Light and Darkness Ritual Deck #773150 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±6 · Confidence: Medium)

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

Legality

Main 57 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual Summon a Level 8 boss (Magician of Dark Chaos - Black Chaos, Black Luster Soldier - Soldier of Light and Darkness) or Dark Magician of Chaos / Black Skull Dragon using Light and Darkness Ritual, then close with Link and Synchro beaters (Underworld Goddess, Chaos Angel).; Dark Magician / Shining Sarcophagus value engine that searches and recurs Dark Magician-named pieces for repeated Fusion, Ritual and Special Summon pressure.
• Turn 1 (going first): Open with Light and Darkness Ritual or a searcher (Mind Shuffle, Ragged Records of Rites, Dark Magical Circle is absent; Shining Sarcophagus and Mind Shuffle reach the Ritual pieces), then Ritual Summon a boss on turn 1-2 while holding Ash Blossom and Infinite Impermanence for the opponent's first interaction.
• Turn 2 (going second): Hold Ash Blossom and Infinite Impermanence and Kuriboh for the opponent's first activation, then rebuild with the searcher package. Success depends on drawing one hand trap in six cards, which is roughly one in three.
• Recovery: Recover from the GY with Ragged Records of Rites, Skull Archfiend of Chaos, Light and Darkness Ritual (GY add-back), Dark Magician of Chaos and Mind Shuffle, which is a deep recovery package.
• After siding: No Side Deck is registered, so there is no post-side plan. Best-of-3 adjustment is unavailable.

Why it scores here

The deck reliably opens a searcher-heavy engine: about 90% of hands hold at least one of the 20 searcher-text cards, and the Light and Darkness Ritual pieces are reachable through Mind Shuffle and Ragged Records of Rites. Conversion depends on Ritual Summoning one of the 1-of bosses, so the deck's ceiling is set by Black Chaos, Black Luster Soldier and Dark Magician of Chaos, while its median output is unmeasured because no recorded boards exist. Interaction is the strongest system trait: Ash Blossom and Infinite Impermanence (both x2), Kuriboh and Griffoh cover the opponent's first activation, and the GY recursion package (Ragged Records, Skull Archfiend, Dark Magician of Chaos) keeps the deck alive across turns. Popularity did not earn points: usage stats show the archetype core is real, but inclusion alone was not scored, and the 14 dimensions were scored on the system, not as an average of card scores. The deck is held back by the absence of a Side Deck, by 41 singleton main-deck slots that lower consistency, and by a going-second plan that depends on hitting one of four hand traps in six cards.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.5, Going First ≈ 62, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: no Side Deck (-3); banlist exposure (-1); engine_sprawl (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (-7); Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.17 · 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

• Dense searcher package: 20 searcher-text cards, about 90% to hit at least one in an opening hand.
• Layered interaction: 4 hand traps, 11 negation-text and 20 removal-text cards.
• Recovery is deep: Ragged Records, Skull Archfiend, Dark Magician of Chaos and Ritual GY add-back.
• Boss-level closers at 2800-3500 ATK.

Weaknesses

• No Side Deck, so zero best-of-3 adaptability.
• 41 singleton main slots lower consistency.
• Exact archetype purity is 13.9%, so engine cohesion depends on several sub-archetypes.
• No recorded combos, so floor and median are unmeasured.

Critical choke points

• Light and Darkness Ritual (2 copies) is the central starter; P(>=1 in opening 5) = 0.169.
• The Ritual boss depends on the Ritual Spell and the correct material set, so one missing piece can stop the turn.
• Going-second hand-trap coverage depends on drawing one of four hand traps in six cards (0.367).

Recommended changes

Evidence & confidence

• Verified: Legal main 57, Extra 15, Side 0 within size rules; All restricted cards within copy limits (Limited 1, Semi-Limited 2); Copy histogram: 41 singletons, 8 doubles; Card text and archetype fields from the evidence pack
• Observed: Usage statistics show the Light and Darkness Ritual core (Magician of Dark Chaos, Black Luster Soldier) is included in 90-95% of the archetype's decks
• Inferred: Ritual starter access and searcher density (hypergeometric); Brick rate and going-second hand-trap coverage; Interaction density and board-breaking read from text; Ceiling read from card text
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference. No tournament link: archetype meta share and per-pilot record are absent. No win-rate telemetry (going-first/second, matchup, brick and starter rates) exists. Meta Power is provisional unless a dated metagame sample is supplied.
