Synchron Deck #771298 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon a large Extra Deck monster (Stardust Dragon, Red Dragon Archfiend, Colossal Fighter, Dark End Dragon) and protect the board with the trap and spell suite. The deck has almost no Tuner access in the Main Deck, so this plan is rarely reachable.; Infernity and Destiny HERO recursion (Infernity Archfiend, Destiny HERO - Malicious) feeding a Tuner-less Synchro line, or Brain Control / Mind Control stealing a board.
• Turn 1 (going first): Open a starter (Dark Grepher, Infernity Necromancer, or Infernity Archfiend) and try to reach a Tuner. Only Plaguespreader Zombie is a Tuner in the Main Deck, and it must first be in the GY. Most openings will have no Synchro route on turn 1-2.
• Turn 2 (going second): Use Bottomless Trap Hole, Mirror Force, Torrential Tribute, Dimensional Prison, Solemn Judgment, or Heavy Storm to disrupt the opponent's board, then rebuild from the GY. Synchro conversion stays unreliable, so the interaction carries the plan.
• Recovery: Recover with Burial from a Different Dimension, Foolish Burial, Destiny HERO - Malicious, and Plaguespreader Zombie from the GY. Recovery restores hand resources but does not reliably restore a Synchro engine.
• After siding: Not evaluable: the deck has no Side Deck (0 cards), so no post-side plan exists.

Why it scores here

The deck is scored as a system, not as an average of its card scores. It is named Synchron, but it runs no Synchron cards, and it has only one Tuner in the Main Deck (Plaguespreader Zombie, which can only be summoned from the GY). With 14 Synchro monsters in the Extra Deck, that leaves the Synchro engine rarely reachable on T1-T2, so D1 and D3 are held down. Interaction is the deck's real strength: several traps and spells (Bottomless Trap Hole, Mirror Force, Torrential Tribute, Dimensional Prison, Solemn Judgment, Heavy Storm, Dust Tornado) give it a broad removal and negation suite, which lifts D7 and makes the going-second case more credible. The deck is illegal, since it runs two Forbidden cards (Giant Trunade and Return from the Different Dimension), so it is capped low and labeled structural-only. Its popularity, the guide's remarks, and the archetype label earned no points; no usage-stat core cards are present, and there are no recorded boards or meta data.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; Midrange secondary, disclosed but not weighted separately. Structural ≈ 31.6, Going First ≈ 25, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 20. Modifiers: banlist exposure (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); then Illegal cap applied (-4 banlist modifier): 0.80*31.6 + 0.20*20 = 29.3 -> 25

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Broad removal and negation suite (29 removal-text, 7 negation-text cards)
• Multiple recursion routes from the GY (Burial from a Different Dimension, Foolish Burial, Destiny HERO - Malicious, Plaguespreader Zombie)

Weaknesses

• Illegal: two Forbidden cards in the Main Deck
• No Synchron cards despite the Synchron label; only 1 Tuner in the Main Deck for 14 Synchros
• 41 spells/traps among 55 Main Deck cards, so monster density is very low
• No Side Deck
• No recorded combos or win-rate data

Critical choke points

• Tuner access: the only Main Deck Tuner (Plaguespreader Zombie) requires GY placement before it can be Special Summoned
• Forbidden-card legality: the list cannot be played in OCG until both Forbidden cards are removed

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: Giant Trunade and Return from the Different Dimension are Forbidden in OCG; Main 55 / Extra 15 / Side 0 are within the OCG size rules; Only 1 Tuner Monster in the Main Deck (Plaguespreader Zombie); No Synchron-named cards in the list (exact_name_purity_pct 0); Usage core cards (Mulcharmy Fuwalos, Droll & Lock Bird) are absent
• Inferred: Synchro engine access on T1-T2 is low given Tuner count; Brick rate is high given 41 level-0 spells/traps in the Main Deck; Interaction density supports going-second strength (text-based)
• Provisional: Meta Power and matchup fit (D13) need a dated metagame sample
• Data gaps: no combos supplied: floor, median, and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick, starter rates) Meta Power is Provisional unless a dated metagame sample is supplied
