Light and Darkness Ritual Deck #772866 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Light and Darkness Ritual / Dark Magician boss beatdown (Black Luster Soldier, Black Chaos, Magician of Dark Chaos) with Extra Deck link and fusion support; Dark Magician fusion and synchro boards (The Dark Magicians, Dark Magician of Destruction, Master of Chaos, Chaos Angel is not run)
• Turn 1 (going first): Open a searcher and hand-trap pair, then search or summon a Light and Darkness Ritual boss through Light and Darkness Ritual and tributes (Inferred from card text; no recorded boards)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Kuriboh and Solemn cards to stop the opponent's first board, then Ritual or Fusion into a boss (Inferred)
• Recovery: Skull Archfiend of Chaos and Black Chaos recycle the GY and banished Ritual monsters back to the Deck; Mind Shuffle and Magical Circle search the next piece (Inferred from card text)
• After siding: Not evaluable: side_count is 0, so there is no post-side plan in the list

Why it scores here

The deck has a dense core: 20 archetype-core copies give about a 0.90 chance of at least one in a 5-card opening hand, and 21 searcher-text cards give about 0.92, so the engine usually starts. Its interaction suite is broad, with 15 negation-text cards, 7 hand traps and 24 removal-text cards, which earns the interaction and interruption scores. Its ceiling comes from Light and Darkness Ritual bosses rated at 3000 ATK, but no recorded boards exist, so combo conversion and floor are text-only Inferred estimates and are scored low-to-mid. The list is only 19.7% exact archetype name and spreads across Dark Magician, Kuriboh, Prophecy, Chaos and Solemn cards, so the engine is less coherent than its core suggests, and it runs no side deck. Popularity and usage stats confirmed that the list is real and accessible, but they did not add points, and the score did not come from averaging card scores. The list is Illegal (3 copies each of two Semi-Limited cards), so the 30 score is a structural cap, not a normal Final Contextual score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no secondary blend applied. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-4); No side deck (-4). Final formula: Illegal cap applied: normal formula would be 0.80*Structural(57) + 0.20*TournamentReliability(50) + modifiers(-8) ≈ 48; capped to 30 because the list is Illegal (theoretical/structural-only). Meta Power provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher and archetype core (about 0.90 to open a core card)
• Broad negation and hand-trap suite (15 negation-text, 7 hand traps)
• High-ATK ritual and fusion bosses at 2800 to 3000 ATK

Weaknesses

• Illegal: two cards over their Semi-Limited copy caps
• Engine conflicts: Dark Magician, Ritual, Chaos, Prophecy and Solemn plans compete for the same slots
• No side deck
• Only 19.7% exact archetype name purity

Critical choke points

• Light and Darkness Ritual (2 copies) and Mind Shuffle are the core engine links; losing both removes the ritual route
• Dependence on Black Chaos and Magician of Dark Chaos for the boss turn

Recommended changes

Evidence & confidence

• Verified: Main 56, Extra 15, Side 0 counts (OCG size rules 40-60 / 0-15 / 0-15); Two copy-limit violations: Ash Blossom and Dominus Impulse at 3 copies each, Semi-Limited limit 2; Limited cards Droll & Lock Bird, S:P Little Knight and Solemn Judgment are each run once; Usage: Black Luster Soldier 90.9% and Magician of Dark Chaos 95.4% inclusion
• Inferred: Hypergeometric opening-hand estimates (0.90 core-group, 0.92 searcher-group, 0.57 hand-trap-group going second); Ritual boss turn and recovery plans from card text; Hand-trap and interaction density reads from text
• Provisional: Meta power and matchup fit (no dated metagame sample)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Side deck is empty, so no post-side evaluation is possible Meta Power is provisional without a dated metagame sample
