Light and Darkness Ritual Deck #770267 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 49 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Ritual-summon a Black Chaos or Black Luster Soldier-class boss (Magician of Dark Chaos - Black Chaos, Black Luster Soldier, Black Chaos) through Light and Darkness Ritual, then press the board with 2800-3000 ATK monsters.; Link and Fusion finishers (Firewall Dragon, Perfectron Hydradrive Dragon, Timaeus, Dark Magician of Destruction) once the ritual board is established.
• Turn 1 (going first): Open a starter (Griffoh, Dark Magician Girl, Black Chaos, Spellbook of the Grand Circle, Mind Shuffle or Light and Darkness Ritual), search the ritual line, and set up Ash Blossom or Droll as interaction on the opponent's turn. Full conversion depends on the Extra Deck and is not verifiable from this list.
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Maxx C and Droll as hand-trap interaction, then convert on the next turn. Hand-trap density is 5 cards, with about 0.50 probability of at least one in a six-card opening hand.
• Recovery: Recover through the searcher density (23 searcher-text cards, about 0.97 probability of at least one in an opening hand) and the Graveyard ritual-monster reuse. No recorded recovery line exists.
• After siding: Not evaluable. The side deck is empty, so there is no post-side plan.

Why it scores here

The deck is Illegal in OCG: five cards (Magicians' Souls, Charmer Quartet in Bloom, Red-Eyes Dark Dragoon, Cross-Sheep, Protectcode Talker) are Forbidden and run at one copy each, so the score is a theoretical, structural-only read capped low. Structurally the list reliably opens a starter with about 0.83 probability for the archetype core and about 0.97 for at least one searcher-text card, and it carries real interaction through Ash Blossom, Effect Veiler, Droll and Maxx C. The ritual boss package (Black Chaos, Black Luster Soldier, Magician of Dark Chaos - Black Chaos) gives a high ceiling on paper, but no recorded boards exist, so conversion and median output are inferred from text alone. The score was built from consistency, interaction and closing power on the system as a whole, not from averaging card scores, and archetype popularity (usage stats show the core in most lists) earned no points by itself. The empty side deck and the missing post-side plan further depress the score.

Dimension scores

How the score was computed

Strategy profile: Combo weights (primary) with the Toolbox profile considered; Combo weights used for the structural calculation. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); empty side deck (0). Final formula: Illegal deck: theoretical cap applied. Structural 52 (Combo weights) → 0.80·52 + 0.20·45 = 50.6 pre-modifier; modifiers total −12 → 38.6; capped to 30 for illegal status. Meta provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · 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 searcher text (23 cards) gives high starter access
• Five hand traps and several removal/negation texts provide layered interaction
• Ritual bosses (Black Chaos, Black Luster Soldier, Magician of Dark Chaos - Black Chaos) give a high ceiling
• Strong core inclusion for the archetype: Magician of Dark Chaos - Black Chaos (97%) and Black Luster Soldier (91%) in the usage stats

Weaknesses

• Illegal in OCG: five Forbidden cards at one copy each
• Empty side deck: no post-side plan
• Low archetype purity (17%) across mixed sub-archetypes
• No recorded combos, so floor and median are unknown
• Several core usage-stat cards are absent (Mulcharmy Fuwalos, S:P Little Knight, Ragged Records of Rites, Chaos Angel)

Critical choke points

• Light and Darkness Ritual must be live to reach the ritual boss package
• Extra Deck Link/Fusion access, with 15/15 Extra slots already spent on cards that include Forbidden copies

Recommended changes

Evidence & confidence

• Verified: Illegal status: five Forbidden cards at one copy each (legality block); Main 49 / Extra 15 / Side 0 within OCG size rules; Ash Blossom Semi-Limited at 2 copies, legal; Usage stats: Magician of Dark Chaos - Black Chaos 97%, Black Luster Soldier 91%
• Inferred: Starter access ≈ 0.83 for the archetype core in opening 5; Searcher density ≈ 0.97 in opening 5; Hand-trap odds ≈ 0.50 in a six-card opening going second; Ritual boss ceiling from card text alone
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit
• Data gaps: No combos supplied: 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 and matchup rates unknown Empty side deck: no post-side plan data Meta Power is provisional without a dated metagame sample
