Light and Darkness Ritual Deck #773676 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 45 / Extra 7 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ritual Summon a Light and Darkness Ritual boss (Black Chaos, Magician of Dark Chaos - Black Chaos, Black Luster Soldier) or Fusion/Ritual payoff to convert a 3000-ATK board into pressure; Master of Chaos / Dark Magician of Destruction Extra Deck boards that banish the opponent's monsters
• Turn 1 (going first): Search and set up the Light and Darkness Ritual engine with searchers (Shining Sarcophagus, Mind Shuffle, Light and Darkness Ritual, Ragged Records of Rites, Mulcharmy Fuwalos draw) and ritual-summon a boss; hold Ash Blossom / Ghost Belle / Ghost Ogre as interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird, Kuriboh - Multiply!) to disrupt the opponent's first board, then continue into a Ritual or Fusion boss
• Recovery: Recover through Skull Archfiend of Chaos and GY-based Ritual Spell recursion, Black Chaos placing a Continuous Trap, and searchers that refill the hand after interaction is spent
• After siding: No side deck is registered (side_count 0); no post-side plan can be evaluated from evidence

Why it scores here

The deck reliably opens a Ritual engine: its 22 searcher-text cards and 18-copy archetype core give a high chance of at least one starter in an opening hand (archetype core P(≥1 in 5) ≈ 0.93, Inferred). Its ceiling comes from the 3000-ATK ritual bosses and the Extra Deck boards (Master of Chaos, Dark Magician of Destruction), which convert advantage into pressure. Eight hand traps and multiple negation effects give layered interaction, which is why the going-second plan scores decently. The score is not earned by archetype popularity, and no card scores were averaged; the score comes from the deck as a system. It is capped low because the list is illegal: Ash Blossom & Joyous Spring is run three times against a Semi-Limited limit of two, and the deck has no side deck and no recorded boards, so the evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Combo primary with Midrange secondary, weights taken from the Combo profile. Structural ≈ 64, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-12); no_side_deck (0). Final formula: No reliable metagame: 0.80*Structural(64) + 0.20*TournamentReliability(55) = 62.2; modifier -12 gives 50; Illegal cap sets final to 40 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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

• Archetype core (Black Chaos, Ash Blossom, Mulcharmy Fuwalos) is near-complete at 3 copies each, so the engine is reliably accessible
• Eight hand traps and multiple negation effects give layered interaction
• Three 3000-ATK ritual bosses and Extra Deck boards provide closing power

Weaknesses

• The list is illegal: Ash Blossom & Joyous Spring is over its Semi-Limited limit
• Low exact archetype purity (21.2%) with off-archetype Dark Magician, Kuriboh and Mulcharmy copies
• No side deck registered, so post-side adaptability cannot be assessed

Critical choke points

• Light and Darkness Ritual and the Ritual Spell chain: the engine depends on a small number of ritual spells and tributes
• Ash Blossom over the copy limit: removing the third copy is required before the list can be considered legal

Recommended changes

Evidence & confidence

• Verified: Main 45, Extra 7, Side 0; main within the 40–60 size rule, extra within 0–15; Ash Blossom & Joyous Spring run 3 copies against a Semi-Limited limit of 2 (over limit); Archetype core 18 copies; exact archetype purity 21.2%
• Inferred: Archetype core P(≥1 in opening 5) ≈ 0.93; Hand-trap P(≥1 in opening 6, going second) ≈ 0.71; Interaction density and boss-board ceiling read from card text
• Provisional: Meta Power is null; no dated metagame sample; Matchup and format fit cannot be assessed
• 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 side deck supplied — post-side adaptability cannot be scored no win-rate telemetry exists in YGOVN — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
