Light and Darkness Ritual Deck #772794 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual or Fusion summon a 3000-ATK Light and Darkness Ritual boss (Black Chaos, Black Luster Soldier, Magician of Dark Chaos) and protect it with hand traps and Spell/Trap negation; Link and Synchro pressure from the Extra Deck (Fancy Ball, Masquerena, Underworld Goddess) if the ritual line is stopped
• Turn 1 (going first): Open a ritual starter plus Light and Darkness Ritual or Magicians search, convert through Ragged Records or Mind Shuffle into a 3000-ATK ritual boss, and hold Ash Blossom, Ghost Ogre or Solemn for the first interaction
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird (1 copy), Ghost Ogre and Nibiru as hand traps to break the opponent's opener, then rebuild a ritual board from the GY
• Recovery: Skull Archfiend of Chaos and Mulcharmy Fuwalos recur from hand or GY and Pot of Sloth refills; recovery depends on the Light and Darkness Ritual searchers
• After siding: Not evaluable: the deck runs no side deck (Side Deck size 0)

Why it scores here

The deck's score comes from the system: an 18-copy archetype core gives about an 84% chance of at least one core card in a 5-card opening hand (Inferred), and a ritual boss plus Ghost Ogre, Ash Blossom and Solemn gives real going-first and going-second interaction. The ceiling is a 3000-ATK Ritual boss backed by the GY recursion and Mind Shuffle line, but the median is capped by single-copy ritual starters and by an off-archetype split across Dark Magician, Prophecy, Greed and Dominus cards (exact archetype purity 16%). Illegal copy counts on Ash Blossom and Dominus Impulse and an empty side deck cap the final score, and no combo boards, tournament results or win rates exist in the evidence. Popularity was not credited: the archetype-stat core and the 84% core-presence figure confirm the list is real and accessible, not that it is strong, and the score was not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54, Going First ≈ 56, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-2); no recorded combos or tournament data (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal deck capped low by the legality rule; structural-only read

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.84 · 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

• Archetype core is redundant (84% chance of at least one core card in a 5-card opening hand)
• Layered interaction: Ash Blossom, Ghost Ogre, Solemn, Dominus Impulse, Spell Shattering Sword, Magician's Combination
• Multiple 3000-ATK ritual bosses and recursion via Skull Archfiend and Mulcharmy

Weaknesses

• Illegal copy counts on Ash Blossom and Dominus Impulse
• Off-archetype split (16% exact purity) weakens engine coherence
• Single-copy ritual starters and Extra Deck flex slots (Masquerena, Relinquished Anima)
• No side deck

Critical choke points

• Light and Darkness Ritual searcher and ritual starter (1 copy each for the key bosses)
• Hand traps are the only early interaction; a full brick of spells and no hand trap fails going second

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring and Dominus Impulse at 3 copies vs 2 legal in OCG; Main 60, Extra 15, Side 0 within OCG size rules; Core presence 84.6% of archetype core cards (usage statistics)
• Inferred: Consistency: P(at least one archetype core card in 5-card hand) about 0.84; Hand-trap coverage on the going-second side about 0.68; Negation and removal coverage from card text (Ash, Ghost Ogre, Solemn, Dominus Impulse, Spell Shattering Sword); Ritual boss conversion ceiling from text (Black Chaos, Magician of Dark Chaos, Black Luster Soldier)
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link); Tournament reliability (no win-rate telemetry)
• 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 no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is provisional unless a dated metagame sample is supplied deck title is null; the archetype is taken from the deck record
