Light and Darkness Ritual Deck #765204 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon a 3000-ATK boss (Black Chaos, Black Luster Soldier, Magician of Dark Chaos - Black Chaos) through Light and Darkness Ritual, backed by Extra Deck Fusion and Link pressure; Dark Magician fusion/Link pressure (Dark Magician of Destruction, Red-Eyes Dark Dragoon) once the board is established
• Turn 1 (going first): Open with Light and Darkness Ritual or a Ritual-searching monster, convert to a Ritual boss, and hold hand traps (Ash Blossom, Droll & Lock Bird, Ghost Belle) for the opponent's first activation
• Turn 2 (going second): Use Nibiru, Droll & Lock Bird, Ash Blossom and Ghost Belle to stop the opponent's opening, then rebuild the Ritual engine from the GY with Skull Archfiend of Chaos and Mind Shuffle
• Recovery: Recover Light and Darkness Ritual, Black Chaos and Ritual monsters from the GY through Skull Archfiend of Chaos and Mind Shuffle, and restart the boss line
• After siding: No side deck is run, so there is no post-side plan; the list has no sideboard to adapt the 3000-ATK boss plan to the opponent

Why it scores here

The deck is scored as a system: the Light and Darkness Ritual core (23 copies of the archetype core group, about 92% chance of at least one in a 5-card opening hand) gives a reasonably reliable path to a 3000-ATK Ritual boss, and the 12 hand traps and Spell/Trap removal give it strong interaction density. Its ceiling comes from Black Chaos, Black Luster Soldier and Magician of Dark Chaos, while the median is held back by the Dark Magician and Prophecy support cards being off-engine (exact archetype purity is only 20%). Resilience is decent because Skull Archfiend of Chaos and Mind Shuffle recover Ritual pieces, but the empty side deck and no post-side plan cap the score. The deck is illegal in the TCG format (Ash Blossom over its Semi-Limited limit and Secret Village over its Limited limit), so the score is capped at 35 and is theoretical/structural only; popularity and archetype usage did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.6, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (copy-limit violations) (-8); Empty side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*59.6 + 0.20*48 - 12 = 45.3 (uncapped); Illegal deck capped to 35 as theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Light and Darkness Ritual core has high opening-hand access (about 92% at least one core card in a 5-card hand)
• Dense interaction: 12 hand traps plus Spell/Trap and monster removal text
• Multiple 3000-ATK ritual and fusion bosses with GY recursion via Skull Archfiend of Chaos and Mind Shuffle
• Extra Deck offers Fusion, Link and Synchro routes

Weaknesses

• Illegal under TCG banlist: Ash Blossom has 3 copies (limit 2) and Secret Village has 3 copies (limit 1)
• Low exact archetype purity (20%); many off-archetype staples dilute the engine
• Empty side deck gives no post-side adaptability
• No combo or win-rate data, so median output is unverified

Critical choke points

• Light and Darkness Ritual and its Ritual monster must both be available for the boss line
• Secret Village copies are unplayable as run and are a dead card in hand

Recommended changes

Evidence & confidence

• Verified: Illegal under the TCG ban list: Ash Blossom 3 copies vs 2 allowed; Secret Village 3 copies vs 1 allowed; Main 60 and Extra 15 are within size rules; side deck is 0; Card text and banlist status for each listed card
• Inferred: Opening-hand access estimates (about 92% core, 86% searcher, 75% hand trap); Ritual boss ceiling from card text; Interaction density and resilience estimates from text roles
• Provisional: Meta Power and tournament reliability (no dated metagame or tournament link); Matchup coverage (D13)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchups or brick rate Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
