Synchron Deck #772211 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Synchro Summon large-attack Extra Deck monsters (Shooting Majestic Star Dragon, Cosmic Blazar Dragon, Bystial Dis Pater, Stardust Dragon) off Synchron, Junk and Stardust tuner lines; Hand-trap-supported tempo: stop the opponent's first summon or activation, then convert the Synchro board
• Turn 1 (going first): Open a tuner and one non-tuner, search via Tuning, Junk Converter, Synchro Fellowship or Stardust Synchron, then Synchro Summon Stardust Dragon or Junk Warrior and hold Ash Blossom / Effect Veiler for the opponent's first interaction
• Turn 2 (going second): Use the six-card hand's hand traps (Ash Blossom, Effect Veiler, Droll & Lock Bird, Infinite Impermanence, Nibiru) to break the opponent's first summon chain, then rebuild a Synchro board from the remaining hand
• Recovery: Recover from a single-card loss via recursion: Junk Synchron and Anchorbolt Hedgehog from the GY, Stardust Trail when a monster is Tributed, Junk Converter from the GY as Synchro material
• After siding: Not applicable: the deck has no Side Deck, so no post-side plan exists

Why it scores here

The deck is scored on its system, not on an average of its cards. Starter access is reasonable: 18 searcher-text cards give about 0.87 odds of at least one searcher in a 5-card opening, so a tuner and a Synchro line are usually reachable by turn 2 (Inferred). Interaction is the strongest part of the system: 13 negation-text cards, 14 hand traps and 21 removal-text cards give a dense, layered interaction suite. Closing power is real (Shooting Majestic Star Dragon and Cosmic Blazar Dragon at 4000 ATK) but depends on Extra Deck access. The score is held down by the main deck's 55 cards, the 23 singleton slots, the lack of any Side Deck, and the illegal list: Droll & Lock Bird is over its OCG limit and two Forbidden cards are run, so the Final score is capped low and is theoretical only. Popularity (53% core inclusion for Mulcharmy and Droll) confirms the list is real but did not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no Side Deck (-4); illegal_list_cap (0). Final formula: No reliable metagame: 0.80*Structural(57) + 0.20*TournamentReliability(45) = 54.6; modifiers total -12 gives 42.6; Illegal-list cap applied, final score set to 30 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · 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: 14 hand traps plus 13 negation-text and 21 removal-text cards
• Searcher density (18 searcher-text cards) gives high starter access
• Strong Extra Deck closers at 3500-4000 ATK
• Flexible 15-card Synchro Extra Deck with multiple Level and Attribute options

Weaknesses

• Illegal list: Droll & Lock Bird over its OCG limit; two Forbidden cards run
• 55-card main deck is bloated with 23 singleton slots, raising brick risk
• No Side Deck, so no post-side adaptability
• Weak exact-archetype coherence (Synchron purity 1.4%), so engine lines overlap less than the card count suggests

Critical choke points

• Extra Deck access: most closers need specific Synchro materials and a live tuner
• Hand-trap dependence on going second: a missed hand trap leaves the first summon unanswered
• Forbidden Crystal Wing and Baronne cannot be played legally, so their roles must be replaced before the list is legal

Recommended changes

Evidence & confidence

• Verified: Main Deck size 55 and Extra Deck size 15 (within the 40-60 and 0-15 OCG rules); Forbidden cards Crystal Wing Synchro Dragon and Baronne de Fleur are run; Droll & Lock Bird is run 3 copies against a limit of 1; Zero Side Deck cards; Archetype usage: Mulcharmy Fuwalos and Droll & Lock Bird at 53% inclusion
• Inferred: Starter access 0.87 for searcher text in a 5-card hand; Hand-trap density 0.84 for going second; Interaction density from card text; Brick risk from the 55-card main with 23 singletons
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link and no meta sample)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup, game-level, brick/starter/OTK rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck present: post-side evaluation impossible
