Synchron Deck #772731 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 45 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon a 4000-ATK boss (Stardust Sifr Divine Dragon or Shooting Quasar Dragon) off a Tuner plus non-Tuner board; Junk Warrior Extreme (2900 ATK) and Stardust Dragon/Stardust Warrior as Synchro bodies from Junk and Stardust lines
• Turn 1 (going first): Tuning or Duelist Genesis to fetch a Tuner, Junk Meister or Full-Speed Warrior to add Junk Synchron, then Synchro Summon into a boss; hand traps held for the opponent's first activation
• Turn 2 (going second): Use hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Synchro Emergency) to answer the opponent's starter, then rebuild through searchers into a Synchro Summon
• Recovery: Searchers (Synchro Fellowship, Junk Meister, Full-Speed Warrior, Assault Sonic Warrior) and the GY-Tuner recursion route (Junk Synchron, Scrap Synchron) rebuild after a hand trap or board wipe; no recorded lines confirm these work
• After siding: Not evaluable: the deck has no side deck

Why it scores here

The deck is scored as a system and not as an average of its cards. Its Synchro core is reasonably accessible: a 3-copy starter has roughly a 30% chance of appearing in a going-first opening hand, and there are enough Tuners to build a 2-card bootstrap, which keeps D1 near 50 (Inferred). It converts into 4000-ATK bosses from the Extra Deck, and it has layered hand-trap interaction (about 9 hand traps and 16 negation-text cards). Those strengths are offset by a split engine: only 5% of the main deck carries the exact Synchron name, the rest spans Junk, Stardust, Scrap and generic cards, and 15 of its 26 distinct main-deck cards are singletons, so the lines are fragile and bricks are likely. The deck is illegal as submitted because Ash Blossom runs 3 copies against an OCG limit of 2, which caps the score. Popularity did not earn points: the archetype usage statistics show that its core cards are absent, and no tournament or meta data supports a matchup read.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (disclosed; weights taken from Midrange profile). Structural ≈ 46.6, Going First ≈ 42, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist and copy-limit exposure (-6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 37.3 + 7 = 44.3; then Illegal cap applied (copy-limit violation): final capped at 30; theoretical/structural-only evaluation

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.3 · 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

• Two 4000-ATK Synchro bosses (Stardust Sifr, Shooting Quasar) plus several 2500-3300 ATK Synchro bodies
• Layered interaction: about 9 hand traps and 16 negation-text cards
• Recursion through GY Tuners and searchers for rebuilding

Weaknesses

• Illegal as submitted: Ash Blossom at 3 copies over the OCG limit of 2
• No side deck, so no post-side adaptability
• Split engine: 5% exact-name purity and 15 singleton main-deck cards
• Core usage cards (Mulcharmy Fuwalos, Droll & Lock Bird) are absent

Critical choke points

• Needing a Tuner plus a non-Tuner on board for every Synchro Summon, with Extra Deck access blocked by the Tuner-only restrictions on several effects
• Dependence on a few Synchro bosses in the Extra Deck with no alternate Extra Deck payoff recorded

Recommended changes

Evidence & confidence

• Verified: Main deck 45 cards, Extra 15, Side 0 (within OCG size rules); Ash Blossom & Joyous Spring runs 3 copies; OCG limit is 2 (Semi-Limited); Restricted cards: One for One, Reinforcement of the Army, Synchro Overtake (Limited, 1 copy each); Extra Deck contains 15 Synchro monsters with 4000-ATK bosses
• Observed: One guide exists for the archetype, with a comment that the list is brick-prone and unstable
• Inferred: Starter access probabilities from the hypergeometric draw table; Midrange primary strategy from hand-trap density and Synchro boss count; Brick risk from singleton count and archetype purity
• Provisional: Meta Power: no dated metagame sample; Matchup fit: no tournament data
• 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, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied no side deck: post-side plan cannot be evaluated
