Magistus Deck #773487 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Tempo
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Magistus and Fairy Tail Extra Deck boss summons (Magistus Chorozo, Zoroa the Magistus Verethragna, Aiwass) backed by Endymion and Fairy Tail link and fusion lines; Fairy Tail Fusion and Xyz pressure (Teller of Fairy Tails, Weaver of Fairy Tails, Fairy Tail - Wiccat)
• Turn 1 (going first): Normal Summon a Tuner or Spellcaster starter, use Verre Magic or Fairy Tail Ball to search, then open Fusion or Link material through Super Polymerization or Crowley (theoretical; no board data)
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre, Nibiru and Droll & Lock Bird for the opponent's first summon or search, then rebuild through the Fairy Tail or Endymion recursion lines (theoretical; no board data)
• Recovery: Recycle Magistus and Witchcrafter cards through Witchcrafter Creation, Spenta and Genni banish effects, and Fairy Tail Ball recursion
• After siding: Not evaluable: the deck has no Side Deck (side_count 0), so no post-side plan exists

Why it scores here

The deck is Illegal: two cards exceed their Semi-Limited copy limit, so it receives a capped, theoretical-only score. Its structural read is 53, from the Combo profile applied to the 14 dimensions. The main deck spans at least five sub-archetypes (Magistus 13 copies, Fairy Tail 8, Endymion 7, Mulcharmy 6, Forbidden 4) and 28 generic cards, so only 18.6% of copies are exact-name Magistus. That low purity lowers the engine-coherence and brick scores even though the core Magistus group is well represented (P(at least one open in a 5-card hand) = 0.959). Interaction is dense: 13 hand traps, 15 negation-text cards and 12 removal-text cards give the deck real resilience and a strong going-second plan. No recorded boards exist, so the combo ceiling and median are text-only inferences and are not averaged from card scores. Popularity was not credited: the archetype usage stats confirm the deck is real, not that it is strong. The score is capped at 28 because the list breaks the copy limit and has no Side Deck.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-4); engine_conflicts (-4); no_side_deck (-3). Final formula: 0.80*Structural(53) + 0.20*TournamentReliability(40) + modifiers(-11) = 39.6, capped to 28 because legality is Illegal; the result is theoretical/structural-only (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and negation coverage (13 hand traps, 15 negation-text cards) for going second
• Multiple recursion and search routes (Witchcrafter Creation, Fairy Tail Ball, Spenta, Genni) for recovery
• Broad Extra Deck coverage across Fusion, Link, Xyz and Synchro (15 cards) with high-level bosses

Weaknesses

• Illegal list: Ash Blossom and Super Polymerization exceed their Semi-Limited copy limit (3 copies, 2 allowed)
• Five sub-archetypes with 18.6% exact-name purity dilute the engine and raise brick risk
• No Side Deck, so no post-side plan for best-of-3
• No recorded boards, so combo conversion and median output are unknown

Critical choke points

• Summoning the Magistus or Endymion Link and Fusion bosses depends on a few starters (Crowley, Verre, Genia, Regulus) and on Super Polymerization, which is over the copy limit
• Instant Fusion, Droll & Lock Bird, Summon Sorceress and Fairy Tail - Snow are each Limited at one copy, so losing any one removes a key piece

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within the TCG size rules (40-60, 0-15, 0-15); Ash Blossom & Joyous Spring and Super Polymerization each run 3 copies against a Semi-Limited limit of 2 (Illegal); Archetype purity: 13 exact Magistus copies of 55 main-deck cards (18.6%); Limited cards (Droll & Lock Bird, Fairy Tail - Snow, Instant Fusion, Summon Sorceress) are each at one legal copy
• Observed: usage_statistics: Endymion Crescent Magistus, Ash Blossom and Crowley are 100% inclusion; 14 of 25 archetype core cards are present (56%)
• Inferred: Core-group hit probability 0.959 in a 5-card opener; brick estimate 0.041 (hypergeometric proxy); Going-second hand-trap coverage 0.819 in a 6-card hand; Engine coherence and combo ceiling are judged from card text only
• Provisional: Meta Power is null: no dated metagame sample is supplied; D13 matchup fit has no tournament or matchup data
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup, brick and OTK rates are Inferred or Unknown no side deck supplied — post-side plan cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
