Light and Darkness Ritual Deck #773274 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ritual-summoned Black Chaos and Black Luster Soldier boards, backed by Fusion and Synchro bosses from the Extra Deck (Inferred from card text); Synchro and Fusion bosses such as The Crimson King, Chaos Angel and Despian Quaeritis, once the Ritual starter goes off (Inferred)
• Turn 1 (going first): Light and Darkness Ritual or Ragged Records / Mind Shuffle to find the Ritual monster, then Ritual Summon, with Ash Blossom and Droll & Lock Bird held as interaction (Inferred)
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Maxx C, Droll & Lock Bird) to answer the opponent's first board, then rebuild a Ritual or Synchro line (Inferred)
• Recovery: Searchers (15 copies with search text) and Mulcharmy draw effects to rebuild a hand after an interruption; GY Ritual recursion via Skull Archfiend of Chaos (Inferred)
• After siding: No side deck is present, so no post-side plan can be scored; this is a major gap.

Why it scores here

The list is Illegal: Branded in High Spirits runs 3 copies against a limit of 1, Albion the Branded Dragon (Forbidden) is run, and the Extra Deck holds 18 cards against a 15-card cap, so it does not receive a normal score. The structural read is that the Ritual starter (Light and Darkness Ritual, 2 copies) has only an 18% chance of appearing in a 5-card opening hand, and the archetype core is present at 97% but the exact-name purity is only 22.9% across Mulcharmy, Branded, Albaz, Chaos and Stardust cards. Interaction density is reasonable, with 7 hand traps and 21 removal-text cards, which earns credit for going-second resilience. There are no recorded combos, no side deck and no tournament data, so the offensive and floor scores rest on card text only. The score comes from consistency and interaction on the system, not from averaging card scores and not from archetype popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 47, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); extra deck oversize (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + modifiers(-10) = 35.6, then capped at 30 because the list is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.18 · 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

• Core archetype cards are present at 97% opening-hand availability (Verified draw odds)
• Seven hand traps and 21 removal-text cards give layered interaction (Verified flags, Inferred use)
• Searcher text on 15 cards supports recovery (Inferred)

Weaknesses

• Illegal list: copy-limit and Forbidden-card violations (Verified)
• Extra Deck is 18 cards, over the OCG cap of 15 (Verified)
• No side deck (Verified)
• Low exact-name purity at 22.9% weakens engine coherence (Verified count, Inferred effect)

Critical choke points

• Light and Darkness Ritual (2 copies) is the only Ritual spell route; P(in opening hand) ≈ 0.18 (Inferred)
• Albion the Branded Dragon is Forbidden and cannot be played in OCG (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality violations: Branded in High Spirits 3 copies vs limit 1, Albion Forbidden, Extra Deck 18 vs 15; Card stats and text read from the resolved card list; Archetype core present ≈ 97% (hypergeometric)
• Inferred: Ritual-starter access ≈ 18% in a 5-card hand; Brick and redundancy estimates from copy histogram and card roles; Interaction breadth from text roles; Going-first and going-second plans from card text
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (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 side deck — post-side plan cannot be scored no win-rate telemetry exists in YGOVN (going-first/second, matchup, brick/starter rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
