Evil Twin Deck #769666 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 49 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Evil Twin link beatdown: Evil Twins Trouble Sunny (3300 ATK) and Fiendsmith's Desirae (2800 ATK) or A Bao A Qu (2800 ATK) closing through a Live Twin / Ki-sikil / Lil-la board; Unchained and Fiendsmith recursion value through Unchained Soul Lord of Yama and Fiendsmith's Lacrima
• Turn 1 (going first): Open Live Twin Ki-sikil / Lil-la / Sunny's Snitch to build a Ki-sikil plus Lil-la board, Secret Password or the Snitch for an Evil Twin, then Link into an Evil Twin Link monster (Inferred from card text; no combo samples)
• Turn 2 (going second): Keep a 6-card hand with 2+ hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Infinite Impermanence) to stop the opponent's first summon or search, then rebuild through Evil Twin link summons (Inferred)
• Recovery: Ki-sikil Frost and Lil-la Sweet recursion from the GY, Unchained Soul Lord of Yama revival, and Live Twin searchers (Inferred from card text)
• After siding: Not supported: side deck is empty, so there is no post-side plan (verified from the list)

Why it scores here

This list is Illegal in OCG because it runs Knightmare Gryphon and D/D/D Wave High King Caesar, both Forbidden, so it gets no normal Final score and is capped to a structural-only read of 30. Structurally the deck has a plausible engine: three Live Twin Ki-sikil, three Sunny's Snitch and Secret Password give a probability of about 0.28 for at least one three-copy starter in a 5-card opening hand, and the Evil Twin link line can reach 3300 ATK. Interaction is the strongest part of the system, with 12 hand traps, 13 negation-text cards and 16 removal-text cards, which makes it hard to go first into and strong to go second. Consistency and brick management are weaker: 14 singleton slots, 64 off-archetype copies across several sub-archetypes, and no side deck. No recorded combos, tournament results or win-rate telemetry exist, so the median and matchup scores are Inferred or Provisional, and the score comes from the structure of the list, not from Evil Twin's popularity or an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53, Going First ≈ 42, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Illegal list: no normal Final. Theoretical 0.80*53 + 0.20*45 = 51.4; banlist modifier -12 gives 39.4; capped to 30 (structural-only, illegal). Meta provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.28 · 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 hand-trap and negation suite (12 hand traps, 13 negation-text cards)
• Strong going-second interaction (P = 0.83 of at least one hand trap in 6 cards)
• High-ATK link finishers (Sunny 3300, Desirae 2800, A Bao A Qu 2800)

Weaknesses

• Illegal in OCG: two Forbidden cards in the list
• No side deck, so no post-side adaptation
• Low archetype purity: 64 off-archetype copies across 17 sub-archetype names
• Limited starter density for three-copy engine cards

Critical choke points

• Live Twin Ki-sikil / Lil-la starter access in the opening 5 (about 0.28 per 3-copy card)
• Evil Twin link summon requires a specific Ki-sikil/Lil-la board; a single negated link breaks the line

Recommended changes

Evidence & confidence

• Verified: Illegal status: Knightmare Gryphon and D/D/D Wave High King Caesar are Forbidden in OCG and run at 1 copy each; Main 49 and Extra 15 are within OCG size limits; Side is 0 (within 0-15); Usage stat: Live Twin Ki-sikil and Sunny's Snitch are in 70.6% of sampled lists; Fiendsmith's Sequence and Requiem in 70.6%, not run here
• Inferred: Starter probability 0.28 for each three-copy starter; searcher probability 0.55; Going-second hand-trap probability 0.83; Link ceiling and combo lines from card text
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no 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 (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Illegal list: structural-only evaluation, no normal Final Contextual score
