Synchron Deck #772796 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Midrange
• Format: ocg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro Summon Stardust/Junk/Majestic-style Extra Deck boss monsters (Shooting Majestic Star Dragon, Accel Synchro Stardust Dragon, Stardust Warrior) off a Tuner plus non-Tuner base, with Junk Synchron and Stardust Synchron as Tuner access; Mulcharmy draw-engine pressure and card advantage from Pot of Sloth and searchers
• Turn 1 (going first): Open on a searcher (Junk Meister, Full-Speed Warrior, Assault Sonic Warrior, Psi-Reflector, Stardust Synchron) to fetch Junk Synchron or Stardust tuners, then Synchro Summon a Stardust or Junk boss; hand traps are held for the opponent's first activation
• Turn 2 (going second): Use Ash Blossom, Ghost Ogre & Snow Rabbit and Droll & Lock Bird to answer the opponent's opening, then convert the remaining resources into a Synchro Summon
• Recovery: Recur Tuners from the GY via Jet Synchron, Junk Synchron and Stardust Trail, and rebuild the Synchro board from Synchro Emergency and Synchro Rumble
• After siding: Not evaluable: the deck runs no side deck (Side Deck size 0), so there is no post-side plan

Why it scores here

The deck's structural score comes from its system as a whole: a searcher-dense Main Deck (15 searcher-text cards, about 80% chance of at least one in a 5-card opening hand) reaches a Tuner in the Extra-Deck-linked Synchro lines, and it has several overlapping sub-archetype routes (Junk, Stardust, Mulcharmy, Greed) so one interruption does not end the turn. Interaction is layered across hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird), backrow removal and two Extra-Deck negates, and the Extra Deck supplies high-ATK closers. The score is held back because the list is Illegal: Ash Blossom is run three times against a limit of two, so this is a theoretical/structural read only. No combo boards, tournament link, or side deck exist, so consistency and conversion are Inferred and the score carries a large uncertainty band. Popularity signals were not used to raise the score, and no card scores were averaged into it.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 55, Going First ≈ 56, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: copy-limit violation (-10); no side deck (-2). Final formula: Illegal deck, theoretical/structural-only: 0.80*Structural (55) + 0.20*TournamentReliability (40) + ContextModifiers (-12) = 40; Meta Power provisional (null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · 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 searcher and Tuner access (15 searcher-text cards, about 80% at least one in opening 5)
• Layered interaction: hand traps, backrow removal and two Extra-Deck negates
• Strong Extra-Deck closers, including Shooting Majestic Star Dragon at 4000 ATK

Weaknesses

• Illegal as built: Ash Blossom & Joyous Spring is over the Semi-Limited copy limit (3 vs 2)
• No side deck, so no best-of-3 adaptation
• Low exact-archetype purity (1.4%), so engines rely on cross-sub-archetype support

Critical choke points

• Ash Blossom copy count makes the list tournament-illegal as built
• Tuner availability for Synchro Summons depends on a small set of Junk and Stardust Tuners

Recommended changes

Evidence & confidence

• Verified: Main Deck 56 and Extra Deck 15 are within size rules; Ash Blossom & Joyous Spring is over the Semi-Limited copy limit (3 vs 2); Side deck is empty; Card stats and text from the evidence pack
• Observed: Usage: Mulcharmy Fuwalos and Droll & Lock Bird are core cards at 53% inclusion
• Inferred: Starter consistency (hypergeometric) and brick risk; Dimension scores D1 to D9 and D11 to D14 (Inferred from text and composition); Overall Toolbox weighting and going-first and going-second estimates
• Provisional: Meta Power (null, no dated metagame sample); Format fit (D13) and tournament reliability
• Data gaps: No combos supplied, so 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 for going-first, going-second, matchup or brick/starter rates Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered, so post-side plans cannot be evaluated
