Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ritual-summon a Mitsurugi Reptile boss (Ame no Murakumo no Mitsurugi, 3200 ATK, whose on-summon effect destroys all opposing monsters) via Mitsurugi Ritual or Mitsurugi Mirror, then close with Link/Xyz beats; Link and Xyz extra-deck monsters (Gorgon, Super Starslayer TY-PHON, Divine Arsenal AA-ZEUS) converting a cleared board
• Turn 1 (going first): Search a Mitsurugi monster or Ritual spell with Mitsurugi Prayers, Mikoto or Kusanagi, then build a Ritual Summon of a Reptile boss while holding Ash Blossom and Droll as interaction
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Solemn Warning and Ghost Ogre to stop the opponent's first summon, then Ritual Summon through the cleared board
• Recovery: Reptile recursion (Futsu no Mitama, Mitsurugi Great Purification) and Mitsurugi searchers rebuild the Ritual line from the GY and banish zone
• After siding: Not evaluable: the deck runs an empty Side Deck (0 of 15 allowed), so there is no post-side plan

Why it scores here

The deck reliably opens a Mitsurugi engine: 30 of 55 Main Deck cards are core archetype cards, so P(at least one core card in a 5-card opening hand) is about 0.98, and 17 searcher-text cards give P(at least one) of about 0.86 for a searcher in hand. Conversion relies on Ritual-summoning a Reptile boss, which needs a specific starter, so its single-starter odds are only about 0.25 per 3-copy card. Interaction is the strongest pillar: 11 hand traps, 12 negation-text cards and 16 removal-text cards give layered answers both going first and going second, which supports the going-second read. Scoring is on the system, not an average of card scores, and archetype popularity (usage statistics showing the core is standard) was not given points beyond confirming the list is real. The deck is Illegal: four copy-limit or Forbidden violations, including a Forbidden Extra Deck card and three copies of Limited cards, so the score is capped at 30 as a theoretical, structural-only read. No combos, guides, tournament link or Side Deck exist, so the combo and meta claims are Inferred or Provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); illegal_cap (-12). Final formula: Illegal deck: normal formula 0.80*Structural + 0.20*TournamentReliability = 54.6, then banlist modifier -12 gives 42.6; capped at 30 per the Illegal rule. Theoretical/structural-only read (Meta Provisional, null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Layered hand-trap and negation suite (11 hand traps, 12 negation-text cards)
• Archetype core is almost always present in opening hands (P of about 0.98)
• Recursion through Reptile monsters and the GY gives a second route after disruption

Weaknesses

• Illegal list: 4 copy-limit or Forbidden violations
• Empty Side Deck, so no post-side plan
• No recorded boards, so the combo ceiling and floor are unmeasured
• Ritual starters are single-copy-dependent with low individual hit rates

Critical choke points

• Mitsurugi Ritual or Mitsurugi Mirror as the sole Ritual enabler for the main boss line
• Forbidden Bagooska in the Extra Deck is a dead slot as built

Recommended changes

Evidence & confidence

• Verified: Illegal status: 4 copy-limit or Forbidden violations (Pre-Preparation of Rites, Mitsurugi Prayers, Ash Blossom, Bagooska); Main 55 and Extra 15 are within size rules; Side Deck count is 0 of 15 allowed; Banlist status per card (Limited, Semi-Limited, Forbidden); Usage stats: 21 archetype rows, 15 of 20 core cards present (75%)
• Inferred: Hypergeometric opening-hand odds for starters, core and searcher groups; Hand-trap and negation coverage from card text; Going-first and going-second read from text and interaction density; Board-wipe and Link/Xyz closing power from card text
• Provisional: Meta Power is null: no dated metagame sample is supplied; Matchup fit and format fit (D13 at 50)
• Data gaps: Illegal list: copy-limit and Forbidden violations prevent a normal Final score 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 exists in YGOVN No Side Deck: post-side plan cannot be evaluated Meta Power is Provisional unless a dated metagame sample is supplied
