Light and Darkness Ritual Deck #773066 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon a 3000-ATK Light and Darkness Ritual monster (Black Luster Soldier or Black Chaos line) and protect it with hand traps and Spell/Trap negation.; Fusion/Link follow-up (Master of Chaos, Magistus Chorozo, Azamina boards) once the Ritual board is established.
• Turn 1 (going first): Search or draw Light and Darkness Ritual, Ritual the 3000-ATK monster by tributing or banishing from GY, and keep Ash Blossom, Droll and Nibiru up as interaction.
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Nibiru, Evenly Matched and Forbidden Droplet to stop the opponent's first summon and build from a six-card hand.
• Recovery: Use Mulcharmy draw effects, Ragged Records of Rites and Skull Archfiend recursion from GY and banishment to rebuild the Ritual engine.
• After siding: No Side Deck is registered, so no post-side plan can be evaluated; the deck is theoretical only as submitted.

Why it scores here

The deck reliably opens a functional plan only through its archetype core: 23 archetype-core copies give P(at least one in a 5-card opening hand) ≈ 0.94, but each single-copy Ritual enabler (Light and Darkness Ritual, Mind Shuffle-style searchers aside) is live in only ≈ 9–11% of opening hands, so the Ritual engine's bottleneck is the single copy rather than the archetype count. Conversion is structural only: there are no recorded boards, so the 3000-ATK Ritual monsters, Master of Chaos and the Azamina Fusion line are scored as ceiling options, and the median output is scored lower because the deck depends on a sequence of Ritual, Fusion and Link steps. Interaction is the strongest part of the system: 13 hand traps and 11 negation-text cards (Ash Blossom, Droll & Lock Bird, Nibiru, Evenly Matched, Forbidden Droplet, Spell Shattering Sword) give a going-second P(≥1 hand trap in six cards) ≈ 0.82. The score is capped low because the list is illegal: Ash Blossom is run at 3 copies against a Semi-Limited limit of 2, and WANTED is run at 2 copies against a Limited limit of 1. The Structural score (≈ 49) is therefore a theoretical read only, not a legal Final Contextual score, and the deck has no Side Deck. Popularity was not credited: archetype core usage (≈ 95% for Black Chaos Magician) confirms the list is real but earned no points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary; Midrange weights used for Structural (Structural ≈ 49 before the illegal cap). Structural ≈ 49, Going First ≈ 46, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); no Side Deck (-2); illegal_cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*49 + 0.20*35 - 10 ≈ 36, then capped to 30 because the deck is Illegal (copy-limit violations); theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 hand-trap and negation package (13 hand traps, 11 negation-text cards) gives strong going-second interaction
• Archetype core is present in almost every opening (≈ 0.94 for ≥1 of 23 copies)
• Multiple 3000-ATK Ritual and Fusion finishers, plus Mulcharmy and Ragged Records draw and recovery

Weaknesses

• Illegal list: copy limits are exceeded for Ash Blossom and WANTED
• Single-copy Ritual enabler (Light and Darkness Ritual) is rarely in the opening hand
• No Side Deck and no post-side plan
• No combo or tournament data; ceiling and median are text-only inference

Critical choke points

• Light and Darkness Ritual (1 copy): if absent, the 3000-ATK Ritual monsters cannot be summoned
• Ash Blossom at 3 copies: the illegal over-limit copy is also the deck's main hand-trap redundancy

Recommended changes

Evidence & confidence

• Verified: Main 55 / Extra 15 / Side 0 size is within the OCG range (40–60 / 0–15 / 0–15); Ash Blossom 3 copies vs Semi-Limited legal 2; WANTED 2 copies vs Limited legal 1 (two over-limit violations); Droll & Lock Bird and S:P Little Knight are at their Limited cap of 1; Hypergeometric draw odds from the resolved Main Deck (0.2529 for 3 copies in 5 cards; 0.0909 for 1 copy); Archetype-core usage ≈ 95% for Magician of Dark Chaos - Black Chaos and ≈ 90% for Black Luster Soldier
• Observed: Usage statistics show the deck runs 12 of 14 archetype-standard core cards (85.7%); S:P Little Knight and Chaos Angel are absent
• Inferred: Ritual engine reliability and single-copy Light and Darkness Ritual bottleneck (≈ 9% in opening 5); Hand-trap coverage on going second (P ≈ 0.82) and interaction density; Ceiling and median output of the Ritual and Fusion lines from card text only; Going-first and going-second power components
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (no tournament link); D12 side-deck adaptability (no Side Deck)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered (Side Deck size 0) Deck title is null; deck name not available
