Synchron Deck #769929 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Synchro boss monsters from the Extra Deck (Clear Wing Synchro Dragon line, Hi-Speedroid Kitedrake), but the Forbidden Extra Deck cards are not playable in this format; Hi-Speedroid and Clear Wing Synchro monsters converting Speedroid searches into Synchro Summons
• Turn 1 (going first): Open a Speedroid Tuner or searcher (Speedroid Terrortop, Speedroid Scratch) and Synchro into a boss; no combos were recorded, so the line is inferred from card text only
• Turn 2 (going second): Hand traps (Ash Blossom, Maxx C, Droll & Lock Bird, Crossout Designator) to interrupt the opponent's first line, then a Synchro boss; the 49% hand-trap-in-six-cards estimate is Inferred
• Recovery: Speedroid searchers and Speedroid Den-Den Daiko Duke (GY recursion) to rebuild Tuners; recovery depends on the Speedroid core being drawn, which is inferred
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The list is Illegal in OCG: three Forbidden cards are run (Auroradon, Crystal Wing, Baronne de Fleur), the Extra Deck holds 18 cards against a 15-card cap, and there is no Side Deck. Under the rubric it does not receive a normal final score, and the 25 is a structural-only read capped low. The deck spreads across at least six sub-archetypes (Roid, Clear Wing, Hi-Speedroid, Speedroid, Charmer, Dominus, Harpie), so exact-name archetype purity is 0%, which weakens engine coherence. The main-deck search and hand-trap package (9 searcher-text cards, 4 hand traps) gives some resilience, but with 10 single-copy slots and no combo boards recorded, consistency and combo output are Inferred from text only. This score was not produced by averaging card scores or by the popularity of the Synchron name; the Synchron archetype label and the guide's description of brick and instability were not credited.

Dimension scores

How the score was computed

Strategy profile: Balanced. Structural ≈ 44, Going First ≈ 42, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); extra-deck over limit (-8); illegal cap (-10). Final formula: Illegal list: 0.80*Structural(44) + 0.20*TournamentReliability(40) = 43, then modifiers (-10 banlist exposure, -8 extra-deck over limit), capped to a structural-only 25 per the Illegal rule; Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 hand-trap package (9 searcher-text, 4 hand traps) for consistency and interaction
• Clear Wing Over Synchro Dragon and Hi-Speedroid Kitedrake give high-ATK closing power
• Speedroid recursion (Den-Den Daiko Duke, Speedroid Scratch) supports rebuild after disruption

Weaknesses

• Illegal in OCG: three Forbidden cards and an 18-card Extra Deck over the 15-card cap
• No Side Deck, so there is no post-side plan
• Roughly six sub-archetypes with 0% exact-name purity, which weakens engine coherence
• Ten single-copy slots and many off-archetype cards raise brick and conflicting-starter risk

Critical choke points

• Speedroid Tuner availability: most Synchro lines need a Speedroid Tuner, and the Tuner count is small
• Forbidden Extra Deck cards cannot be played in this format, so the list must be rebuilt before any line works

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: three Forbidden cards and an 18-card Extra Deck over the 15-card OCG cap; No Side Deck (0 cards); Card text and stats for each distinct card; Guide snippet describes the deck as 'brick lòi và thiếu ổn định' (brick and instability)
• Inferred: Consistency and brick estimates from hypergeometric probabilities; Interaction quality from card text and role tags; Pilotability and combo complexity from card text
• Provisional: Meta Power (null, 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 are absent No win-rate telemetry for going-first, going-second, matchup or brick rates No Side Deck, so post-side performance cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
