Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Control, Ritual, Synchro/Fusion
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos or Black Luster Soldier via Light and Darkness Ritual, then extend into Synchro/Fusion boss monsters; Synchro and Fusion bosses (Enigmaster Packbit, Ecclesia and the Dark Dragon, The Dragon that Devours the Dogma) after Fallen of Albaz/Dogmatika starters
• Turn 1 (going first): Open a Ritual starter or searcher line (Mind Shuffle, Skull Archfiend, Light and Darkness Ritual) and protect it with Ash Blossom, Droll, and Solemn-series traps
• Turn 2 (going second): Use hand traps (Ash Blossom, Maxx C, Droll and Lock Bird, Solemn Judgment) to break the opponent's starter, then Ritual Summon through the gap
• Recovery: Mind Shuffle and searchers rebuild a Ritual Monster and the Ritual Spell from the Deck; Skull Archfiend recurs from the GY
• After siding: No side deck is registered (side_count 0), so no post-side plan can be evaluated

Why it scores here

The score comes from the system, not from averaging card scores. The archetype core (22 copies) has about a 93% chance of at least one piece in a 5-card opening hand, and the searcher text group (15 copies) about 81%, so the engine usually becomes live on turns 1 to 2. Ritual conversion into Black Chaos or Black Luster Soldier is strong, and the Extra Deck gives several Synchro and Fusion bosses. Interaction is dense: Ash Blossom x2, Maxx C, Droll and Lock Bird, Solemn Judgment, Solemn Warning and Solemn Accusation cover both the going-first and going-second turns. Two points weigh against it. First, the deck is illegal: Branded in High Spirits is run 3 times against a limit of 1, and Albion the Branded Dragon is a Forbidden card in the Extra Deck. Second, there are no recorded boards, so the floor, median and ceiling are text-only inference. Popularity was not used: the archetype core is present (84.6% of usage-core cards), but that only confirms the list is real. The score is capped at 30 because the list cannot be legally played.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57.6, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist_exposure (-12); illegal_cap (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 55.7 before modifiers; modifiers -12 gives 43.7; illegal-deck cap sets final to 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core engine is highly accessible on turns 1 to 2 (93% for the archetype core in a 5-card opening hand)
• Layered interaction covers both going-first and going-second turns (Ash x2, Maxx C, Droll, Solemn x3)
• Strong Ritual and Synchro closers (Black Chaos, Black Luster Soldier, Enigmaster Packbit)
• Searchers give redundancy across Ritual starters

Weaknesses

• Illegal list: copy-limit violation on Branded in High Spirits and a Forbidden card (Albion) in the Extra Deck
• No side deck, so no best-of-3 adaptation
• No recorded boards, so the combo ceiling and median are unverified
• Single-copy Light and Darkness Ritual is a single point of failure for the Ritual engine

Critical choke points

• Light and Darkness Ritual (1 copy) is needed to Ritual Summon the Black Chaos and Black Luster Soldier boss line
• Missing core cards (S:P Little Knight, Chaos Angel) reduce route redundancy
