Light and Darkness Ritual Deck #773030 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±12 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Ritual, Synchro
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro beatdown from Red Dragon Archfiend and other 3000+ ATK Synchro monsters, with Black Chaos and Black Luster Soldier as the Ritual boss line; Ritual Summon Magician of Dark Chaos - Black Chaos or Black Luster Soldier via Light and Darkness Ritual, then close with the Synchro extra pool
• Turn 1 (going first): Open a Resonator Tuner or Crimson Gaia to reach Red Dragon Archfiend, then Synchro Summon with Resonator material and protect the board with Ash Blossom, Evenly Matched or Dominus Impulse
• Turn 2 (going second): Use the hand-trap suite (Ash, Droll & Lock Bird, Nibiru, Solemn Judgment, Mulcharmy Fuwalos) to break the opponent's first summon chain, then rebuild through Resonator and Synchro lines
• Recovery: Bone Archfiend and Skull Archfiend of Chaos recycle the GY, and Mind Shuffle, Griffoh and Crimson Call refill the hand with ritual or Red Dragon Archfiend routes
• After siding: No side deck is registered, so the post-side plan is absent; the deck cannot adapt between games as built

Why it scores here

The deck reliably reaches its Resonator and Crimson Gaia access points, so the Synchro engine is live in most openings, but the Ritual half depends on a single Light and Darkness Ritual spell and is much less consistent. Its interaction suite is the strongest part of the system: nine hand traps, eleven negation texts and 27 removal texts give it layered answers on both turns. Its closing power comes from several 3000+ ATK Synchro monsters, with Red Dragon Archfiend and Hot Red Dragon Archfiend Abyss as the main finishers. The score is capped at 25 because the list is illegal: Ash Blossom and Dominus Impulse are each run three times against a two-copy OCG limit. The structural score of about 59 was computed from the system's consistency, interaction and closing profile, not by averaging card scores, and the popularity of the Light and Darkness Ritual archetype did not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (-3); Hard-garnet and single-spell burden (-2); No side deck (-2). Final formula: Illegal cap applied: uncapped 0.80*59 + 0.20*48 = 56.8 (Meta provisional), then capped to 25 because the list violates copy limits; structural-only read

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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

• Layered interaction: nine hand traps plus negation and removal spells on both turns
• Multiple 3000+ ATK Synchro finishers with direct-attack and board-breaking text
• Synchro extra pool is wide enough that Resonator material shows up often

Weaknesses

• Ritual half relies on one Light and Darkness Ritual spell
• Copy-limit violations on Ash Blossom and Dominus Impulse make the list illegal as built
• No side deck, so there is no post-side adaptation
• Low exact archetype purity dilutes engine coherence

Critical choke points

• Light and Darkness Ritual (single copy) gates the whole Ritual line
• Resonator Tuner access is required for most Synchro starts

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: Ash Blossom and Dominus Impulse each run 3 copies against a 2-copy OCG limit; Main 55 and Extra 15 are within OCG size rules; Nine hand traps, 11 negation texts and 27 removal texts from card text; Exact archetype purity 11.4%
• Observed: Archetype usage stats: Light and Darkness Ritual core cards show 90-95% inclusion (Black Luster Soldier, Magician of Dark Chaos)
• Inferred: Starter probabilities from hypergeometric estimates (archetype core 0.81; ritual spell 0.09 in opening 5); Going-second hand-trap coverage P(>=1 in opening 6) 0.68; Structural scores across the 14 dimensions
• Provisional: Meta Power null and D13 neutral 50, since no dated metagame sample exists; Tournament reliability is estimated from structural dimensions only
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power is Provisional unless a dated metagame sample is supplied No side deck supplied
