Light and Darkness Ritual Deck #765290 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±8 · Confidence: Low)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Black Luster Soldier / Magician of Dark Chaos - Black Chaos, then convert the board with 3000-3000+ ATK monsters and Link/Fusion/Synchro follow-up (Chaos Angel, Red-Eyes Dark Dragoon, Gottoms); Mulcharmy draw-engine grind into Link and Fusion Extra Deck pressure (Mediclius, Fancy Ball, Artmage Diactorus)
• Turn 1 (going first): Open Light and Darkness Ritual / Griffoh / Mulcharmy starters, search the Ritual Spell or Ritual monster, and Ritual Summon Black Chaos or BLS; hold Ash Blossom and Droll as protection (plan is structurally sound but relies on an illegal list at 3 Ash Blossoms)
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll, Kuriboh) to stop the opponent's first board, then Ritual Summon through the remaining Ritual and Power Patron lines (inferred from card text, no recorded boards)
• Recovery: Recover via Mulcharmy draw effects, Griffoh/Theorealized Medius searches, and Skull Archfiend of Chaos GY recursion (inferred from card text)
• After siding: Not available: the deck has zero Side Deck cards, so no post-side adaptation can be evaluated

Why it scores here

The deck is scored on its system, not by averaging its cards. Its archetype core (23 copies of the Light and Darkness Ritual / Mulcharmy / Ars Magna family) has an estimated 98.9% chance of at least one piece in a 5-card opening hand, and its searcher text (18 copies) gives about 95.5% access, so the engine is reliably reachable (Inferred). Interaction is dense: 5 hand traps and 6 negation-text cards, led by Ash Blossom, Droll and Kuriboh, give it a credible going-second plan (Inferred from card text). Conversion is capped by the absence of recorded boards, so the ceiling (Black Chaos, Black Luster Soldier, Chaos Angel at 3500 ATK) and the median cannot be separated from the card text alone. The deck is Illegal: it runs 3 copies of Ash Blossom & Joyous Spring against a limit of 2, and it has no Side Deck. Popularity and usage data show the list is a real, accessible build, but they earn no power points. Because the list is illegal, the final score is capped and labelled theoretical/structural-only.

Dimension scores

How the score was computed

Strategy profile: Combo profile used; Midrange not blended in. Structural ≈ 54, Going First ≈ 52, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure_over_limit (-20). Final formula: Illegal cap: 0.80*Structural(54) + 0.20*TournamentReliability(45) = 52.2, then modifiers -20 -> 32; theoretical/structural-only, Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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

• Highly reliable archetype-core access (P>=1 in opening hand 0.989, Inferred)
• Layered hand traps and negation text (5 hand traps, 6 negation cards) for going-second interaction (Inferred)
• Strong boss monsters at 3000-3500 ATK and a full 15-card Extra Deck with several access routes (Verified stats)

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring runs 3 copies against a limit of 2 (Verified)
• No Side Deck, so no post-side plan can be evaluated (Verified)
• Low exact-archetype purity (21.4%) with 44 off-archetype copies, which weakens engine cohesion (Verified composition)
• No recorded boards, so ceiling and median cannot be measured (Verified gap)

Critical choke points

• Light and Darkness Ritual / Ritual monster access to Black Chaos or BLS (inferred from card text)
• Ash Blossom copy count: the list is illegal until it runs 2 copies (Verified)

Recommended changes

Evidence & confidence

• Verified: Main 41 / Extra 15 / Side 0 within TCG size rules; Ash Blossom & Joyous Spring: 3 copies vs legal limit 2 (Semi-Limited) = Illegal; Droll & Lock Bird at 2 copies is legal (Semi-Limited limit 2); Copy histogram: 18 cards x3, 12 cards x2, 11 cards x1 = 41; Extra Deck: 9 Link, 4 Fusion, 2 Synchro; Archetype exact-name purity 21.4%
• Inferred: P(>=1 archetype-core card in 5-card hand) = 0.989 (hypergeometric); Searcher access P(>=1) = 0.955; Going-second hand-trap coverage P(>=1 in 6) = 0.567; Engine conversion and interaction quality from card text (Ritual/Power Patron routes); Recovery via Mulcharmy draw and GY recursion
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (archetype context only, no tournament link)
• Data gaps: no combos supplied: combo floor/median/ceiling is text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry: going-first/second, matchup and brick rates unknown Meta Power provisional without a dated metagame sample Deck has no Side Deck, so D12 cannot be measured
