draws and improves engine coherence (Inferred)
2 A generic Xyz with no archetype link (Dark Ceruvim Irisfil) Droll & Lock Bird or a further Magistus Extra Deck boss Core cards in usage stats are missing and this slot is weakly supported (Inferred)
3 None A 3 to 5 card side deck with hand traps and anti-meta cards Side deck adaptability scores 15 with no side deck registered (Verified)

Evidence & confidence

  • Verified: Main 57 and Extra 15 are within OCG size rules; no violations; Fairy Tail - Snow is Limited with 1 copy run, which is legal; Core cards present: 4 of 10 (usage stats); Composition and archetype spread from the export
  • Inferred: Opening-hand probabilities (hypergeometric, Main Deck only); Dimension scores from card text and structure; Hand-trap and going-second estimates
  • Provisional: Meta power is null; no dated metagame sample; Matchup fit (D13) scored without meta share
  • 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 and going-second splits are Inferred Meta power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
