Mitsurugi Deck #770174 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 58 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Ritual Summon a Mitsurugi Reptile (Ame no Murakumo no Mitsurugi or Futsu no Mitama no Mitsurugi) via Mitsurugi Ritual / Mitsurugi Mirror, then press with the large Ritual body (Inferred); Clown Crew Extra Deck summons (Clown Crew Biancaviso, Clown Crew Meteor, Clown Crew Diabolo) for pressure and piercing (Inferred)
• Turn 1 (going first): Open a Mitsurugi searcher or Ritual starter, use Mitsurugi Prayers or a Reptile searcher to set up Mitsurugi Ritual, and protect the turn with Ash Blossom / Droll / Ghost Belle (Inferred)
• Turn 2 (going second): Use the hand-trap suite (Ash Blossom, Ghost Belle, Droll, Evenly Matched, Nibiru) to answer the opponent's first summon, then convert the surviving hand into a Ritual Summon (Inferred)
• Recovery: Recover Reptile and Mitsurugi monsters from the GY through Mitsurugi Ritual / Mitsurugi Mirror and the Mitsurugi no Mikoto searchers (Inferred)
• After siding: No side deck is registered; there is no post-side plan in the evidence (Verified gap)

Why it scores here

This list is Illegal under the OCG banlist: it runs three Forbidden copies (Ame no Habakiri no Mitsurugi, Called by the Grave, Number 60) and four cards over their Limited or Semi-Limited copy caps (Mitsurugi Prayers at 3 of 1, Droll & Lock Bird at 2 of 1, Ash Blossom and Super Polymerization at 3 of 2). The rubric therefore caps the score and marks it theoretical/structural only. The structural read is that the Mitsurugi ritual engine and the 16-copy archetype core give a reasonably accessible T1 starter (about 81% for at least one core card in a 5-card hand, Inferred), and the 12 hand traps give strong interaction on the opponent's turn. Against that, the deck is only 26% exact-archetype by name, has 23 spell/trap slots with weak non-engine density, has no side deck, and has no recorded boards, so the floor and median are unknown. Popularity and archetype usage were not counted as power, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_plan (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 50.6, then capped to 30 because the deck is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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

• Ritual engine with a 16-copy archetype core and an 81% chance of at least one core card in hand (Inferred)
• Layered interaction: 12 hand traps plus Lightning Storm, Evenly Matched, and Mitsurugi Great Purification (Inferred)
• High closing ceiling through Ame no Murakumo and Clown Crew Biancaviso (Inferred)

Weaknesses

• Illegal under the OCG banlist: three Forbidden cards and four copy-limit breaches (Verified)
• Low exact-archetype purity (26%) and many off-archetype staples (Verified)
• No side deck and no post-side plan (Verified)
• No recorded boards, so the combo floor and median are unknown (Verified gap)

Critical choke points

• Mitsurugi Ritual or Mitsurugi Mirror access; without them the Ritual monsters are dead cards (Inferred)
• Ash Blossom and Droll are over-limit, so the hand-trap protection shrinks once the deck is made legal (Verified)

Recommended changes

Evidence & confidence

• Verified: Forbidden, Limited, and Semi-Limited copy violations (legality block); Main 58 / Extra 15 / Side 0 counts within size rules; Archetype purity 26% and the zero side deck
• Inferred: Archetype core P(at least one) of about 0.81 (hypergeometric); Interaction density and closing power from card text; Going-second hand-trap coverage of about 0.77
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry: going-first and going-second splits are Inferred No side deck registered: post-side plan cannot be evaluated Meta Power is Provisional unless a dated metagame sample is supplied
