Light and Darkness Ritual Deck #772723 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ritual boards from Magician of Dark Chaos - Black Chaos and Black Luster Soldier, with Black Chaos as the repeatable Special Summon engine, backed by Synchro beaters (Crimson King, Red Dragon Archfiend, Stardust Dragon, Chaos Angel is not in the run per usage stats).; Synchro and Fusion pressure (Stardust Dragon, Ecclesia and the Dark Dragon, The Dragon that Devours the Dogma) once the ritual engine has stabilised the board.
• Turn 1 (going first): Search a Light and Darkness Ritual monster (Mind Shuffle, Ragged Records of Rites, Light and Darkness Ritual) and ritual-summon, with Ash Blossom and Droll & Lock Bird held as hand traps once the starter is live (Inferred).
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash, Ghost Ogre & Snow Rabbit, Droll, Griffoh) to break the opponent's board, then resolve a ritual or Synchro follow-up through the open field (Inferred).
• Recovery: Recover through recursion: Skull Archfiend of Chaos and Ragged Records of Rites return cards from GY and banishment, and Pot of Sloth and Pot of Prosperity refill the hand (Inferred from card text).
• After siding: No side deck is registered (side 0), so no post-side plan exists in the list as submitted; a best-of-3 plan cannot be assessed from this evidence.

Why it scores here

The deck is evaluated as a system and not as an average of its card scores. Its consistency is driven by 12 searcher-text cards (P(at least one searcher in a 5-card opening hand) is about 0.72, Inferred) and 89% opening access to the archetype core (Inferred). Its interaction is dense, with 6 hand traps, 13 negation-text cards and 23 removal-text cards, which is the main reason D7 and D5 score above the midpoint. Its ceiling is capped by the absence of any recorded boards, so D3 and D4 are inferred from card text only and D4 is kept near the midpoint. The deck has no side deck and no tournament or meta sample, so D12 and D13 are low or provisional, and the deck is Illegal (Ash Blossom at 3 copies against an OCG limit of 2), which caps the final score. Popularity from usage statistics confirms the list is real and accessible, but it did not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (over-limit Semi-Limited card) (-8). Final formula: Theoretical only (Illegal). Structural 57 blended as 0.80*57 + 0.20*50 = 55.6, minus 8 banlist modifier = 47.6, then capped to 35 because the deck is Illegal; Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · 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 interaction: 6 hand traps, 13 negation-text cards and 23 removal-text cards
• Strong closing bodies (Black Skull Dragon 3200 ATK, Black Luster Soldier 3000, Crimson King 3000, Red Dragon Archfiend 3000)
• Recursion (Skull Archfiend of Chaos, Ragged Records, Pot of Sloth/Prosperity) supports grind

Weaknesses

• Illegal as submitted: Ash Blossom at 3 copies over the OCG limit of 2
• No side deck: best-of-3 adaptation is absent
• No recorded boards, so the ceiling and median are text-only inference
• Low archetype purity (17.1% exact-name) with 58 off-archetype copies spread across 14 sub-archetypes

Critical choke points

• Ritual summons depend on a small number of Light and Darkness Ritual Spells and monsters (Black Chaos, Magician of Dark Chaos, Black Luster Soldier)
• Ash Blossom over-limit: the list must drop one copy before any playable evaluation applies

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring 3 copies against an OCG limit of 2 (Semi-Limited); Main 55 and Extra 15 are within the OCG size rules; side is 0; Extra Deck split 12 Synchro, 2 Fusion, 1 Link; Printed ATK/DEF values for key monsters (Black Skull Dragon 3200, Black Luster Soldier 3000, Magician of Dark Chaos 2800)
• Observed: Archetype core usage: Magician of Dark Chaos 95.4%, Black Luster Soldier 90.9%, Droll & Lock Bird 72.1% inclusion
• Inferred: Opening access to the searcher and archetype core from hypergeometric estimates; Interaction quality from card text (negation and removal); Going-first and going-second plans from card text
• Provisional: Meta and matchup fit (D13), since no dated sample or tournament link exists
• 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; going-first/second, matchup and brick rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied usage statistics lists S:P Little Knight as not in this deck, but the card list includes it in the Extra Deck; the discrepancy was not resolved
