Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Synchro Summon high-ATK Kewl Tune and Synchro bosses (Kewl Tune B2B 3200 ATK, Visas Amritara 2500, Enigmaster Packbit 2900, Zalen 2800) off a Tuner-heavy opening; Going-second hand-trap disruption (Ash Blossom, Effect Veiler, Ghost Belle, Ghost Ogre, Droll) leading into a Synchro follow-up
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner (Cue, Reco, Mix or Clip), use its search or special summon, and Synchro Summon a boss from the Extra Deck using the Kewl Tune Synchro or Over Tuning chain
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler or Ghost Belle for the opponent's first engine activation, then convert the surviving Tuner into a Synchro Summon
• Recovery: Rebuild from the Graveyard: Kewl Tune Reco and Mix add Kewl Tune monsters from the Deck or GY, and Pot of Desires or Pot of Prosperity refuel the hand
• After siding: No Side Deck is registered, so there is no post-side plan; the list cannot adapt between games

Why it scores here

The deck opens the Kewl Tune core in most hands: the hypergeometric estimate for at least one archetype-core card in a 5-card opening hand is about 0.95, and 17 searcher-text cards add a second route to the engine. Its ceiling comes from Synchro bosses that have strong stats and recovery text, but no recorded boards exist, so combo output is text-only inference. Interaction is broad (15 hand traps and 11 negation-text cards), which supports going-second survival, while the 26 Tuners and the 3-copy Kewl Tune Synchro and Reco lines raise brick and conflict risk. The score is capped at 35 because the list is illegal on copy limits; it does not come from the Kewl Tune archetype's popularity, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-6); No side deck (-3). Final formula: Pre-cap: 0.80*Structural(57) + 0.20*TournamentReliability(50) + modifiers(-9) = 46.6, meta provisional. Capped at 35 because the list is Illegal (copy-limit violations), so the score is theoretical/structural-only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Core archetype access is high (about 0.95 for at least one core card in an opening hand of 5)
• Layered hand-trap and negation density supports going-second disruption
• Synchro boss stats and recovery text give a real closing ceiling
• Extra Deck is coherent around the Kewl Tune Synchro theme (13 of 15 cards are Synchro)

Weaknesses

• Illegal copy limits on five cards, including a Forbidden card
• Only 34.3% exact-name archetype purity; 46 off-archetype copies
• Tuner-heavy opening hands risk conflicting Normal Summons and dead Tuners
• No Side Deck

Critical choke points

• Kewl Tune Rotary is Forbidden; any Kewl Tune Tuner-chain line that relies on it is illegal and must be removed
• Dependence on Kewl Tune Synchro and Reco as the first Tuner-to-Synchro link
• No recorded combos to confirm that a typical opening reaches a boss

Recommended changes

Evidence & confidence

• Verified: Illegal status: five cards over their copy limits, including Kewl Tune Rotary (Forbidden); Main 55, Extra 15, Side 0 within size rules; Archetype core and hand-trap probabilities from the hypergeometric table; Extra Deck composition: 14 Synchro, 1 Fusion
• Inferred: Opening-hand consistency and brick rate from the probability table and Tuner density; Going-second strength from hand-trap density; Interaction quality from negation and removal text
• Provisional: Meta position and matchup fit; no tournament or dated meta sample is available
• 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: going-first, going-second and matchup rates are unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered, so post-side adaptability cannot be assessed
