Evil Twin Deck #758700 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Link-based board pressure from Evil Twin Link monsters and Evil Twins Ki-sikil & Lil-la (not evaluable as a legal list until the two Forbidden cards and the Extra Deck overflow are removed); Fiendsmith Lacrima and Desirae fusion pressure, plus Super Starslayer TY-PHON and Divine Arsenal as Xyz finishers
• Turn 1 (going first): Opening Live Twin Ki-sikil or Lil-la to summon a second Live Twin, then Secret Password or Sunny's Snitch to search and build toward an Evil Twin Link (theoretical; no combo data)
• Turn 2 (going second): Open hand traps (Ash Blossom, Infinite Impermanence, Nibiru, Droll & Lock Bird, Maxx C) to answer the opponent's first summon, then rebuild the Live Twin line
• Recovery: Ghost Belle, Ash Blossom and Live Twin Lil-la Treat recur from GY, and Fiendsmith's Lacrima and Requiem re-enter from GY (Inferred from card text)
• After siding: Not evaluable: there are no side cards, so no post-side plan exists

Why it scores here

The list is Illegal under OCG rules (two Forbidden cards and an 18-card Extra Deck), so it receives a capped, theoretical score rather than a normal Final Contextual score. Structurally, the archetype core is well represented: the core-group hypergeometric estimate gives about 0.95 odds of at least one core card in a 5-card opener (Inferred), and the deck has 13 hand traps and 15 negation-text cards, which lifts interaction. Those strengths are offset by a low archetype purity (0 exact-name copies, 70 off-archetype copies across Fiendsmith, Unchained, Harpie, Knightmare, D/D and others), 21 tech cards diluting a 52-card main, and no recorded combos, so the floor and median are unknown and the ceiling is text-only. The score was not derived from Evil Twin's popularity, and card scores were not averaged into the deck result. There is no side deck and no tournament or win-rate data, so post-side adaptability and matchup fit score low and remain provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun secondary (not blended into weights). Structural ≈ 45, Going First ≈ 42, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); dependence on one Extra-Deck card (-2); engine conflicts (-2); illegal-list cap (-6). Final formula: Theoretical 0.80*45 + 0.20*35 = 43; modifiers -12 gives 31; Illegal cap applied, final 25 (structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core archetype group is highly accessible (0.945 for at least one core card in 5 cards)
• Dense interaction: 13 hand traps, 15 negation-text cards, 13 removal-text cards
• Recursion through Ghost Belle, Ash Blossom and Live Twin Lil-la Treat

Weaknesses

• Two Forbidden cards and an 18-card Extra Deck make the list illegal
• No side deck, so no post-side adaptation
• Low archetype purity (0% exact name) and 21 tech cards dilute the engine
• No combo or tournament data to confirm any line

Critical choke points

• Live Twin Ki-sikil or Lil-la opener, since the early Link line depends on it
• Evil Twin Link summons, which need specific Ki-sikil and Lil-la material

Recommended changes

Evidence & confidence

• Verified: Illegal status: Knightmare Gryphon and D/D/D Wave High King Caesar are Forbidden in OCG; Extra Deck count is 18, above the 15 maximum; Main Deck is 52 cards, inside the 40-60 range; Side Deck is empty; Archetype purity is 0% exact name, with 70 off-archetype copies; Card text and stats for the 52 distinct cards are as exported
• Inferred: Core-group opening-hand probability of about 0.945; Brick rate of about 5.5% for no core card; Going-second hand-trap coverage of 0.84; Live Twin and Evil Twin Link lines and recursion chains, derived from card text; Midrange primary strategy with Stun and Toolbox secondaries
• Provisional: Meta power (no dated metagame sample); Matchup fit and format fit (no tournament link)
• Data gaps: No combos supplied, so combo 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 exists in YGOVN (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null; deck name cannot be verified No side deck, so post-side plans cannot be evaluated
