Mitsurugi Deck #771405 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual-summon Reptile or Light and Darkness Ritual boss monsters (Ame no Murakumo, Black Luster Soldier, Black Chaos) and close with 2800-3200 ATK bodies; Synchro and Link boards from Chaos Angel, Psychic End Punisher, Enigmaster Packbit and Dyna Mondo
• Turn 1 (going first): Search a Mitsurugi or Light and Darkness Ritual Spell, then use Mitsurugi Mirror or Light and Darkness Ritual to bring out a ritual boss; hand traps are held for the opponent's turn
• Turn 2 (going second): Hold Ash Blossom, Maxx C, Droll and Artifact Lancea as hand interaction, then rebuild the board from the GY with Black Chaos or Mitsurugi Ritual
• Recovery: Recover through searchers (23 searcher-text cards, P at least one in hand of 5 is 0.92) and GY revival by Black Chaos, Skull Archfiend and Mitsurugi monsters
• After siding: Not evaluable: the deck runs 0 side cards, so there is no post-side plan

Why it scores here

The deck is scored as one system, not as an average of its cards. Its engine is split across two rituals (Mitsurugi and Light and Darkness Ritual), so starter access is only moderate: P(at least one of the 10 archetype-core cards in a 5-card opening hand) is about 0.61, which is Inferred from hypergeometric estimates. Interaction is dense and layered (6 hand traps, Forbidden Crown, Mind Mirror Force, Solemn Accusation, Spell Shattering Sword, Herald of the Arc Light), which earns the end-board and going-second dimensions. Structural power is held down by 17.3% exact-name archetype purity and 62 off-archetype copies, which add Mulcharmy, Lswarm, Phantom Knights, Galaxy-Eyes and Kuriboh pieces that compete for hand space. Popularity and usage stats were not credited: the core-card inclusion rates only confirm the list is real, and the empty combo evidence means no ceiling or median is observed. Because the list runs 3 Ame no Habakiri and 1 Number 60 (both Forbidden in OCG), it is Illegal and receives a capped, structural-only score.

Dimension scores

How the score was computed

Strategy profile: Balanced (default; no observed combo evidence to justify a strategy profile). Structural ≈ 46, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Banlist exposure (-8); Engine conflicts (-4). Final formula: Illegal cap: structural-only read 46 (Balanced); 0.80*46 + 0.20*30 = 43 before the cap; capped to 25 because the list is Illegal (Forbidden cards); Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.61 · 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

• Dense, layered interaction: 6 hand traps plus Forbidden Crown, Mind Mirror Force, Solemn Accusation and Spell Shattering Sword
• Searcher density (23 cards) gives a 0.92 chance of at least one searcher in a 5-card hand
• Strong closers in Murakumo, Black Chaos and Black Luster Soldier

Weaknesses

• Illegal list: 3 Ame no Habakiri and 1 Number 60 are Forbidden in OCG
• Two rituals plus off-archetype support split the engine (17.3% exact-name purity)
• No side deck, so no post-side adaptability

Critical choke points

• Ritual Summon lines depend on Mitsurugi Ritual, Mitsurugi Mirror or Light and Darkness Ritual; losing those cuts off the boss monsters
• Ame no Habakiri (Forbidden) occupies Main slots with no legal copies

Recommended changes

Evidence & confidence

• Verified: Illegal status: 3x Ame no Habakiri and 1x Number 60 are over the OCG copy limit (legal copies 0); Main 60 and Extra 15 fall within size rules; Side is 0; Archetype purity 17.3%, 62 off-archetype copies; Probability table and 23 searcher-text cards from evidence pack
• Inferred: Starter access ≈ 0.61 (archetype core, hand of 5); Interaction density and resilience read from card text; Going-first and going-second plans from card text
• Provisional: Meta Power (null) and matchup fit: no dated meta sample or 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 record are absent No win-rate or brick-rate telemetry; going-first and going-second splits are unobserved Meta Power is provisional without a dated metagame sample Side deck is empty; no post-side evaluation is possible
