Light and Darkness Ritual Deck #772769 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Medium)

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

Legality

Main 58 / Extra 13 / Side 0 — status: Legal with warning. 3 violation(s).

Identity & game plan

• Win condition: Fusion Summon Shaddoll boss monsters (El Shaddoll Meshahrail / Shekhinaga / Winda) via El Shaddoll Fusion and Shaddoll Fusion, then convert the board with attack pressure from 2800-3000 ATK monsters.; Ritual Summon Black Luster Soldier or Magician of Dark Chaos - Black Chaos (3000 / 2800 ATK) with Light and Darkness Ritual, plus Skull Archfiend and Black Chaos as extenders.
• Turn 1 (going first): Search a Shaddoll Fusion or El Shaddoll Fusion through Ragged Records of Rites / Mind Shuffle / Void Unleashing, Fusion Summon a Shaddoll boss, and hold Solemn or Evenly Matched for protection.
• Turn 2 (going second): Use Droll & Lock Bird, Solemn Judgment, and the fusion negate effects (Shekhinaga, Grysta, Apkallone) to interrupt the opponent's summon and establish a Fusion board.
• Recovery: Shaddoll recursion from the GY and banish zone (Naelshaddoll Ariel, Shaddoll Hedgehog, Reeshaddoll Wendi, Shaddoll Squamata) rebuilds Fusion materials and re-enables the searcher chain.
• After siding: No Side Deck is present, so there is no post-side plan; this is scored as a structural weakness.

Why it scores here

The deck opens a functional plan most of the time because its Shaddoll Fusion and El Shaddoll Fusion starters are backed by 11 searcher-text cards, giving a 0.67 chance of at least one searcher in the opening 5 (hypergeometric, Inferred). Its ceiling is credible from text alone: the Shaddoll boss monsters convert a Fusion starter into 2600-2800 ATK bodies with negation attached, but no recorded boards exist, so the median output is scored lower and labeled Inferred. Interaction is the strongest part of the system: Solemn Judgment, two Solemn Accusation, Evenly Matched, Droll & Lock Bird, and several fusion-based negates give the deck breadth on both turns. Structural weaknesses drag the score down: the Light and Darkness Ritual engine has only 12 exact-name copies (16.9 percent purity) and competes with the Shaddoll Fusion engine for slots, and the deck has no Side Deck. The score was built from consistency, median output, and interaction measured on the system, not from averaging card scores, and the archetype's 77 percent core presence in usage statistics confirms the list is real but did not add points.

Dimension scores

How the score was computed

Strategy profile: 0.7 Midrange + 0.3 Combo (Combo ratio applied to D1/D3/D5/D7 weight emphasis; no secondary weights are altered in the final sum). Structural ≈ 61, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine split (-2); No Side Deck (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*61 + 0.20*52 = 59.2; modifiers -5 gives 54.2, rounded to 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · key two-card combo ≈ — · full-brick estimate ≈ 0.16 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Interaction breadth across both turns: three Solemn-family traps, Evenly Matched, Droll & Lock Bird, plus fusion-based negates
• Fusion boss ceiling (Meshahrail, Shekhinaga, Winda) with high ATK and negation attached
• Eleven searcher-text cards and GY recursion keep the engine re-accessible across turns

Weaknesses

• Two engines (Shaddoll Fusion and Light and Darkness Ritual) with only 12 exact-name Ritual-support copies
• No Side Deck, so there is no post-side adaptation
• Significant dead-card risk from 16 singletons and off-plan staples such as Greed and Mulcharmy

Critical choke points

• Shaddoll Fusion / El Shaddoll Fusion starter access, with only 3 copies each
• Light and Darkness Ritual (single copy) as the only ritual enabler for the 3000 ATK Ritual bosses

• Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (no tournament link)
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent One unresolved passcode (20366274, 2 copies) counted as Main Deck; its role is unknown No Side Deck: no best-of-3 adaptation data No win-rate telemetry: going-first/second and matchup signals are Inferred Meta Power is Provisional unless a dated metagame sample is supplied
