Mitsurugi Deck #754591 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status: Illegal. 11 violation(s).

Identity & game plan

• Win condition: Ritual Summon Reptile boss monsters (Ame no Murakumo no Mitsurugi, Lava Golem, Ruler of the End of the World) through Mitsurugi Ritual and Mitsurugi Ritual-family spells, then press with the board; Link and Xyz extra-deck bosses (Ragnaraika Selene Snapper, Tornado Dragon, Super Starslayer TY-PHON) once the Ritual board is established
• Turn 1 (going first): Turn 1 search through Mitsurugi monsters and Mitsurugi Prayers or Mitsurugi Ritual, then Ritual Summon a Reptile boss; the legal list has no complete deterministic opening (no combo data supplied)
• Turn 2 (going second): Use the six-card hand to hold Ash Blossom, Droll and Dominus Impulse for interaction, then rebuild a Ritual board; Forbidden Dimension Shifter and Called by the Grave cannot be run in a legal list
• Recovery: Recover through Pre-Preparation of Rites, Futsu no Mitama no Mitsurugi and Mitsurugi no Miko, Wousu; Ragged Records and Mitsurugi Mirror return Ritual monsters from the GY (Inferred from card text)
• After siding: Not evaluable: the deck has an empty Side Deck (0 cards), so no post-side plan exists

Why it scores here

The deck's reliable opening rests on its Mitsurugi core: the hypergeometric estimate puts at least one archetype-core card in a 5-card opening hand at about 0.97 (Inferred), so the Ritual engine is usually reachable on turn 1 or 2. Its ceiling is a Ritual boss plus Ame no Murakumo's board-wipe effect, and its interaction (Ash Blossom, Droll and Lock Bird, Dominus Impulse, Mitsurugi Great Purification, Lightning Storm) gives the deck a layered end board. Those strengths are offset by an illegal list: six Forbidden cards and several Limited or Semi-Limited copy overages, which caps the evaluation as theoretical and structural only. No combo recordings, tournament results or side deck exist, so median output, going-second performance and matchup fit are estimates. The score comes from the deck's consistency, median output and interaction taken together as a system; it is not the average of the card scores, and the archetype's popularity earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary, not separately weighted. Structural ≈ 50, Going First ≈ 48, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-12); empty_side_deck (0); illegal_cap (-10). Final formula: Illegal cap: 0.80*Structural(50) + 0.20*TournamentReliability(35) + Modifiers(-12) = 35, capped to 25 for an illegal list; theoretical and structural only, Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · 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

• Strong archetype core with a high opening-hand presence (about 0.97 for at least one core card)
• Layered interaction in the main deck: Ash Blossom, Droll and Lock Bird, Dominus Impulse, Great Purification and Lightning Storm
• Several 3000-plus ATK Ritual and Xyz bosses with a Ritual board-wipe effect

Weaknesses

• Illegal as built: six Forbidden cards and several copy-limit overages
• Main deck of 57 cards is bloated and carries 12 cards at 3 copies
• Empty side deck: no post-side plan
• No combo or tournament evidence to confirm median output or matchup fit

Critical choke points

• Mitsurugi Ritual and the Ritual boss must both be live for the main engine to close
• The Forbidden board-breakers cannot be legally replaced by a copy in the current list, so the closing plan depends on the Ritual boss

Recommended changes

Evidence & confidence

• Verified: Illegal status: six Forbidden cards and several Limited and Semi-Limited copy overages in the legality block; Main size 57, Extra 15, Side 0 against the TCG size rules; Hypergeometric archetype-core probability 0.966 with 27 core copies
• Inferred: Ritual engine accessibility and brick estimate from composition and text; Interaction quality from card-text semantic reads; Going-second hand-trap estimate of about 0.50
• Provisional: Meta Power (null), matchup fit and tournament reliability, pending a dated meta sample
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second, matchups or brick rates Side deck is empty, so no post-side evidence exists Deck title is null
