Light and Darkness Ritual Deck #770567 — 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 60 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos, Ruler of the End of the World or Mitsurugi ritual monsters to convert the Ritual Spell and GY resources into a large board; Link and Fusion finishers from the Azamina and Dark Magician sub-engines
• Turn 1 (going first): Search a Ritual Spell (Pre-Preparation, Ragged Records, Mind Shuffle) and ritual-summon a Black Chaos or Ruler using Light and Darkness Ritual, with Ash Blossom and Droll as the only interaction
• Turn 2 (going second): Rely on Ash Blossom and Droll & Lock Bird to stop the opponent's first search, then Ritual Summon from the GY with Skull Archfiend and Griffoh as recovery
• Recovery: Skull Archfiend of Chaos and Ragged Records of Rites recycle ritual spells from the GY, and Mind Shuffle recovers a ritual monster from the Deck
• After siding: Not evaluable: the deck runs no side deck, so there is no post-side plan

Why it scores here

The deck is scored as a system: 16 core archetype copies give about an 80 percent chance of at least one in a 5-card opening hand (Inferred), and 28 searcher-text cards make a starter reachable in almost every hand. Its ritual engine converts GY and banished resources into large monsters, and the Ash Blossom, Droll and Nibiru package gives it several interruption options. Popularity and usage-statistic overlap do not earn points, and card scores were not averaged into the result. Structural strength is capped by weak archetype purity (17 percent exact-name, 63 off-archetype copies), no recorded combos (combo dimensions are text-only inference), and an empty side deck. The deck is illegal as built (three copy-limit violations and an Extra Deck of 16), so the final score is capped at 25 and the result is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Balanced (default; strategy is mixed between Midrange and Combo). Structural ≈ 51, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist and copy-limit exposure (-5); Extra Deck over size (-3); No side deck (0); Illegal legality cap (0). Final formula: Illegal deck: Structural 51 -> 0.80*51 + 0.20*45 = 50 before modifiers; modifiers -8 gives 42; legality cap sets final score to 25. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · key two-card combo ≈ — · full-brick estimate ≈ 0.2 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core archetype group of 16 copies gives about an 80 percent chance of a starter in the opening 5 cards (Inferred)
• 28 searcher-text cards and 12 negation-text cards give multiple routes and interaction (Inferred from text)
• Ash Blossom, Droll and Nibiru cover hand-trap and floodgate-style disruption (Verified text)

Weaknesses

• Illegal as built: three copy-limit violations and an Extra Deck of 16 (Verified)
• Archetype purity 17 percent, with 63 off-archetype copies spread across Mitsurugi, Sinful Spoils, Azamina, Dark Magician, Diabellstar and others (Verified composition)
• Empty side deck, so no post-side plan (Verified)
• No recorded combos or win-rate data (Verified gap)

Critical choke points

• Black Chaos and Light and Darkness Ritual are the main engine pieces; losing them to one interruption leaves few alternate ritual routes (Inferred)
• Ash Blossom at 3 copies is over its legal limit of 2, so the deck cannot be played as listed (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality: three copy-limit violations and Extra Deck of 16 (above TCG maximum of 15); Card text and banlist status for each listed card; Hypergeometric draw probabilities from the main deck; Side deck count of 0
• Inferred: Opening-hand starter reliability (0.80 for the core group, 0.96 for searchers); Brick rate proxy of about 20 percent; Interaction density from negation and removal text; Ceiling of Black Chaos and ritual spells from card text
• Provisional: Meta power (null; no dated metagame sample); Matchup fit and tournament reliability (no tournament link or win-rate data)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going first/second, matchup, brick and starter rates) Meta Power is provisional unless a dated metagame sample is supplied Deck is Illegal as built, so the score is theoretical and structural only
