Light and Darkness Ritual Deck #770546 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Black Luster Soldier / Magician of Dark Chaos and attack, supported by Synchro and Fusion boss monsters from the Extra Deck; Synchro and Fusion boss monsters (Chaos Angel, Ecclesia and the Dark Dragon, The Dragon that Devours the Dogma) once their materials are available
• Turn 1 (going first): Open a Ritual or Clown Crew starter (21 archetype-core copies, about 0.92 probability of at least one in a 5-card hand), set up a hand-trap wall, then extend with Mulcharmy draw effects and Clown Crew Rehearsal or Mind Shuffle searches
• Turn 2 (going second): Use the six-card hand to hold Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit and Evenly Matched to slow the opponent, then convert the ritual engine into a board the opponent cannot easily clear
• Recovery: Recover through Ragged Records of Rites, Mind Shuffle, Clown Crew Finale and Mulcharmy draw effects that refill the hand, plus Skull Archfiend of Chaos and Light and Darkness Ritual from the GY
• After siding: No side deck is listed, so there is no post-side plan; the deck must rely on the main deck alone and cannot be adjusted between games

Why it scores here

The deck reliably opens a functional Light and Darkness Ritual or Clown Crew starter, since the archetype-core group has about 0.92 probability of at least one copy in a 5-card hand. It converts that opening into board presence through ritual bosses and Synchro/Fusion extenders, and it has real interaction density from eight hand traps plus Evenly Matched, Dragon's Mind and Lightning Storm. Its ceiling and median output are not measured because no combos were supplied, so those are inferred from card text only. The score is capped by the copy-limit violation (three Ash Blossom & Joyous Spring against a limit of two), which makes the list illegal; this is a theoretical, structural-only read. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: illegal copy-limit violation (-12). Final formula: Theoretical only (illegal list): 0.80*Structural(52) + 0.20*TournamentReliability(45) = 51, then -12 illegal copy-limit modifier = 39; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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 group is very likely to open (about 0.92 for at least one copy in a 5-card hand)
• Eight hand traps plus Evenly Matched, Dragon's Mind and Lightning Storm give strong interaction density
• Multiple Extra Deck boss options (Chaos Angel, Ecclesia and the Dark Dragon, Enigmaster Packbit)

Weaknesses

• Illegal: Ash Blossom & Joyous Spring run 3 times against a limit of 2
• Low archetype purity (17.1%) spreads the deck across Clown Crew, Mulcharmy, Light and Darkness Ritual and many singletons
• No Side Deck, so the deck cannot adjust between games
• No recorded combos, so the ceiling and median cannot be measured

Critical choke points

• Ash Blossom & Joyous Spring copy count: the list must drop one copy before it is legal
• Ritual summon of Black Chaos or Black Luster Soldier depends on Light and Darkness Ritual or matching Ritual Monsters in hand or GY

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within TCG size rules (main 40–60, extra 0–15); Ash Blossom & Joyous Spring: 3 copies vs legal limit 2 (Semi-Limited); Archetype purity 17.1% (12 exact-name of 70 copies); Droll & Lock Bird Limited at 1 copy (legal); Extra Deck composition: 8 Synchro, 3 Fusion, 2 Xyz, 2 Link
• Inferred: P(at least one archetype-core card in a 5-card hand) ≈ 0.92; Going-first and going-second plans from card text; Consistency and brick estimates from copy histogram; Interaction density from role tags and card text
• Provisional: Meta Power (no dated metagame sample); Format fit (D13) and matchup coverage (no tournament link)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck present, so post-side performance cannot be assessed
