Synchron Deck #752172 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Control, Stun
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Synchro summon Kewl Tune and high-ATK Synchro/XYZ boss monsters (Kewl Tune B2B, Super Starslayer TY-PHON, Enigmaster Packbit) off Tuner-heavy openings; Hand-trap-protected board of Tuners that recurs through the Kewl Tune searchers and Synchro Materials
• Turn 1 (going first): Open a Tuner, Normal Summon Kewl Tune-family monsters or search via Kewl Tune Synchro/Mix/Reco, then Synchro Summon a Kewl Tune boss; hold Ash/Impermanence/Veiler for the opponent's first activation. Starter odds are low on a 5-card hand (about 25% per 3-copy card).
• Turn 2 (going second): Use the six-card hand's hand-trap density (about 87% to hold at least one hand trap) to negate the opponent's first engine activation, then rebuild with Kewl Tune searchers and Synchro Summon.
• Recovery: Recover via Kewl Tune Mix/Reco/Clip searches, Duelist Genesis, and Pot of Desires/Sloth draws, plus Tuner recursion from the GY and banish costs on Kewl Tune Track Maker and RS.
• After siding: No Side Deck is registered (side_count 0), so there is no post-side plan. Without a legal Side the deck cannot adapt between games in a best-of-3.

Why it scores here

This list is Illegal under the TCG BanList: eight copy-limit violations, including three Forbidden cards (Kewl Tune Rotary x3, Called by the Grave, Triple Tactics Talent). The rubric therefore caps it at a theoretical, structural-only score rather than a normal contextual score. Structurally, the deck opens reliably on hand traps and Kewl Tune searchers (about 87% chance of at least one hand trap going second) but has low per-card starter odds on the going-first five-card hand (about 25% per 3-copy card). It has 15 interaction and negation cards and a 14-card Synchro Extra that can reach strong boss monsters, but a 26-Tuner main deck and no Side Deck make its recovery and post-side play weak. Popularity did not earn points: Synchron usage stats confirm the archetype core is accessible, but they do not make the list stronger, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Control as secondary context only; Structural = Σ(dimension × Midrange weight)/100 = 52. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); no side deck (0). Final formula: Illegal: no normal contextual score. Raw formula 0.80·52 + 0.20·40 = 49.6; banlist exposure −6 → 43.6; illegal cap applied → 35 (theoretical/structural only, Meta provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Hand-trap density: 15 hand traps, with about 87% chance of at least one going second
• Synchro boss suite: Kewl Tune B2B (3200), TY-PHON (2900), Packbit (2900), Zalen (2800)
• Draw and grind engines: Pot of Desires, Pot of Sloth, Mulcharmy Fuwalos/Purulia

Weaknesses

• Illegal list: eight copy-limit violations including three Forbidden cards
• No Side Deck, so no post-side adaptation
• Low single-card starter odds (about 25% per 3-copy card on going first)
• 26 Tuner monsters create Normal Summon and Synchro-material conflicts

Critical choke points

• Kewl Tune Synchro/Mix/Reco searchers: copy-limit cuts reduce the searchers that find the Synchro boss
• Tuner density in hand: a hand of Tuners without a non-Tuner partner stalls the Synchro Summon

Evidence & confidence

• Verified: Legality status Illegal, copy-limit violations and banlist statuses from the evidence; Main 55 / Extra 15 / Side 0 sizes and composition; Usage stats: Ash Blossom 100%, Droll & Lock Bird 100%, Called by the Grave 100%; Card text and ATK/DEF values for the listed boss monsters
• Inferred: Hypergeometric starter, brick and hand-trap probabilities; Strategy classification as Midrange with Control/Stun secondary; Interaction and resilience estimates from card text; Pilotability complexity estimate
• Provisional: Meta Power (no dated metagame sample); D13 matchup fit and tournament reliability (no tournament link); Post-side plan (no Side Deck)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot records are absent No win-rate telemetry for going-first/second, matchup, brick or OTK rates Meta Power is provisional without a dated metagame sample No Side Deck: post-side performance cannot be assessed Deck title is null
