Mitsurugi Deck #762847 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 34/100 (±8 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 10 violation(s).

Identity & game plan

• Win condition: Ritual Summon Reptile monsters (Ame no Murakumo, Futsu no Mitama) through Mitsurugi Ritual and Mitsurugi Prayers, then press with high-ATK boss monsters; Link and Fusion boss monsters (Perfectron Hydradrive Dragon, Artemis, Selene) once the Mitsurugi line has established board
• Turn 1 (going first): Normal Summon a Mitsurugi no Mikoto searcher, add a Mitsurugi Spell/Trap, then Ritual Summon through Mitsurugi Ritual or Mitsurugi Prayers. The forbidden Ame no Habakiri is the intended top end and is absent from any legal build.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Droll & Lock Bird for the opponent's first Special Summon or search, then rebuild with Mitsurugi searchers. Interaction is strong; the board-breaking top end is not.
• Recovery: Recur Reptile monsters via Mitsurugi Great Purification and Mitsurugi Mirror, and use Dark Magician and Magician's Rod searches to refill the hand
• After siding: Not evaluable. The deck runs zero side-deck cards, so there is no post-side plan.

Why it scores here

This list is Illegal in TCG: nine distinct cards are Forbidden and run at 1 to 3 copies, including the Mitsurugi engine's top end (Ame no Habakiri no Mitsurugi, 3 copies). The score therefore reflects only the structural shape of the 42+15 system, not a legal build. Starter access is reasonable: the archetype core is present in 93.8% of going-first opening hands, and 19 searcher-text cards refill the hand. Interaction is the strongest area, with 9 hand traps and several negates, and this holds up going second (about 79% chance of at least one hand trap in a six-card hand). The deck scores low on combo conversion and floor because no recorded boards exist, and it scores lowest on side deck and matchup fit because it has no side and no meta sample. Popularity was not rewarded, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo secondary (not weighted; scored with Midrange profile only). Structural ≈ 48, Going First ≈ 45, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); Illegal cap applied: 0.80*48 + 0.20*40 = 46.4, minus 12 = 34

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core present in about 94% of going-first opening hands
• 9 hand traps and negate text give strong going-second interaction
• 19 searcher-text cards and Reptile recursion support resource grind
• Multiple Ritual and Link boss options with high ATK

Weaknesses

• Illegal in TCG: nine Forbidden cards, including the Mitsurugi top end
• No side deck, so no post-side plan
• Low archetype purity (21%) across 17 sub-archetypes, weakening engine coherence
• No recorded combos, so ceiling and median are unmeasured

Critical choke points

• Ame no Habakiri no Mitsurugi is Forbidden, so the Ritual top end is unavailable in a legal build
• Mitsurugi Ritual and Mitsurugi Prayers are the only Ritual routes; both are Limited, so one copy each limits redundancy

Recommended changes

Evidence & confidence

• Verified: Legality: 9 distinct Forbidden cards run over the copy limit; Main 42 and Extra 15 counts; Side 0; Archetype core group of 17 copies, and the per-card odds from the probabilities block; Card text for the 9 hand traps and 19 searcher-text cards
• Inferred: Starter access about 0.94 from hypergeometric estimate; Going-second hand trap access about 0.79; Interaction density as a semantic read of card text; Archetype coherence from purity and sub-archetype spread
• Provisional: Meta power (no dated sample); Matchup and format fit (no tournament link)
• 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, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal in TCG, so the structural score describes the list as submitted and is not a legal-build evaluation Side deck is empty, so no side-plan evidence exists
