Light and Darkness Ritual Deck #772820 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Toolbox, Stun
• Format: ocg

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos or Black Luster Soldier with Light and Darkness Ritual, then close with 3000-ATK bodies (Black Chaos, Black Skull Dragon, Albion, Dragon that Devours the Dogma); Fusion Summon Albaz Dragon-line Fusions via Fallen of Albaz, Branded Fusion, Blazing Cartesia and Super Polymerization
• Turn 1 (going first): Search Light and Darkness Ritual or Ragged Records, Ritual Summon Black Chaos from hand/GY or Fallen of Albaz into a Fusion; hold Ash, Droll and Impermanence for the opponent's first response (Inferred)
• Turn 2 (going second): Open with hand traps (Ash, Droll, Impermanence, Nibiru, Kuriboh) to stop the opponent's first summon, then rebuild a Ritual or Fusion line from the GY (Inferred)
• Recovery: Mind Shuffle and Ragged Records recover Ritual spells and monsters; Skull Archfiend and Black Skull Dragon return bodies from GY and banish zones (Inferred)
• After siding: Not available: the deck runs no Side Deck, so post-side adaptation is structurally absent

Why it scores here

The deck reliably opens a core engine most of the time: the archetype core group (19 copies) has an estimated 0.86 chance of at least one copy in a 5-card opening hand, and 16 searcher-text cards add redundancy (Inferred). It converts that access into strong closing bodies at 3000 ATK or higher, and it runs nine hand traps plus Solemn, Droll and Impermanence for layered interaction, so its end-board is strong on paper. Its weaknesses are a low exact-name archetype purity (20%), a spread of sub-archetypes (Despia, Mulcharmy, Branded, Dogmatika, Albaz) that dilutes the engine, and an empty side deck. The score is built from consistency, median output and interaction on the system, not from averaging card scores and not from popularity, which earned no points since there is no meta-share data. The deck is Illegal (Ash Blossom and Super Polymerization at 3 copies against a Semi-Limited limit of 2), so the structural score of about 53 is capped to 30 and labelled theoretical only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-5); no Side Deck (-3); sub_archetype_dilution (-2). Final formula: Pre-cap: 0.80*Structural(56) + 0.20*TournamentReliability(42) + modifiers(-10) = 43; Illegal legality cap applied to 30 (theoretical structural only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is reachable in most opening hands (0.86, Inferred)
• Strong 3000-ATK closing bodies and layered interaction (Verified stats, Inferred semantics)

Weaknesses

• Illegal copy counts on Ash Blossom and Super Polymerization
• Low exact-name purity (20%) and spread across sub-archetypes
• No side deck
• No recorded combos to confirm median output

Critical choke points

• Light and Darkness Ritual count is 2, so one dead copy removes the main Ritual enabler (Inferred)
• Ritual monsters need a Ritual Spell in hand or GY, which the Ragged Records and Mind Shuffle loop depends on (Inferred)

Recommended changes

Evidence & confidence

• Verified: Main 60 and Extra 15 counts are within size rules; Ash Blossom and Super Polymerization are over copy limit (3 vs 2); Attack and DEF stats of the 3000-ATK bodies; Archetype core group of 19 copies and P(at least one) = 0.86
• Inferred: Starter access and redundancy estimates; Interaction density from card text; Going-first and going-second plans
• Provisional: Meta Power is null; Matchup fit (D13) and archetype share are unavailable
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot match record are absent No win-rate telemetry exists, so going-first, going-second and matchup signals are Inferred or Unknown Deck is Illegal, so the score is structural and theoretical only Meta Power is Provisional unless a dated metagame sample is supplied
