Synchron Deck #754231 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Synchro
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 9 violation(s).

Identity & game plan

• Win condition: Synchro Summon end-boards such as Kewl Tune B2B (3200 ATK), Visas Amritara and Zalen, backed by Kewl Tune Synchro/Reco/Cue starters; Fusion (Mixousia, Sea Monster of Theseus) and Link (S:P Little Knight) as alternate Extra Deck threats
• Turn 1 (going first): Open a Kewl Tune Tuner, use a searcher (Kewl Tune Mix, Kewl Tune Reco, Kewl Tune Synchro, Duelist Genesis) to build a second Tuner, then Synchro Summon a Kewl Tune boss. Requires the 3-copy Limited/Forbidden cards, so it is not legally reproducible as listed.
• Turn 2 (going second): Respond to the opponent with hand traps (Ash Blossom, Ghost Belle, Effect Veiler, Droll & Lock Bird, Ghost Ogre) and then rebuild through Kewl Tune Loudness War or B2B. No evidence of a real going-second board.
• Recovery: Searchers (18 searcher-text cards) and recursion from the GY (Kewl Tune Mix, Kewl Tune Reco, Bystial Magnamhut) to rebuild after interruption. Strength is unverified because no board data exists.
• After siding: No Side Deck (side_count 0). Best-of-3 adaptation is not possible as built.

Why it scores here

The deck is Illegal in TCG: nine entries exceed their copy limits, and three copies of the Forbidden Kewl Tune Rotary are run. Under the Illegal rule it is capped and scored as a structural-only read. The Structural score (53) comes from the Combo weight profile on the system: the Kewl Tune Tuner engine and its searchers (18 searcher-text cards, archetype core about 65% to have one in hand of five) give reasonable access, and 15 hand traps plus 11 negation-text cards give interaction that holds up through interruption. The Extra Deck (15 cards, mostly Kewl Tune Synchros with Kewl Tune B2B at 3200 ATK) offers real end-board power. Popularity and archetype share did not earn points, since no tournament data exists, and card scores were not averaged. The main limits are that the engine depends on 3-copy Limited and Forbidden cards that cannot be played legally, that there is no Side Deck, and that there are no combo boards, so the floor and median are inferred from text only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53.2, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10). Final formula: Illegal cap applied (theoretical / structural-only). Uncapped: 0.80*53.2 + 0.20*45 - 10 (banlist exposure) = 41.6; capped to 30. Meta Power provisional/null (no dated metagame, no tournament link).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.65 · 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

• Dense interaction suite: 15 hand traps and 11 negation-text cards, giving several answers to one interruption.
• High searcher density (18 searcher-text cards) with a 65% chance of having an archetype core card in the opening five.
• Strong Extra Deck end-boards: Kewl Tune B2B (3200 ATK), Zalen (2800 ATK), Visas Amritara (2500 ATK) and Kewl Tune Loudness War (3000 DEF).

Weaknesses

• Illegal list: nine copy-limit violations, including three Forbidden Kewl Tune Rotary.
• The engine relies on 3-copy starters that are Limited to 1 legal copy (Cue, Synchro, Reco), so legal redundancy is much lower than the list suggests.
• No Side Deck, so best-of-3 adaptation is not possible.
• No recorded combos or tournament data, so floor, median and matchup scores are inferred from text.

Critical choke points

• Kewl Tune Rotary (Forbidden, 3 copies) and Called by the Grave (Forbidden) cannot be played in the format as listed.
• Limited Kewl Tune Cue, Synchro and Reco: legal limit 1 each, so a single starter is a choke point.

Recommended changes

Evidence & confidence

• Verified: Legality: 9 copy-limit violations; 55 Main, 15 Extra, 0 Side.; Forbidden: Kewl Tune Rotary, Called by the Grave, Anti-Spell Fragrance.; Card text and stats for the listed cards (for example B2B 3200 ATK, Zalen 2800 ATK).; Archetype core usage: 22 core cards, 5 present (usage_statistics).
• Inferred: Engine consistency (hypergeometric estimates).; Interaction and recovery quality from card text.; Going-first and going-second strength, and the combo ceiling and median.
• Provisional: Meta Power and format fit: no dated metagame and no tournament link.
• Data gaps: Illegal list: copy-limit violations must be fixed before a normal Final score applies. No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot record are absent. No win-rate telemetry: going-first/second, matchup, brick and OTK rates are Inferred or Unknown. Side Deck is empty: post-side plan cannot be evaluated. Meta Power is provisional unless a dated metagame sample is supplied.
