Mitsurugi Deck #773339 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 54 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ritual Summon Reptile boss monsters (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi) and Extra Deck Link/Xyz/Fusion threats after recovering Mitsurugi Reptiles from the Deck; Extra Deck follow-up through Super Starslayer TY-PHON, Ruler of the End of the World and Galaxy-Eyes Photon Lord, with Mulcharmy draw pressure
• Turn 1 (going first): Turn 1 Reptile search (Mitsurugi no Mikoto Aramasa or Saji, Mitsurugi Magatama or Mitsurugi Ritual) into a Ritual Summon of a Mitsurugi boss, backed by hand traps
• Turn 2 (going second): Hand trap (Ash Blossom, Ghost Belle, Ghost Ogre) or Solemn negation to answer the opponent's first board, then Ritual or Fusion follow-up on the next turn
• Recovery: Reptile recursion from GY via Futsu no Mitama no Mitsurugi and Mitsurugi Great Purification, plus Mulcharmy draws to refill the hand
• After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists in this list

Why it scores here

This list is Illegal in OCG: four cards exceed their copy limits (Pre-Preparation of Rites, Mitsurugi Prayers, Ash Blossom and Super Polymerization), so the score is capped and reported as theoretical and structural only. Structurally the system is reasonably engine-accessible: P(at least one searcher in a 5-card opening) is about 0.91 and the Reptile search cards give repeated starter access, so the consistency read is Inferred. Interaction is dense (about 12 negation and 18 removal-text cards across hand traps, Solemn cards, Lightning Storm and Harpie's Feather Duster), which carries the end-board and going-second dimensions. Combo ceiling and median are unscored because no recorded boards exist, and the 26% exact-archetype purity and 31 generic slots pull efficiency down. The score comes from consistency, interaction and resilience on the system, not from Mitsurugi's popularity (usage data confirms the list is real, not that it is strong) and not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: primary Midrange; Toolbox used for coverage weight only. Structural ≈ 59, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist_exposure (-8); illegal_cap (-4). Final formula: Illegal list: theoretical only. 0.80*Structural(59) + 0.20*TournamentReliability(52) + banlist modifier(-8) = 39, capped at 35 for Illegal status. Meta Power is null (Provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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

• Very high starter access: 20 searcher-text cards with P(at least one in opening 5) ≈ 0.91
• Dense interaction across hand traps, Solemn cards and sweepers
• Strong end-board ATK from Ritual and Link threats

Weaknesses

• Illegal in OCG: four cards over copy limit
• No Side Deck
• Low archetype purity (26%) and 31 generic slots dilute the engine
• No recorded combos to confirm floor or ceiling

Critical choke points

• Reptile search cards are the single engine entry; losing them to hand traps or sweepers slows the whole line
• Ritual Summon requires Tribute setup that many hands will not have

Recommended changes

Evidence & confidence

• Verified: Main 54 / Extra 15 / Side 0 are within OCG size rules; Four copy-limit violations (Pre-Preparation of Rites, Mitsurugi Prayers, Ash Blossom, Super Polymerization); Usage data shows the Mitsurugi core is real (usage_statistics available, 61.5% core present)
• Inferred: Starter consistency from hypergeometric estimate (P ≈ 0.91); Interaction quality from negation and removal card text; Going-first and going-second split from text, not boards
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no 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 match record absent no win-rate telemetry exists in YGOVN for going-first/second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied deck title is null; no Side Deck present
