Light and Darkness Ritual Deck #766728 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Black Luster Soldier / Magician of Dark Chaos - Black Chaos with Light and Darkness Ritual, then close with 3000-ATK boss monsters and Fusion/Synchro follow-ups (theoretical; no combo data); Fusion/Synchro Extra Deck pressure (Mirrorjade, The Dragon that Devours the Dogma, Chaos Angel) enabled by Fallen of Albaz and Ecclesia-line starters
• Turn 1 (going first): Open a Light and Darkness Ritual or Fallen of Albaz starter, use Ash Blossom / Griffoh / Droll to protect the first engine card, then ritual or fuse into a 3000-ATK boss
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Nibiru) to interrupt the opponent's board, then convert from the remaining hand; the 6-card hand has a 0.73 chance of holding a hand trap
• Recovery: Recover through Ragged Records of Rites, Pre-Preparation of Rites, Skull Archfiend of Chaos recursion from GY, and Mind Shuffle to refill the ritual line
• After siding: Not evaluable: the deck has an empty Side Deck, so no post-side plan exists in the export

Why it scores here

The deck reliably opens a starter: the archetype core (24 copies) has a 0.935 chance of at least one copy in a 5-card opening hand, and searchers cover most hands (0.83). Interaction is dense, with about 11 hand traps and about 8 negation effects, which earns the going-second and interaction dimensions. Conversion is the weak point: there are no recorded boards, so the ceiling and median are text-only inferences and score low. Scores come from consistency and interaction on the whole 74-card system, not from averaging card scores and not from the popularity of the archetype. The deck is Illegal (five copy-limit or Forbidden violations, including Albion the Branded Dragon at 1 copy with a limit of 0), so the normal Final formula is capped as structural-only at 25; the uncapped formula would give about 39 before the modifiers. The Main Deck is 59 cards and the Extra Deck is 15, both within size rules.

Dimension scores

How the score was computed

Strategy profile: Midrange 100%; Combo not blended because no combo evidence supports it. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-8); No side deck (-4). Final formula: Illegal cap: uncapped 0.80*52 + 0.20*45 + modifiers(-12) ≈ 39, capped to 25 as structural-only theoretical evaluation

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (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 (11 hand traps, 8 negation texts)
• High starter density: 0.94 chance of an archetype-core card in opening 5
• Several 3000-ATK boss monsters across Ritual and Fusion lines
• Good recursion through Skull Archfiend and Ragged Records of Rites

Weaknesses

• Illegal list: five copy-limit or Forbidden violations, including a Forbidden card
• No side deck, so no post-side plan
• Low archetype purity (18.9%) and many off-archetype sub-archetype cards
• No recorded combos to confirm conversion

Critical choke points

• Light and Darkness Ritual (1 copy) and Pre-Preparation (1 copy) are single points for the ritual line
• Ash Blossom and Droll are the main hand-trap answers; if the legal limits drop them to fewer copies, going-second protection falls

Recommended changes

Evidence & confidence

• Verified: Illegal status and five copy-limit or Forbidden violations (legality block); Main 59 / Extra 15 / Side 0 counts; Archetype purity 18.9% and spread; Banlist statuses of restricted cards
• Inferred: Starter probabilities 0.935 (core) and 0.83 (searchers) from hypergeometric draws; Brick proxy 0.065; Hand-trap coverage 0.73 on the going-second 6-card hand; Interaction and resilience reads from card text
• Provisional: Meta Power (no dated sample); Matchup and format fit (no tournament link)
• 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, and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck in export, so no post-side evaluation No guides attached (guides_evidence total 0)
