Synchron Deck #750938 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Synchro-summon large Extra Deck beaters (Stardust, Majestic Star, Accel Synchro) off a Tuner-heavy Synchron/Junk engine; Hand-trap-protected Synchro follow-up once the opponent's interaction is spent
• Turn 1 (going first): Normal Summon a Tuner (Junk Meister, Stardust Synchron or Ghost Belle) to reach a Synchro Summon through Junk/Synchron searches, keeping Ash Blossom and Droll up as hand traps (theoretical; deck is illegal as built)
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre and Droll to break the opponent's starter, then Synchro Summon through the surviving board
• Recovery: Recycle Tuners from the GY through Jet Synchron and Scrap Synchron effects, and rebuild a Synchro via Junk Synchron and Stardust Synchron's searches
• After siding: Not evaluable: the deck runs zero Side Deck cards

Why it scores here

As built the deck cannot be scored as a legal list: five Forbidden cards and three copy-limit overages make it Illegal, so the score is capped at 25 and labelled theoretical and structural-only. Its consistency comes from a large Tuner pool (about 16 Tuners in the Main Deck), giving roughly an 83% chance of at least one Tuner in a 5-card opening hand (Inferred, hypergeometric). Its interaction is dense (about 11 hand traps and 15 negation-text cards), which earns credit on going second. Its ceiling and median output are not scored from data because the export contains no recorded boards, so those dimensions are text-only inference. Popularity of the Synchron archetype and the 15-card synchro Extra Deck were not treated as proof of strength, and no card scores were averaged into the deck score. The 25 cap reflects the illegal list; a legal rebuild would need to be re-evaluated.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (no weight shift applied). Structural ≈ 54, Going First ≈ 52, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-12). Final formula: Illegal cap: 0.80*Structural(54) + 0.20*TournamentReliability(50) + Modifiers(-12) = 41, capped at 25 for an Illegal list (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · 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

• Large Tuner pool gives high Synchro access on the opening hand
• Layered hand-trap and negation coverage, strongest on going second
• Synchro Extra Deck covers many levels and attributes

Weaknesses

• Illegal as built: Forbidden cards and copy-limit overages
• 25 zero-level spells/traps weaken compactness
• No Side Deck, so no post-side adaptation
• No recorded boards, so the combo ceiling cannot be measured

Critical choke points

• Ash Blossom and Droll are the main hand-trap answers, and the illegal copy counts must be cut to legal limits before this list is playable

Recommended changes

Evidence & confidence

• Verified: Main 56 / Extra 15 / Side 0 composition and copy counts; Five Forbidden cards and three copy-limit overages in the legality check; Card stats and text for the listed Extra Deck Synchro monsters
• Inferred: Tuner-access probability (about 0.83) from hypergeometric estimate; Interaction density read from card text; Going-first vs going-second estimates; Synchro payoff conversion from text
• Provisional: Matchup and format fit (no dated meta or tournament data); Meta Power (null)
• Data gaps: No combos supplied: 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, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck has no Side Deck cards; post-side dimension is unscorable
