Light and Darkness Ritual Deck #770186 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Extra Deck and main-deck Level 10 Sacred Beast bosses (The Chaotic Phantasmal Sacred Beasts 5000 ATK, Calamity of the Sacred Beasts - Hamon, Infinity of the Sacred Beasts - Raviel) reached through Phantasm special-summon chains, with Luce the Dusk's Dark and Fiendsmith's Desirae as secondary boss options (Inferred from card text).; Fiendsmith Lacrima and Fiendsmith's Desirae lines that lower opponent ATK and negate effects after Fiendsmith Engraver searches (Inferred from card text).
• Turn 1 (going first): Search with Sacred Beasts Released, Fiendsmith's Tract and Mutiny in the Sky toward a Level 10 Sacred Beast, Special Summon it through a Phantasm effect, and keep Ash Blossom, Effect Veiler or Ghost Belle back as hand traps (Inferred).
• Turn 2 (going second): Hold hand traps (16 in the main deck, P(at least one in six-card hand) approx 0.88) to negate or destroy the opponent's first board, then rebuild through the 24 searcher-text cards and the Level 10 boss chain (Inferred).
• Recovery: Recur from the GY with Martyr of the Sacred Beasts, Sacred Beasts Released (GY banish effect), Fallen Paradise of the Sacred Beasts and Summoner of the Sacred Beasts discard-to-summon effects (Inferred from card text).
• After siding: No side deck is present (Side Deck size 0), so no post-side plan can be evaluated; D12 is scored as a gap.

Why it scores here

This list is Illegal: it runs four Forbidden cards and exceeds the copy limits of three Limited or Semi-Limited cards, so the score is a structural, theoretical read capped at 35 and is not a normal contextual score. The structural read (about 56) reflects a real engine: 24 searcher-text cards and about 0.94 probability of at least one searcher in a five-card opening hand give reasonable access to a Sacred Beast Level 10 chain. Interaction is the strongest area: 16 hand traps and 22 negation-text cards give high going-second board-breaking (D8) and end-board interaction (D7). Consistency is held back by hand-trap dead-draws, no side deck (D12 = 20), an Extra Deck that is 3 of 15 illegal, and no recorded combos, so floor and median output (D4) are Provisional. The score comes from consistency, interaction and boss power on the system; it was not averaged from card scores and was not raised by the Phantasm and Fiendsmith archetypes' popularity, which had no usage-based credit.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); choke_point_limited_engine (-2). Final formula: Theoretical only. Unmodified formula 0.80*Structural(56) + 0.20*TournamentReliability(45) + modifiers(-10) = 44, capped at 35 because the deck is Illegal (no normal contextual score). Meta Power is null (provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 density (24 searcher-text cards; about 0.94 probability of at least one in a 5-card opening hand)
• 16 hand traps and 22 negation-text cards give strong going-second interaction
• High-ATK Level 10 Sacred Beast bosses (up to 5000 ATK) reachable through Phantasm summon chains
• Recursion from GY (Martyr, Summoner, Fallen Paradise) supports continuing after disruption

Weaknesses

• Illegal list: 4 Forbidden cards and 3 copy-limit overages (Engraver 3 vs 1, Droll 2 vs 1, Ash 3 vs 2)
• No side deck, so no best-of-3 adaptability
• Hand traps create dead draws when the opponent does not interact
• Extra Deck has 3 of 15 slots occupied by Forbidden or over-limit cards
• No recorded combo boards, so floor and median output are unknown

Critical choke points

• Fiendsmith Engraver: 3 copies run, 1 legal
• Droll & Lock Bird: 2 copies run, 1 legal
• Ash Blossom & Joyous Spring: 3 copies run, 2 legal
• Forbidden Extra Deck cards Varudras, Aerial Eater and Cross-Sheep (and Triple Tactics Talent in the main deck) cannot be legally played

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal; 4 Forbidden cards; 7 copy-limit violations; Main 57, Extra 15, Side 0 counts; Card stats and text excerpts from evidence; Archetype usage shows Phantasm/Fiendsmith cores (not scored as power)
• Inferred: Searcher access and hand-trap consistency from hypergeometric estimates; Interaction density and going-second disruption from card text; Win-condition and turn-1/turn-2 plans from card text; Recovery plan from GY recursion text
• Provisional: Floor and median combo output (no boards); Meta and matchup fit (no dated meta sample); Post-side strength (no side deck)
• Data gaps: Deck is Illegal: contextual score not normal; theoretical structural read only 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; post-side plan and D12 scoring are gaps No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied
