Mitsurugi Deck #771491 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Ritual Summon
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ritual Summon Reptile Ritual Monsters (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi) via Mitsurugi Ritual / Mitsurugi Mirror, then press a 3000+ ATK board or Ruler of the End of the World; Fusion, Link and Xyz boss monsters from the Extra Deck (Extox Hydra, Starving Venom, Ragnaraika Stag Sovereign, Number 90) as off-archetype payoffs
• Turn 1 (going first): Opening Mitsurugi searchers (Saji, Kusanagi, Aramasa, Wousu) into Ritual setup with Mitsurugi Ritual; hand traps (Ash, Ghost Ogre, Effect Veiler) held up for the first opposing summon
• Turn 2 (going second): Hand traps Ash Blossom, Ghost Ogre and Effect Veiler plus Droll & Lock Bird answer the opponent's first engine; Mitsurugi Great Purification and Mitsurugi Tempest serve as backrow interaction
• Recovery: Ritual monsters and Mitsurugi searchers recur from the GY through Pre-Preparation/Ragged Records and Mitsurugi Prayers, but these are the copies over the limit
• After siding: Not evaluable: the deck runs no side deck (side_count 0), so no post-side plan exists in the evidence

Why it scores here

The deck is Illegal: four cards exceed their OCG copy limits (Pre-Preparation of Rites, Ash Blossom & Joyous Spring, Super Polymerization and Mitsurugi Prayers), so the score is capped low and is structural-only. Structurally it is a Midrange Mitsurugi list: the Ritual core (21 exact-name Mitsurugi copies, about 81% chance of at least one core card in a 5-card opening hand) gives it a plausible opening, and 13 hand traps plus about 14 negation texts give it real interaction density. Its weaknesses are the lack of a combo dataset, 49 off-archetype copies (30% exact-name purity), and 22 tech cards that dilute the engine. The score comes from consistency, interaction and closing power on the system, not from Mitsurugi being a popular archetype, and not from averaging the card scores; there is no side deck, so post-side adaptability is scored very low, and no meta data exists to score matchups.

Dimension scores

How the score was computed

Strategy profile: 0.85 Midrange / 0.15 Toolbox (disclosed; not a balanced default). Structural ≈ 48, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflicts (-2). Final formula: Uncapped: 0.80*Structural(48) + 0.20*TournamentReliability(40) + Modifiers(-10) = 36; Illegal cap applied, so final = 30 (Meta 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

• Core Mitsurugi searchers and Ritual route are consistent at the archetype level
• Dense hand-trap and negation coverage (13 hand traps, 14 negation texts)
• High-ATK Ritual and Link payoffs give closing power

Weaknesses

• Illegal copy counts on four cards
• Low exact-name archetype purity (30%)
• Empty side deck
• No recorded combos or tournament data to validate the ceiling or median

Critical choke points

• Mitsurugi Ritual / Mitsurugi Mirror as the single Ritual enabler
• Ash Blossom and the other hand traps as the only early disruption

Recommended changes

Evidence & confidence

• Verified: Four copy-limit violations (OCG ban list); Main 55 / Extra 15 / Side 0 within size rules; Archetype purity 21 of 70 total exact-name copies; Card stats and text excerpts
• Inferred: Hypergeometric opening-hand odds; Hand-trap and negation density as interaction quality; Ritual-route consistency and brick estimate
• Provisional: Matchup and format fit (no dated meta); Tournament reliability
• 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 starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
