Synchron Deck #756754 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Medium)

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

Legality

Main 43 / Extra 16 / Side 0 — status: Illegal. 9 violation(s).

Identity & game plan

• Win condition: Kewl Tune and Elfnote Synchro boards (Kewl Tune B2B, June Pride, Junora) built through tuner-based Synchro Summons; Elfnote and Kewl Tune Special Summon engines feeding high-ATK Synchro monsters
• Turn 1 (going first): Open a Tuner starter (Kewl Tune Cue/Mix/Reco or Elfnote Tinia/Lucina) with a searcher, then Synchro Summon into a board-building Extra Deck monster. Hold Ash Blossom or Droll for the opponent's first activation.
• Turn 2 (going second): Use hand traps (Ash Blossom, Effect Veiler, Ghost Ogre, Droll & Lock Bird, Ghost Belle) to stop the opponent's starter, then rebuild through Duelist Genesis or Kewl Tune searchers.
• Recovery: Recover with Kewl Tune Mix/Reco searchers, Kewl Tune Track Maker and Remix from the Extra Deck, and Synchro Overtake to fetch a Synchro monster.
• After siding: No Side Deck is registered, so no post-side plan can be evaluated.

Why it scores here

The deck is scored as a connected system. The Kewl Tune and Elfnote engines have searchers (P(at least one searcher-text card in a 5-card hand) ≈ 0.97) and a 3-copy Ash Blossom with Effect Veiler and Droll give strong going-second interaction (P(at least one hand trap in a 6-card hand) ≈ 0.90). The two engines split the Main Deck: 59 of 64 copies are off the Synchron archetype name, and no core Synchron monsters are present, so the engine is less coherent than the sub-archetype counts suggest. Without recorded combos, the ceiling and median are inferred from text only. The Illegal status (8 over-limit or Forbidden copies, Extra Deck 16 > 15) caps the final score. Popularity and archetype usage did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Stun secondary (no pure blend); weights used from the Combo profile. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-12); Dependence on Extra Deck overflow (0). Final formula: Illegal cap applied. Uncapped 0.80*52 + 0.20*40 = 49.6, minus 12 for banlist exposure = 37.6, then capped at 20 as theoretical/structural-only (Illegal list)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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

• Strong searcher density (20 searcher-text cards) keeps the engine findable
• Layered hand-trap interaction (13 cards) is strong going second
• High-ATK Synchro finishers (Kewl Tune B2B 3200, June Pride 3100, Junora 3100)

Weaknesses

• Illegal copy counts and Forbidden cards
• Two engines (Kewl Tune and Elfnote) with little cross-support
• No core Synchron monsters despite the Synchron archetype label
• No Side Deck

Critical choke points

• Kewl Tune Tuner starters are the first step for most lines and are over-limited
• Extra Deck of 16 cannot be legally built

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal; Forbidden cards Kewl Tune Rotary and PSY-Framelord Omega present; Copy limits exceeded for 6 Limited and 1 Semi-Limited card; Extra Deck 16 exceeds the 15 maximum; Main Deck 43 within 40–60; No Side Deck (0 cards); Card text and stats for all 37 distinct cards
• Observed: Usage stats: Ash Blossom 100% inclusion, Droll & Lock Bird 100%, Ghost Ogre 75%, Ghost Belle 50% (archetype-level only)
• Inferred: Starter and searcher probabilities from hypergeometric estimates; Hand trap coverage (Ash, Veiler, Ghost Ogre, Droll, Ghost Belle); Brick risk from Tuner-dependent hands; Engine split between Kewl Tune and Elfnote
• Provisional: Meta Power (no dated metagame); Matchup fit (D13) (no tournament link)
• Data gaps: No recorded combos; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry; going-first/second and matchup signals are Inferred Meta Power is Provisional without a dated metagame sample No Side Deck registered; post-side plan cannot be evaluated
