Evil Twin/Live Twin/Evil★Twin/Live☆Twin Deck #773728 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Stun
• Secondary strategies: Combo, Toolbox
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Link and Fusion boards from Evil Twin and Fiendsmith Extra Deck monsters, with the board-clearing and negation suite protecting the summon; Chaos Angel and high-ATK Fusion/Link beaters once the board is cleared with Raigeki or Harpie's Feather Duster
• Turn 1 (going first): Open with Ki-sikil or Lil-la starters and Fiendsmith Engraver or Tract, holding hand traps (Ash, Impermanence, Veiler) for the opponent's first activation
• Turn 2 (going second): Use the six-card hand of hand traps (Ash, Ghost Ogre, Ghost Belle, Veiler, Evenly Matched) to negate or destroy the opponent's starter, then rebuild through the Extra Deck
• Recovery: Recursion from the GY through Lacrima, Lil-la Sweet, Fiendsmith's Requiem and Sequence, plus Fiendsmith Kyrie and in Paradise
• After siding: Not available: the deck has zero Side Deck cards, so there is no post-side plan

Why it scores here

The deck is scored as a system, not as an average of its cards. Its interaction suite is the standout: roughly 20 hand traps and negation cards, including Ash Blossom, Infinite Impermanence, Effect Veiler and Ghost Ogre, give it very strong going-second protection (about 94% chance of at least one hand trap in a six-card hand, per the hypergeometric estimate). The engine is weaker: it spans two archetypes (Fiendsmith and Evil Twin) plus a Mulcharmy/Live Twin bridge, with 28 distinct Main Deck cards and roughly 24 level-0 Spells and Traps that tend to brick opening hands. No combo boards were recorded, so the floor, median and ceiling are text-only inferences and not measured outputs. The score is capped because the list is illegal: three cards exceed their copy limits (Ash Blossom 3 vs 2, Fiendsmith Engraver 3 vs 1, Fiendsmith's Tract 2 vs 1), so only a theoretical, structural read is given. Archetype popularity and usage statistics were not used to raise the score.

Dimension scores

How the score was computed

Strategy profile: Stun primary, Combo secondary; no more than one secondary profile used, ratio not computed. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-8). Final formula: No reliable metagame: 0.80*Structural(53) + 0.20*TournamentReliability(42) = 51, then modifier -8 gives 43; capped at 30 because the list is Illegal (theoretical/structural-only, Step 2)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · key two-card combo ≈ — · full-brick estimate ≈ 0.11 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Very high interaction density, with about 20 hand traps and negation effects
• Strong going-second protection: about 94% chance of a hand trap in six cards
• High-ATK Extra Deck finishers (Trouble Sunny 3300, Chaos Angel 3500, Rextremende 3000)
• Board-breaking via Raigeki and Harpie's Feather Duster

Weaknesses

• Illegal as built: three cards exceed their copy limits
• Zero Side Deck cards, so no best-of-3 adaptation
• Two competing Extra Deck engines (Fiendsmith and Evil Twin) reduce coherence
• About 24 level-0 Spells and Traps and many hand traps create brick and dead-card risk

Critical choke points

• Fiendsmith Engraver and Fiendsmith's Tract: both over the copy limit, and the Fiendsmith line depends on them
• Live Twin Ki-sikil/Lil-la starters: few copies of the monsters that open the Evil Twin link line

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom (3 vs 2 legal), Fiendsmith Engraver (3 vs 1), Fiendsmith's Tract (2 vs 1); Main 55 and Extra 15 are within the TCG size rules; Side is 0; Card text and stats for all listed cards; Extra Deck breakdown: 11 Link, 3 Fusion, 1 Synchro
• Inferred: Hypergeometric opening-hand probabilities (starter at least one 0.89, hand-trap in six cards 0.94); Stun primary strategy with Combo secondary, from card roles; Interaction density (D7) and going-second strength (D8); Brick and pilotability estimates (D2, D14)
• Provisional: Matchup and format fit (D13); Meta Power (null)
• 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 are absent No win-rate telemetry exists (going-first/second, matchup, brick and starter rates) usage statistics in this deck flags disagree with the card list: Evil★Twin Ki-sikil, Lil-la, Ki-sikil Deal, Fiendsmith's Requiem, Sequence, Agnumday and others are shown in the Extra Deck but reported as not in this deck; treated as a stats-side inconsistency and not used to set scores Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
