Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Extra Deck boss monsters (Zoroa, the Magistus Verethragna; Link and Fusion bosses) reached through Magistus, Endymion and Fairy Tail summon chains (Inferred from card text, no recorded boards); Fairy Tail Fusion/XYZ pressure and Fusion Summon of Mixousia or Garura through Super Polymerization and Metamorphosis (Inferred)
- Turn 1 (going first): Normal Summon a level 4 Spellcaster or Mulcharmy draw engine, then search a second Magistus or Endymion starter with Verre Magic, Spenta or Crowley and link or fuse into a boss (Inferred; the three sub-archetypes compete for the same slots)
- Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Droll & Lock Bird and Evenly Matched to answer the opponent's first combo, then rebuild through Mulcharmy draws and Fairy Tail Ball (Inferred)
- Recovery: Mulcharmy draw effects and Fairy Tail Ball/Once Upon a Fairy Tail to refill from Deck, GY and banishment after an interruption (Inferred)
- After siding: No Side Deck is registered, so there is no post-side plan (Verified: side_count 0)
Why it scores here
The list is illegal as built: Ash Blossom & Joyous Spring and Super Polymerization are each run three times against an OCG limit of two, so it receives only a structural read, not a normal final score. Its engine is split across three sub-archetypes (Magistus, Endymion and Fairy Tail, plus Mulcharmy draw cards), and only 12 of 55 main-deck copies carry the exact Magistus name, so consistency is capped by competing starters rather than by any single brick. Interaction is the strongest part of the system: 11 hand traps and 15 negation-text cards give layered answers on both turns, which supports its going-second and interruption scores. Ceiling and median output could not be measured because the deck has no recorded boards, and the 0-side list leaves no post-side adaptation. The score was not produced by averaging card scores or by the archetype's usage stats, which confirm the list is real but do not make it strong.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 50 | P(>=1 of a 3-copy starter in 5-card hand) ~0.25; archetype core group P(>=1 core in hand) ~0.95, but the exact Magistus name is 12 copies across three sub-archetypes (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | Mulcharmy draw effects need an empty field, Fairy Tail and Endymion engines conflict on Extra Deck slots, and 15 singletons add dead draws (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | Text-only read of Magistus fusion and link bosses with Fairy Tail XYZ/Fusion; no recorded boards exist so the ceiling is unmeasured (Inferred) |
| D4 | Combo Floor & Median Output | 40 | median_power_index unavailable and no recorded boards; floor is unmeasured and cannot be scored above a low prior (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Ash Blossom, Effect Veiler, Ghost Belle and Droll & Lock Bird give several independent answers, but the engine has few routes after a clean hit (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | 21 searcher-text cards and Mulcharmy draw effects give card economy; Fairy Tail Ball and Once Upon a Fairy Tail recover from GY and banishment (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | 15 negation-text and 11 hand-trap cards across Ash Blossom, Veiler, Ghost Belle, Dark Ruler No More and Harpie's Feather Duster give broad interaction (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 55 | Hand traps and Dark Ruler No More handle opposing boards on the second turn, but no board-breaker or going-second split is recorded (Inferred) |
| D9 | Offensive Pressure & Closing Power | 45 | Zoroa Verethragna at 2900 ATK and Summon Sorceress at 2400 ATK provide closing bodies, with no recorded end-board data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 55 main cards across 31 distinct names; 58 of 55 copies are off the exact archetype name and 17 tech cards dilute the engine (Verified count, Inferred effect) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra Deck slots hold 7 Fusion, 6 Link and 2 XYZ monsters, a full ladder with several Magistus-gated bosses (Verified composition, Inferred use) |
| D12 | Side Deck Adaptability | 10 | No Side Deck is registered, so post-side adaptability is effectively zero (Verified: side_count 0) |
| D13 | Matchup Coverage & Format Fit | 45 | Archetype meta-share and tournament data are absent; format fit is Provisional and needs a dated meta sample (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Three engines, several Quick Effect hand traps and multi-step Extra Deck chains raise the number of decision points (Inferred) |
How the score was computed
Strategy profile: Combo primary with Toolbox secondary; disclosed, no re-weighting to force a score. Structural ≈ 48, Going First ≈ 45, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (-4); Engine conflict (-4). Final formula: Illegal list: structural-only, capped low. 0.80*Structural(48) + 0.20*TournamentReliability(35) + ContextModifiers(-8) = 37; Meta Power provisional/null
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
- Layered interaction: 11 hand traps and 15 negation-text cards cover both turns
- Extra Deck coverage across Fusion, Link and XYZ with several boss options
- Recovery through Mulcharmy draw effects and Fairy Tail Ball
Weaknesses
- Illegal as built: two cards exceed the OCG copy limit
- Three sub-archetype engines dilute starter consistency (exact-name purity 17.1%)
- No Side Deck, so no post-side adaptation
- No recorded boards, so the combo ceiling and median are unmeasured
Critical choke points
- Single-copy Extra Deck bosses that depend on Magistus or Endymion material
- Starter density across three archetypes means a clean hand trap can leave the chain without a live engine
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1 copy of Ash Blossom & Joyous Spring | 1 copy of an OCG-legal card of the same role | Brings the Ash Blossom copy count to the OCG limit of 2 |
| 2 | 1 copy of Super Polymerization | 1 Magistus or Endymion starter from the Main Deck | Brings Super Polymerization to the limit of 2 and consolidates the engine toward one archetype |
| 3 | 1 to 2 off-archetype tech cards | Side Deck slots (up to 15 for OCG) for matchup flexibility | Adds the missing post-side plan (Inferred) |
Evidence & confidence
- Verified: Legality: Illegal (Ash Blossom and Super Polymerization each 3 copies vs OCG limit 2); Deck size: 55 Main, 15 Extra, 0 Side, within size rules; Extra Deck: 7 Fusion, 6 Link, 2 XYZ; Exact-name Magistus purity 17.1%; hand_trap 11; negation_text 15; Archetype core group P(>=1 in 5) = 0.95; per-card hypergeometric draw odds
- Inferred: Engine consistency and brick rate from card text and hypergeometric draws; Interaction quality from negation and hand-trap text; Going-first and going-second plans from card text; Closing power from Extra Deck ATK values
- Provisional: Meta and format fit (no dated sample; tournament_context unavailable)
- Data gaps: no combos supplied (combo floor, median and ceiling are text-only inference) no tournament link (archetype meta-share and match record absent) no win-rate telemetry (going-first/second, matchup, brick and starter rates) no Side Deck (post-side plan cannot be evaluated) Meta Power provisional without a dated metagame sample
