Magistus Deck #774181 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• 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: Extra Deck boss monsters (Zoroa, the Magistus Verethragna, Magistus Chorozo, Invoked Oceanus, Teller/Weaver of Fairy Tails) summoned through Fusion, Link and Xyz lines after the Magistus/Endymion/Fairy Tail starters open the board (Inferred from card text and Extra Deck composition); Hand-trap-supported board protection followed by Link/Xyz pressure; no recorded line data to confirm which route converts most often
• Turn 1 (going first): Open a Magistus, Endymion or Fairy Tail starter with Crowley/Regulus/Fairy Tail monsters and searchers, then Link or Fusion into a boss while holding a hand trap for the opponent's first response (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Nibiru or Droll & Lock Bird to interrupt the opponent's first summon or activation, then rebuild through searchers and Extra Deck summons (Inferred)
• Recovery: Searchers (17 copies by text) and Mulcharmy/Fairy Tail recursion from hand and GY to refill starters after a hand trap or negation (Inferred)
• After siding: No side deck is registered, so no post-side plan can be evaluated; a best-of-3 deck with 0 side cards has no adaptation path (verified from composition)

Why it scores here

The list is Illegal: Ash Blossom & Joyous Spring and Super Polymerization are each run three times against a Semi-Limited limit of two, so the normal Final Contextual score is capped and this 30 is a structural, theoretical read only. Structurally the deck can open its archetype core reliably (P(at least one of the 28 core-group cards in a 5-card opening hand) ≈ 0.98, Inferred), and its 10 hand traps plus 15 negation-text cards give it a credible going-second interaction layer (P(at least one hand trap in a 6-card hand) ≈ 0.72, Inferred). Its conversion and median output cannot be measured: no combos were supplied, so the ceiling and floor scores rest on card text alone. Popularity and archetype usage stats (the core is 64% present) confirm that the list is a recognised build but earned no points on their own, and the score does not average the individual card scores. Exact-name archetype purity is only 12.9%, with the Endymion, Fairy Tail, Mulcharmy, Witchcrafter and Solemn sub-archetypes sharing the Extra Deck, which lowers pilotability and engine coherence, and the empty side deck leaves no post-side plan.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49.5, Going First ≈ 52, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-6); Engine conflicts (-4); No side deck (-2). Final formula: Illegal cap applied: 0.80*Structural(49.5) + 0.20*TournamentReliability(40) = 47.6; modifiers total -12 gives 35.6; capped to 30 for an Illegal list (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Opens a core archetype starter in most 5-card hands (≈0.98 for the core group, Inferred)
• Ten hand traps plus negation-text cards give a credible going-second interaction layer (Inferred)
• Searcher-heavy Main Deck (17 cards by text) supports recovery after an interruption (Inferred)

Weaknesses

• Illegal: Ash Blossom & Joyous Spring and Super Polymerization exceed the Semi-Limited limit of 2 (Verified)
• Low archetype purity (12.9%) and several competing sub-archetypes weaken engine coherence (Verified composition, Inferred scoring)
• No side deck (0 cards) for a best-of-3 format (Verified)
• No combo, guide or tournament evidence, so conversion and meta claims cannot be verified (Verified data gap)

Critical choke points

• Single Extra Deck boss lines depend on specific Fusion/Link/Xyz materials, so one missed starter can stall the board (Inferred)
• Ash Blossom and Solemn Judgment are the main interaction; with the copy-limit violations and Limited Solemn Judgment, the deck cannot run its intended interaction density legally (Verified legality, Inferred impact)

Recommended changes

Evidence & confidence

• Verified: Main deck 55 cards, Extra deck 15 cards, both within size rules; Ash Blossom & Joyous Spring: 3 copies vs Semi-Limited limit 2 (over limit); Super Polymerization: 3 copies vs Semi-Limited limit 2 (over limit); Restricted cards: Solemn Judgment, Instant Fusion, Summon Sorceress, Droll & Lock Bird, Fairy Tail - Snow (Limited, 1 copy each); Exact-name archetype purity 12.9%; side deck count 0
• Inferred: Core-group opening hand access ≈ 0.98 (hypergeometric proxy); Going-second hand-trap access ≈ 0.72 for at least one in 6 cards; Midrange primary strategy and Toolbox secondary, based on the archetype spread and tech count; Structural scores for D1–D14 from card text and composition
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (no tournament or meta data)
• 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 are absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Deck title is null Side deck is empty, so post-side behaviour cannot be scored Meta Power is provisional without a dated metagame sample
