Light and Darkness Ritual Deck #770226 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 41 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Black Luster Soldier - Soldier of Light and Darkness via Light and Darkness Ritual, then convert the 3000-ATK boss into board pressure; Extra Deck Synchro/Link/Fusion boards (Ecclesia and the Dark Dragon, Enigmaster Packbit, Golden Cloud Beast - Malong, Dharc, Lyna, Bucephalus II) once the Ritual engine has resources
• Turn 1 (going first): Open with Ragged Records of Rites or Nadir Servant to fetch a Ritual Spell, play Griffoh or Mind Shuffle for a search, then Light and Darkness Ritual into Black Chaos or Black Luster Soldier
• Turn 2 (going second): Hold Ash Blossom and Droll & Lock Bird to answer the opponent's first search or Special Summon, then rebuild through Mind Shuffle and Skull Archfiend of Chaos
• Recovery: Skull Archfiend of Chaos and the Ritual monsters recycle from the GY; Ragged Records of Rites and Mind Shuffle refill the hand from the Deck
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games

Why it scores here

The score reflects the deck as a system: the Light and Darkness Ritual core (about 97% of archetype-core cards are in the opening five-card hand per the hypergeometric estimate) gives it a reliable starter density, and the 3000-ATK Ritual boss plus a layer of hand traps (Ash Blossom, Droll and Lock Bird, Maxx C) and negation text provides real going-second interaction. Conversion is the weak point: no recorded boards exist, so the ceiling and median are text-only inference and are scored conservatively. The deck is capped to 30 because Albion the Branded Dragon is Forbidden in OCG and is run once, which makes the list Illegal; the structural read (about 56) is shown for reference only. Archetype popularity (the core is present in the list) earned no points beyond the consistency estimate, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal list cap (-24). Final formula: Illegal cap: 0.80*Structural(56) + 0.20*TournamentReliability(45) = 54, then -24 Illegal cap = 30 (Meta provisional, not scored)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · 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

• Dense archetype core (about 97% of core cards in hand five)
• Layered hand traps and negation text for going second
• Two 3000-ATK ritual bosses with recursion routes
• Full Extra Deck with multiple summon routes

Weaknesses

• Illegal: Albion the Branded Dragon is Forbidden and run once
• No Side Deck
• No recorded combos, so conversion and floor are unverified
• Ritual starters are thin at 2-3 copies each

Critical choke points

• Light and Darkness Ritual (2 copies) is the only Ritual Spell route to the bosses
• Ash Blossom and Droll and Lock Bird are the only answers to going-second searches

Recommended changes

Evidence & confidence

• Verified: Albion the Branded Dragon is Forbidden in OCG and run once (Illegal); Main 41 and Extra 15 are within the size rules; Ash Blossom and The Fallen and The Virtuous are at legal Semi-Limited copies (2); Core inclusion: Magician of Dark Chaos - Black Chaos 97%, Black Luster Soldier 91%, Griffoh 73%
• Inferred: Starter probabilities from hypergeometric estimates; Interaction and resilience reads from card text; Going-first and going-second plans from text and draw odds
• Provisional: Meta Power is null; format fit (D13) lacks a dated metagame sample
• Data gaps: No combos supplied: floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry exists in YGOVN Side Deck is empty, so post-side behaviour is unknown Meta Power is Provisional unless a dated metagame sample is supplied
