Mitsurugi Deck #770099 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Ritual Summon Reptile boss monsters (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi) via Mitsurugi Ritual and Mitsurugi Mirror, then press with ATK and board-wipe or negate effects; Link and Synchro pressure from the Extra Deck (Psychic End Punisher, Enigmaster Packbit, Stardust Dragon) once the Ritual board is established
• Turn 1 (going first): Open Reptile searchers (Mitsurugi no Mikoto, Saji / Kusanagi / Aramasa, Mitsurugi no Miko, Wousu) and Mitsurugi Ritual to reach a Level 8 Ritual boss; protect with Ash Blossom and Droll
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, D.D. Crow, Nibiru) to break the opponent's first engine, then Ritual Summon through the cleared board
• Recovery: Reptile monsters recycle through the GY and banish-based effects; Mitsurugi Mirror and Mitsurugi Prayers rebuild the Ritual line from the GY (Inferred from card text)
• After siding: No Side Deck is registered, so no post-side plan exists in this export

Why it scores here

The deck reliably opens its Mitsurugi engine: the 15-card archetype core gives about an 81% chance of at least one core card in a 5-card opening hand (Inferred, hypergeometric). Its Ritual lines convert into Level 8 bosses and removal or negation text (Ash Blossom, Great Purification, Ghost Ogre, Lightning Storm), which lifts interaction and pressure. The score is dragged down by the deck's structure: 24% exact-archetype purity, 3-copy staples and generic cards that dilute the engine, and no parseable combo boards, so the floor and median are unmeasured. The deck is Illegal in OCG (7 violations including 4 Forbidden cards and copy-limit overruns), so the score is capped and reflects only a theoretical, structural read. Popularity in the usage stats confirms the list is real and accessible but earned no points on its own, and the cards were not averaged into the score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12). Final formula: Illegal cap: the blended value (0.80*51 + 0.20*45 = 49.8, less 12 for banlist exposure = about 38) is not used; the Illegal deck is capped to 20 and labelled theoretical/structural-only. Meta Power is null (Provisional).

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

• Archetype core is highly accessible (about 81% per opening 5)
• Ritual bosses (Ame no Murakumo 3200 ATK, Futsu no Mitama 2000/3400) and removal/negation text give real interaction
• Large hand-trap count (14) gives strong going-second disruption

Weaknesses

• Illegal in OCG: copy-limit overruns and 4 Forbidden cards
• Low archetype purity (24.3%) with many generic 3-copy cards
• No Side Deck; no post-side plan
• No combo or tournament evidence; floor and median unmeasured

Critical choke points

• Mitsurugi Ritual and the Reptile tribute chain: a missing Reptile or Ritual Spell stops the Level 8 boss
• Ash Blossom and Droll copy limits: legal copies must be reduced before the list can be played

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal in OCG: 7 violations (4 Forbidden, 3 copy-limit overruns); Main 55, Extra 15, Side 0; main size within 40-60 and extra within 0-15; Archetype purity 24.3% (17 of 70 copies exact-name Mitsurugi)
• Observed: Usage stats: Mitsurugi core cards appear in 70-87% of the archetype's decks
• Inferred: About 81% chance of at least one archetype core card in a 5-card opening hand; About 84% chance of a hand trap going second; Ritual engine and recursion plan read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament or meta data); Post-side plan (no Side Deck)
• Data gaps: no combos supplied: floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry (going-first/second, matchup, brick, starter rates) no Side Deck registered Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
