Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Light and Darkness Ritual boss (Black Chaos / Black Luster Soldier / Magician of Dark Chaos) Ritual Summoned off a Ritual Spell, backed by Power Patron Link and Fusion extenders; Nerva the Power Patron of Creation and Link pressure through Mulcharmy and Medius/Theorealize lines
• Turn 1 (going first): Open a Ritual Spell or Black Chaos-type starter, search or Special Summon a Ritual monster, and use Mulcharmy/Medius bodies to build the Ritual or Link line, with Ash Blossom and Droll-style hand traps held as backup
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Kuriboh, Solemn Judgment/Warning and Great Gallant Bandit to stop the opponent's first board, then convert into a Ritual boss
• Recovery: Recycle through Mind Shuffle, Skull Archfiend and Theorealize searchers to refill the hand and rebuild a Ritual monster from the GY
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games in this list

Why it scores here

The deck reliably opens a starter about 25% of the time per copy-count bucket, with the archetype core (Ritual Spell, Black Chaos, Black Luster Soldier, Mulcharmy, Medius) present in about 92% of 5-card hands, so the engine is fairly accessible but the single Light and Darkness Ritual copy is the real choke point. Interaction is layered (Ash Blossom, Kuriboh, Solemn Judgment, Solemn Warning, Great Gallant Bandit, Ghost Ogre) and gives it solid going-second strength, which is why D7 and D8 score above the middle. Score is held down by a 17% exact-archetype purity across 55 Main Deck cards, a 0-card Side Deck and no recorded boards, so the combo floor and median are unknown rather than assumed. The deck is Illegal because Ash Blossom & Joyous Spring is run three times against a Semi-Limited limit of two, so the score is capped and labelled theoretical; popularity and archetype usage stats confirm the list is real but were not used to add points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53.3, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: illegal_copy_limit (-12). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 51.6; Illegal copy-limit violation applied as a -12 modifier to 39.6, then hard-capped to 30 (theoretical/structural-only)

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 coverage (Ash Blossom, Kuriboh, Ghost Ogre, Droll & Lock Bird, Solemn Judgment/Warning)
• High-ATK Ritual bosses and Link extenders for closing power
• Recursion and searchers (Mind Shuffle, Skull Archfiend, Theorealize) refill the hand

Weaknesses

• Illegal list: Ash Blossom run 3 vs limit 2
• Low archetype purity (17.1%) and many off-archetype generic cards dilute the engine
• No Side Deck, so no post-side plan
• Only one Light and Darkness Ritual Spell, a single point of failure for the Ritual engine

Critical choke points

• The single Light and Darkness Ritual copy gates the Ritual boss line
• Ash Blossom over-limit makes the list unplayable until corrected

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main / 15 Extra / 0 Side; Ash Blossom copy-limit violation (3 vs 2); Archetype purity 17.1%; copy histogram 11/10/8; Extra breakdown Link 12, Xyz 1, Fusion 2; Attack/DEF stats and banlist status for listed cards
• Observed: Core-card inclusion stats: Black Chaos 95%, Black Luster Soldier 90%, Mulcharmy Fuwalos 68%
• Inferred: Ritual engine accessibility (~25% per copy bucket per 5-card hand, 92% core group); Interaction density and going-second strength from card text; Brick and resilience estimates; Closing power from ATK stats
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no 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 match record absent no win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied deck has no title and no Side Deck
