Evil Twin Deck #770014 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±7 · Confidence: Medium)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro and Link beatsticks from the Kewl Tune and Evil Twin extra-deck pool (Kewl Tune B2B 3200 ATK, Evil Twin's Trouble Sunny 3300 ATK, A Bao A Qu 2800 ATK), with Live Twin Snitch chip damage; Kewl Tune Loudness War protecting Tuners from card effects, plus Live Twin LP-drain text
• Turn 1 (going first): Open a Kewl Tune or Tuner starter (Kewl Tune Mix, Kewl Tune Cue, Kewl Tune Rotary, Effect Veiler) that searches a Kewl Tune card, then Synchro or Link into a board while holding hand traps (Ash Blossom, Impermanence, Effect Veiler) for the opponent's first activation (Inferred)
• Turn 2 (going second): Hold 13 hand traps in the 6-card hand to answer the opponent's first board, then rebuild through Tuner recursion (Ghost Belle, Ghost Ogre, Kewl Tune Track Maker) into a Synchro or Link (Inferred)
• Recovery: Recur Tuners from the GY through Ghost Belle and Ghost Ogre, Kewl Tune Reco or Mix searches, and Synchro Summons that re-spend GY Tuners (Inferred)
• After siding: No side deck is registered, so there is no documented post-side plan; a best-of-3 build must be assembled from scratch

Why it scores here

The deck is scored as a connected Midrange system. Its engine is a Tuner web: Kewl Tune Mix, Cue, Rotary, Reco and Clip plus Kewl Tune Synchro and three Kewl Tune Mix copies give a 32% chance of a Mix in the opening five (Inferred hypergeometric), and the searcher text group reaches about 97% in the opening five, which says the deck finds cards but not that the combination is reliable. Its interaction is the strongest part of the system: 13 hand traps (Effect Veiler, Ash Blossom, Impermanence, Ghost Ogre, Ghost Belle, Maxx C, Droll and Lock Bird) give about 91% at least one hand trap as a going-second 6-card hand, and Kewl Tune Loudness War protects Tuners from card effects. Its ceiling comes from Synchro and Link beatsticks (B2B, Trouble Sunny, A Bao A Qu, Zalen), but no recorded boards exist, so the ceiling and floor are text-only inference. The deck earns no points from Evil Twin popularity: the archetype purity is 0% exact-name and the list mixes Kewl Tune, Live Twin, Evil Twin, Blue-Eyes, Synchron and C, which is an engine conflict. The score was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 57, Going Second ≈ 61, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-2); engine conflicts (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Final = 0.80*58.7 + 0.20*52 = 57.3, then modifiers -5 = 52

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · 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

• Legal OCG list at legal minimum main size (42) with Extra at 15 and 0 Limited/Forbidden overruns
• 13 hand traps plus Effect Veiler and Ghost Ogre/Belle give strong going-second interaction
• Tuner recursion through Ghost Belle, Ghost Ogre and Track Maker gives resilience after the first interruption
• Extra-deck threats above 2800 ATK (B2B, Trouble Sunny, A Bao A Qu) plus Loudness War tuner protection

Weaknesses

• No side deck: best-of-3 adaptation is zero (D12 = 15)
• Engine conflicts across Kewl Tune, Live Twin, Evil Twin, Blue-Eyes, Synchron and C sub-archetypes
• Heavy dependence on specific Limited Kewl Tune cards (Cue, Rotary, Reco, Synchro, Maxx C) at 1 copy each
• No recorded combo or win-rate data, so floor and median are unknown

Critical choke points

• Kewl Tune Mix (3 copies) as the main searcher into Kewl Tune Synchro, Remix and Crackle
• Tuner count (about 21 in main) without a registered side deck to recover from a hand-trap mismatch
• Extra Deck Link monsters need Ki-sikil or Lil-la material, which is only partly run in main

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 42 Main, 15 Extra, 0 Side; all Limited copy counts respected (Droll and Lock Bird, Kewl Tune Cue, Reco, Rotary, Synchro, Maxx C, Reinforcement, Terraforming at 1; Ash Blossom at 2); Card text and banlist status for all 39 distinct cards listed in evidence; Hypergeometric draw table for the resolved Main Deck
• Inferred: Midrange profile and secondary Stun/Toolbox labels from role-tag counts; Engine accessibility, brick and resilience scores from starter probabilities and hand-trap density; Going-first and going-second plan text from card text; Ceiling and interaction scores from Synchro/Link text and negation/removal text
• Provisional: Meta Power (null) and matchup fit D13 (no dated metagame sample, no tournament link); Floor and median output D4 (no recorded boards)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — brick, starter, matchup and going-first/second rates are Inferred or Unknown no side deck registered (Side Deck size 0): D12 has no post-side evidence usage statistics.core_cards_present reports 5 of 18, but Extra-Deck core cards (A Bao A Qu, Trouble Sunny, Ki-sikil Deal, Lil-la, Ki-sikil) are in the Extra list with the same card_ids and are flagged in this deck=false, so the count looks main-deck-only; a manual count gives about 10 of 18 present (Inferred) deck title is null and the only guide (topic 500) is about a Spright build that this list does not run Meta Power is Provisional unless a dated metagame sample is supplied
