Magistus Deck #751764 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Magistus Fusion, Link and Xyz boards built from Spellcaster bodies, closed by Zoroa the Magistus Verethragna, Thunder King or Nibiru; Fairy Tail Prince of Fairies and Mulcharmy draw-and-board pressure
• Turn 1 (going first): Normal Summon a Spellcaster (Crowley, Rilliona, Genia, Fairy Tail Snow), search a Magistus card, then Fusion or Link with the Extra Deck options
• Turn 2 (going second): Ash Blossom and Droll & Lock Bird hand traps on the opponent's first Search or Summon, then a Super Polymerization or Spenta follow-up
• Recovery: Mulcharmy Fuwalos and Purulia draw cards when the field is empty, Pot of Sloth refills the hand, and Fairy Tail Luna and Matchgiru return from the GY
• After siding: Not available: the deck has no Side Deck, so no post-side plan exists in a best-of-3 format

Why it scores here

This list is Illegal as submitted: it runs 3 copies of Ash Blossom and Super Polymerization against a limit of 2, 2 Droll & Lock Bird against a limit of 1, and 5 Forbidden cards including Called by the Grave, Triple Tactics Talent, Anti-Spell Fragrance and Charmer Quartet. Under the guardrails the score is therefore capped and labelled structural-only. Structurally the deck reliably opens a Spellcaster starter with about 99% archetype-core access and roughly 86% searcher access in a 5-card hand (Inferred), so it can start an engine, but the engine is split across Magistus, Fairy Tail, Mulcharmy and Endymion pieces, which weakens coherence. Interaction is layered (Ash, Droll, Lightning Storm, Harpie's Feather Duster, Forbidden Droplet), yet the floor is limited by 31 distinct main-deck cards with only 21% exact-name Magistus purity and no Side Deck. No combo boards exist, so the ceiling and median are text-only inference, and popularity and archetype usage were not counted as power. The score was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 47, Going First ≈ 45, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: illegal_cap (-4); banlist_exposure (-6). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 45.2, then Illegal cap applied as modifier to 35

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 hand-trap and negation density (7 hand traps, 13 negation-text cards)
• High archetype-core access (about 99% open at least one core card in a 5-card hand, Inferred)
• Recursion and draw engines (Mulcharmy, Pot of Sloth, Fairy Tail GY effects)
• Strong closing bosses at 2900 to 3300 ATK

Weaknesses

• Illegal copy counts and five Forbidden cards in the main deck
• No Side Deck in a best-of-3 format
• Low archetype purity (21.4%) splits the engine across Magistus, Fairy Tail, Mulcharmy and Endymion
• High decision load and conditional card text

Critical choke points

• Only the Magistus Link and Fusion chain provides a board; losing the Spellcaster starter stalls it
• Ash Blossom and Droll are single-copy-limit cards in the legal build, so the hand-trap count drops after fixing the list

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 counts within the TCG size rules; Copy-limit violations and banlist statuses from legality; Archetype purity 21.4% and archetype spread from composition
• Inferred: Opening-hand access probabilities (hypergeometric, Main Deck only); Strategy classification from card text; Interaction and recovery reads from card text
• Provisional: Meta Power (null); Matchup and format fit (no tournament link)
• Data gaps: Illegal list: scoring is structural-only and capped No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second, matchups or bricks Meta Power is provisional without a dated metagame sample Composition field off_archetype_copies reports 55, which conflicts with archetype_spread (23 generic plus archetype-tagged cards); treated as a data quirk
