Mitsurugi Deck #773574 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual Summon Ame no Murakumo no Mitsurugi (3200 ATK, destroys all opponent monsters on summon) or Ame no Habakiri no Mitsurugi (2400 ATK, -800 ATK to opponent monsters), with Mitsurugi search chains feeding the Ritual Spells.; Extra Deck follow-up via Link/Xyz/Fusion (Dark Magician of Destruction, Worldsea Dragon Zealantis, Super Starslayer TY-PHON, Ragnaraika) once the Reptile board is established.
• Turn 1 (going first): Pre-Preparation of Rites or a Mitsurugi searcher (Aramasa, Saji, Kusanagi, Lamia, Wousu) for a Ritual Spell, then Mitsurugi Ritual or Mirror into a Ritual boss, backed by Ash Blossom / Ghost Ogre hand traps.
• Turn 2 (going second): Six-card hand with a hand trap (Ash Blossom, Ghost Ogre, Maxx C, Droll) to protect the first Reptile engine, then a Ritual boss through the opponent's remaining board.
• Recovery: Searchers and GY-summon effects (Futsu no Mitama, Mitsurugi Prayers, Mitsurugi Mirror) rebuild the Reptile board from the Graveyard and banishment.
• After siding: None: side_count is 0, so no post-side plan can be evaluated.

Why it scores here

The deck reliably opens its engine: the 24-copy Mitsurugi core gives a Inferred ~99% chance of at least one core card in a 5-card opening hand, and 16 searcher-text cards push the chance of a searcher to about 94%. Conversion is strong on paper because the Ritual bosses (Murakumo at 3200 ATK, Habakiri at 2400, Futsu at 2000 with a 3400 DEF body) can end a board in one summon. The median output is not measured, since no recorded boards exist, so the floor is scored conservatively at 50. Interaction is layered through hand traps (Ash Blossom, Ghost Ogre, Maxx C, Droll), Dominus Impulse, and Mitsurugi Great Purification. The score is held back by the absence of a side deck, by Droll and GY-banish weakness flagged in the guide, and by six off-archetype Mulcharmy draw cards that conflict with a Reptile board. Score comes from the system (search, ritual conversion, interaction, closing ATK), not from averaging card scores, and not from the archetype's popularity: no meta-share or tournament data counted toward the result.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 64, Going First ≈ 64, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-1); no side deck (-2); engine conflict (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (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 from a 24-copy archetype core and 16 searchers
• Ritual bosses with high ATK and board-wipe or ATK-reduction effects
• Layered interaction: 8 hand traps, negations, and removal text
• Redundant searchers and GY recursion support resilience after one interruption
• Extra Deck offers multiple link-summon closers

Weaknesses

• No side deck, so there is no post-side plan
• Droll & Lock Bird and GY-banish lines are a single choke point, as the guide notes
• Only 31% exact-name archetype purity; Mulcharmy cards conflict with the Reptile board
• No recorded boards, so the median and floor cannot be confirmed
• Two Limited single-copy cards carry banlist exposure

Critical choke points

• Droll & Lock Bird stopping Mitsurugi searches for the rest of the turn
• Graveyard or banish-based interruption removing Reptile recursion and Ritual material
• Lack of a side deck leaving no answer to a hard counter-meta

Recommended changes

Evidence & confidence

• Verified: Legal under BanMasterDuel: 40 main, 15 extra, 0 side; all restricted copies within limits; Card text for Murakumo, Habakiri, Futsu, Droll, Maxx C, and Ash Blossom; Usage stats: Mitsurugi core cards at 84–100% inclusion
• Observed: Guide note that the deck is cheap, has strong search, and fears Droll
• Inferred: Starter access (≈99% core, ≈94% searcher) from hypergeometric estimates; Interaction density and going-second answers from card text; Closing power from end-board ATK values; Structural score and final blend
• Provisional: Meta Power (null, no dated meta sample); D13 matchup fit (neutral placeholder); Median output (no recorded boards)
• 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: going-first/second, matchup, and brick rates are Inferred Meta Power is Provisional without a dated metagame sample Side deck is empty, so no post-side evidence exists
