Synchron Deck #771887 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 31/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro Summon a boss (Stardust Dragon, Shooting Majestic Star Dragon, Stardust Warrior, Satellite Warrior) from a Tuner plus non-Tuner materials, protected by hand traps and negations; Junk/Synchron recursion and Mulcharmy card advantage to grind the opponent out
• Turn 1 (going first): Open a Tuner and a non-Tuner (Synchron/Junk/Stardust), Normal Summon a searcher such as Junk Meister or Junk Synchron, search a second starter, and Synchro Summon a boss; hold Ash Blossom or Droll & Lock Bird for interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, D.D. Crow, Skull Meister, Ghost Ogre & Snow Rabbit, Nibiru) to disrupt the opponent's first summon, then rebuild a board through Synchro Summons and Mulcharmy draws
• Recovery: Recur Synchron/Junk monsters from the GY through Jet Synchron and Junk Signal effects, and redraw through Mulcharmy Fuwalos or Purulia when hands are empty
• After siding: No side deck is registered, so no post-side plan exists in this evidence

Why it scores here

The deck is a loose Synchron/Junk/Stardust/Mulcharmy build of 29 distinct main-deck cards, 15 hand traps and negations, and 14 Synchro monsters. Its probability estimates show a starter is live in about 25% of 5-card openings for any three-copy card, and roughly 69% of hands contain at least one searcher-text card, so it usually opens something but seldom a clean engine. Interaction is the strongest area: 15 hand traps give about 87% odds of at least one going second, which lifts end-board interaction. No recorded boards exist, so combo conversion and median output are text-only inferences and are scored low. Popularity and the archetype's usage record were not credited; the scores come from the system (consistency, interaction, and recovery) and not from averaging card scores. The list is illegal (three copies of Ash Blossom against a limit of two) and has no side deck, so the final score is capped and the evaluation is structural only.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 44, Going First ≈ 40, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Illegal copy limit (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Illegal cap applied) = 42.8 - 12 = 31

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 hand-trap and negation suite (15 hand traps, 16 negation-text cards)
• Multiple Synchro boss options with strong ATK and negation text
• Mulcharmy draw engine gives card advantage in long games

Weaknesses

• Illegal copy count on Ash Blossom
• Low exact-archetype purity; sub-archetypes do not share a single engine
• No side deck registered
• Snake-Eye Doomed Dragon is a likely dead Extra Deck slot

Critical choke points

• Ash Blossom over the copy limit must be fixed before the list can be scored normally
• Synchro Summon requires a Tuner and non-Tuner material; a missing Tuner stops the line

Recommended changes

Evidence & confidence

• Verified: Main deck 55 cards, Extra 15, Side 0; within OCG size rules; Ash Blossom & Joyous Spring: 3 copies run, 2 legal (violation); Droll & Lock Bird and Reinforcement of the Army are Limited with 1 copy each (legal); Archetype purity 1.4% exact-name; 69 off-archetype copies
• Observed: Mulcharmy Fuwalos usage 60.6%, Droll & Lock Bird 56.3% (archetype usage statistics)
• Inferred: Starter access probabilities (25% for 3-copy cards in 5 cards); Brick risk from level-0 spells/traps and the mixed sub-archetype engine; Interaction quality from negation text and hand-trap count
• Provisional: Meta and matchup fit; no dated metagame sample
• 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 (first/second, matchup, brick/starter rates) Meta Power is provisional without a dated metagame sample No side deck registered, so best-of-3 adaptability is unscored
