Evil Twin Deck #759102 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Evil Twin Link monsters (Evil Twin Ki-sikil, Evil Twin Lil-la, Unchained Soul Lord of Yama) and Fiendsmith Fusion/Link pressure built from the Live Twin and Spright starter chain; Fiendsmith's Lacrima and Fiendsmith's Desirae from Fiendsmith's Tract and Lacrima the Crimson Tears
• Turn 1 (going first): Open Live Twin Ki-sikil or Lil-la (P at least one in hand of 5 about 0.34 each), summon Spright or Live Twin starter, recover with Secret Password or Spright Jet, then link into Evil Twin Link monsters
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Maxx C, Spright Red and Spright Carrot to answer the opponent's first summon or activation, then convert the surviving board through Live Twin and Spright engine chains
• Recovery: Spright Blue and Spright Jet recover a Spright or Live Twin monster from the Deck, and Fiendsmith's Engraver and Lacrima the Crimson Tears recover Fiendsmith material from the Graveyard
• After siding: No sideboard is registered, so there is no post-side plan; the deck cannot adapt between games

Why it scores here

The deck has a real Evil Twin starter engine: the core archetype group gives about a 0.98 chance of at least one core card in a going-first opening hand, and Live Twin Ki-sikil and Lil-la each carry roughly a 0.34 chance of appearing in that hand. Interaction is the strongest system trait, with 11 negation-text cards and 6 hand traps, which earns credit for going-second disruption. Conversion is only text-inferred because no recorded boards exist, so the ceiling and median sit close together at moderate values. The deck is capped low because it runs three Forbidden cards (Triple Tactics Talent, Knightmare Gryphon, D/D/D Wave High King Caesar) and has no side deck, so it is scored as theoretical/structural only. Archetype popularity did not add points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 50, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*50 + 0.20*40 - 12 = 36; Illegal deck capped at 30 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 negation and hand-trap package (11 negation-text cards, 6 hand traps)
• High archetype core density, so the engine is usually reachable
• Spright and Live Twin recursion gives repeatable access to starters

Weaknesses

• Three Forbidden cards make the list illegal in OCG
• No side deck, so no adaptation between games
• No recorded boards, so the combo ceiling and median are unmeasured
• Low archetype purity: many sub-archetypes compete for the same slots

Critical choke points

• Live Twin Ki-sikil and Lil-la starter access
• Single-copy Fiendsmith and Link engine pieces (Fiendsmith's Lacrima, Fiendsmith's Tract)

Recommended changes

Evidence & confidence

• Verified: Three Forbidden cards are in the Main/Extra Deck (legality check); Main Deck 40 and Extra Deck 15 are within size rules; Side deck is empty; Copy-limit usage stats: Live Twin Ki-sikil, Lil-la and Sunny's Snitch are core at 3 copies
• Inferred: Starter access and brick rate from hypergeometric draw odds; Interaction density from negation and hand-trap text flags; Going-second strength from hand-trap probability
• Provisional: Meta Power and format fit: no dated metagame sample or tournament data
• 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 win-rate telemetry for going-first/second, matchup, brick or OTK rates Meta Power is Provisional unless a dated metagame sample is supplied deck title is null side deck is empty
