Light and Darkness Ritual Deck #772703 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ritual-summon Black Chaos or Black Luster Soldier, then convert board presence into Fusion and Synchro pressure; Fallen of Albaz and Dogmatika/Branded fusion lines via Albion-style and Mirrorjade-style extra-deck summons
• Turn 1 (going first): Search the Ritual Spell or a starter (Ragged Records, Mind Shuffle, Skull Archfiend), then Ritual Summon Black Chaos or Black Luster Soldier with Light and Darkness Ritual
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Droll, and Nibiru as hand traps to break the opponent's first line, then continue into the Ritual or Fusion follow-up
• Recovery: Recycle Skull Archfiend and Mind Shuffle from GY and banish to re-enable Ritual or Fusion lines after an interruption
• After siding: No side deck is registered, so no post-side plan can be read from this list

Why it scores here

The deck is illegal in its declared OCG format: three copies of Ash Blossom, two copies each of Branded in High Spirits and Droll & Lock Bird, and one copy of the Forbidden Albion the Branded Dragon all exceed their legal limits, so the rubric's illegal-list cap applies and this is a theoretical, structural-only read. Structurally, the Ritual core (Light and Darkness Ritual with Black Chaos and Black Luster Soldier) is reasonably accessible, with an archetype-core group probability of about 0.93 for at least one card in the opening five and about 0.87 for at least one searcher. Its hand-trap density (11 hand traps, about 0.75 chance of one going second) and dual Ritual and Fusion/Synchro lines give it resilience to single interruptions. The score is not an average of card scores and does not reward popularity: archetype usage stats were used only to confirm the core is present. The score is held down by the absence of any recorded combos, so the ceiling, median and going-second conversion are text-only inferences, and by the lack of any side deck.

Dimension scores

How the score was computed

Strategy profile: Combo 0.7 / Midrange 0.3. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Illegal list cap (-24). Final formula: Illegal list: 0.80*Structural(55) + 0.20*TournamentReliability(50) = 54, then -24 illegal-list cap = 30 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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 hand-trap and negation text (11 hand traps, 5 negation-text cards)
• Ritual core (Black Chaos, Black Luster Soldier) with 3000 ATK payoffs
• Redundant starters across searcher text (18 cards)

Weaknesses

• Illegal copy counts (Ash Blossom x3, Branded in High Spirits x2, Droll x2) and a Forbidden Albion in the Extra Deck
• No recorded combos, so ceiling and median are unmeasured
• No side deck registered
• Main Deck is 56 cards, about 4 over the ideal size

Critical choke points

• Ritual Summon needs Light and Darkness Ritual plus enough GY and hand material, so a single Ritual Spell or enabler removal can end the line
• Albion is Forbidden in OCG, so the Branded fusion line is unplayable as listed

Recommended changes

Evidence & confidence

• Verified: Legality violations: Ash x3 vs 2, Branded in High Spirits x2 vs 1, Droll x2 vs 1, Albion x1 vs 0 (Forbidden); Main 56 / Extra 15 / Side 0 counts; Archetype-core probability 0.9272 and searcher-group probability 0.8686 from the evidence pack
• Observed: Usage stats: Black Chaos and Black Luster Soldier appear in 67 percent and 91 percent of the archetype's lists
• Inferred: Ritual and Fusion engine conversion; Hand-trap and negation effectiveness; Brick and consistency estimates
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit
• 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 side deck registered: post-side adaptability cannot be scored No win-rate telemetry for this deck Meta Power is provisional without a dated metagame sample
