Synchron Deck #765247 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Synchro
• Format: tcg

Legality

Main 57 / Extra 18 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Extra Deck Synchro beaters (Bystial Dis Pater, Shooting Majestic Star Dragon, Psychic End Punisher, Trishula, Kewl Tune B2B) summoned off Elfnote and Junk starters plus Synchron tuners; Stardust and Crimson Dragon board presence through Synchro Summon recursion
• Turn 1 (going first): Turn 1: Special Summon an Elfnote monster from hand, search or summon a second starter through Elfnote Lucina/Regina/Tinia effects, then Synchro Summon a 2400+ ATK boss; Ash Blossom and Droll & Lock Bird hold up interaction
• Turn 2 (going second): Use Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird and Nibiru as hand traps to break the opponent's first combo, then rebuild a Synchro board from the remaining starter
• Recovery: Synchron and Junk tuners recur from the GY (Jet Synchron, Starjunk Synchron, Junk Meister search) and Stardust Synchron and Mulcharmy draw cards to refill the hand
• After siding: Not defined: the deck has no Side Deck, so there is no post-side plan (structural gap)

Why it scores here

The deck scores as a system: its archetype core (18 copies, about 86% chance of at least one in a 5-card opening hand) gives it reliable Elfnote and Junk starters, and the 18-card Synchro Extra supplies several high-ATK finishers. Interaction is dense, with 9 hand traps and roughly 11 negation-text cards, which keeps the first combo from resolving cleanly. Recovery depends on Synchron and Junk recursion and card draw from Mulcharmy and Pot of Sloth. Structural points are capped because the list is illegal (3 copies of a Limited card, 3 copies of a Semi-Limited card, and 18 Extra Deck cards against a limit of 15), so the theoretical score is reported as a structural-only read. Popularity and archetype usage did not earn points, card scores were not averaged, and no combo or win-rate data supports a higher score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 56, Going Second ≈ 53, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6); Extra Deck over size (-2); No side deck (-2); Engine conflicts (-2). Final formula: No reliable metagame: 0.80*Structural(55) + 0.20*TournamentReliability(45) = 53; modifiers total -12 gives 41; Illegal-deck cap applied, final reported as 35 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core of 18 copies gives about 86% chance of at least one starter in the opening 5-card hand
• Nine hand traps and about eleven negation-text cards provide interaction on both going first and going second
• Extra Deck contains several high-ATK finishers (Dis Pater 3500, Majestic Star 4000, Psychic End Punisher 3500)

Weaknesses

• Illegal list: copy limits exceeded for Elfnote Lucina and Ash Blossom, and Extra Deck over the 15-card cap
• No Side Deck, so there is no adaptation plan for best-of-3 play
• Multiple competing engines (Elfnote, Junk, Synchron, Mulcharmy) reduce hand coherence

Critical choke points

• Elfnote starter on the center zone: removing it stops the Elfnote Synchro line
• Extra Deck legality: the list must drop at least 3 Extra Deck cards to be buildable

Recommended changes

Evidence & confidence

• Verified: Legality: Elfnote Lucina 3 copies vs 1 legal, Ash Blossom 3 vs 2, Extra Deck 18 vs 15 maximum; Archetype core: 18 copies; 86% chance of at least one in a 5-card hand; Card text for hand traps, negations and Synchro effects as listed in the evidence
• Observed: No combo boards recorded; nothing observed beyond card text
• Inferred: Starter reliability, brick risk and recursion routes based on card text and hypergeometric odds; Going-first and going-second estimates from interaction count and boss stats
• Provisional: Meta fit and matchup coverage: no dated metagame sample or tournament link; Tournament reliability: no per-pilot or win-rate telemetry
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchup, brick or OTK rates Meta Power is provisional: no dated metagame sample No Side Deck supplied
