• Turn 1 (going first): Opening Mulcharmy or Griffoh and Ghost Ogre to draw and search Light and Darkness Ritual or Mind Shuffle, then build toward a Ritual Summon (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Nibiru / Infinite Impermanence to stop the opponent's first engine, then Mulcharmy draw-back (Inferred)
• Recovery: Mulcharmy and Ars Magna searchers plus Ragged Records of Rites to rebuild the hand from the GY (Inferred)
• After siding: Not evaluable: the deck has zero side-deck cards (Observed from evidence)

Why it scores here

The deck reliably opens its archetype core: about 92% of opening 5-card hands contain at least one Light and Darkness Ritual card, and about 87% contain a searcher, so the engine is accessible (Inferred from hypergeometric estimates). Its interaction density is high, with 14 hand traps and 9 negation-text cards, which earns credit for going-second resilience and end-board quality (Inferred from card text). The score does not reflect archetype popularity: the core-card usage stats confirm the list is real, but they add no power points. No combo boards were recorded, so ceiling and median are text-only inferences and are kept separate, and the score was not built by averaging individual card scores. The list is Illegal under the TCG ban list (over-limit Semi-Limited and Limited cards plus five Forbidden cards), so the structural read is theoretical and the final score is capped at 25.

Dimension scores

How the score was computed

Strategy profile: Balanced. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-12); illegal_cap (-6.7). Final formula: Illegal cap: theoretical structural read only. Unconstrained 0.80*54.6 + 0.20*50 - 12 (banlist exposure) = 31.7, capped at 25 for Illegal status.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and negation package (14 hand traps, 9 negation-text cards)
• Archetype core present in about 92% of opening hands
• Strong 2800-3000 ATK boss monsters

Weaknesses

• Illegal: over-limit Semi-Limited and Limited cards plus five Forbidden cards
• Zero side deck
• Heavy copy stacking and off-archetype spread (exact-name purity 13.5%)

Critical choke points

• Light and Darkness Ritual / Black Chaos ritual line depends on a few non-overlapping starters
• Forbidden Extra Deck cards (Cross-Sheep, Red-Eyes Dark Dragoon) would have to be removed, changing the Extra Deck plan
