Light and Darkness Ritual Deck #773164 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Magician of Dark Chaos - Black Chaos or Black Luster Soldier using Light and Darkness Ritual, then convert the 2800-3000 ATK boss into board control and attacks (structural read, not a tested line); Synchro and Fusion boss monsters from the Extra Deck (The Crimson King, Red Dragon Archfiend, Chaos Angel is not in the list) with Stardust Dragon and Ecclesia and the Dark Dragon as the Extra Deck follow-up
• Turn 1 (going first): Open on Ritual Spells and searchers (Light and Darkness Ritual, Ragged Records of Rites, Mind Shuffle) to reach a Ritual boss; hold Ash Blossom and Ghost Ogre as protection (Inferred)
• Turn 2 (going second): Use hand traps (Ash Blossom, Maxx C, Droll and Lock Bird, Ghost Ogre) to stop the opponent's first board, then rebuild through the GY with Skull Archfiend of Chaos and Black Chaos (Inferred)
• Recovery: Recover through Ragged Records of Rites, Mind Shuffle and Skull Archfiend of Chaos returning Ritual and Light and Darkness cards from the GY and banish zone (Inferred)
• After siding: None: the side deck is empty, so there is no post-side plan and any matchup change must be done in the main deck (Inferred)

Why it scores here

The score is set on the deck as a system, not from its cards or their popularity. The engine is only partly reliable: the archetype core is well represented (25 copies of the core set, P(at least one in a 5-card opening hand) about 0.96), but the two Light and Darkness Ritual spells are the only direct ritual enablers and each has about a 0.17 chance of showing up in an opening hand. The list also runs 6 hand traps and 11 negation-text cards, so interaction is strong and gives the deck its best dimension. Ceiling and median output cannot be measured because there are no recorded boards, so both are text-only inferences and the floor is scored below the ceiling on purpose. The deck is capped as Illegal: Albion the Branded Dragon is Forbidden in OCG and is run once, and the empty Side Deck leaves no post-side plan. Popularity of the archetype (core usage stats) confirms that a list like this is real and accessible, but it does not add power. The result is a theoretical, structural-only read and does not earn a normal contextual score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Control as the secondary read; weights used are the Midrange profile. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12); illegal cap (-7). Final formula: Illegal cap applied: 0.80*Structural(51) + 0.20*TournamentReliability(40) = 48.8, then modifiers (-12 banlist exposure) = 36.8, then capped to 30 because the deck is Illegal (theoretical/structural-only). Meta Power provisional/null.

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

• Archetype core is well represented (25 copies, about 96 percent opening-hand access)
• Layered interaction: 6 hand traps, 11 negation-text cards and 26 removal-text cards
• Multiple ritual and synchro boss options at 2500-3000 ATK

Weaknesses

• Illegal in OCG: Albion the Branded Dragon is Forbidden and is run at 1 copy
• Only 25 percent exact-name archetype purity and 53 off-archetype copies
• Empty Side Deck: no post-side adaptation
• Only 2 Light and Darkness Ritual spells for a deck built on that engine

Critical choke points

• Light and Darkness Ritual (2 copies) is the only direct ritual enabler and has about 0.17 chance to appear in a 5-card opening hand
• The Extra Deck fusion route depends on Albion, which is illegal, so the Fallen of Albaz route is blocked

Recommended changes

Evidence & confidence

• Verified: Legality: Albion the Branded Dragon is Forbidden and over copy limit (legal copies 0, copies run 1); Main 56 and Extra 15 are within size rules; Side is 0 cards; Copy histogram: 18 single, 10 double, 6 triple; Core usage: Magician of Dark Chaos - Black Chaos 95.2 percent, Black Luster Soldier 90.5 percent
• Observed: Exact-name purity 25.4 percent; 53 off-archetype copies; Extra Deck breakdown: 9 Synchro, 5 Fusion, 1 Link
• Inferred: Opening-hand consistency and brick estimates from hypergeometric values; Going-first and going-second plans from card text; Interaction density from text roles (11 negation-text, 26 removal-text)
• Provisional: Meta Power (null without a dated metagame sample); Matchup fit (no tournament or meta sample)
• Data gaps: no combos supplied: combo 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/starter rates) exists in YGOVN Meta Power is Provisional without a dated metagame sample Side Deck is empty, so post-side performance cannot be assessed
