Synchron Deck #772518 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Blackwing and Synchron Synchro summons into large DARK bodies (Black-Winged Assault Dragon 3200 ATK, Blackwing Full Armor Master 3000 ATK, Chaos Angel 3500 ATK, Bystial Dis Pater 3500 ATK), with Blackwing Nothung adding 800 direct damage on Special Summon.; Mulcharmy hand-advantage draws and Pot of Sloth card advantage grinding the opponent out over several turns.
• Turn 1 (going first): Open with a Blackwing Tuner (Shamal, Vata, Sudri, or Assault Synchron) and a non-Tuner, Synchro into a Blackwing boss, while holding Ash Blossom, Infinite Impermanence, or Evenly Matched for the opponent's turn.
• Turn 2 (going second): Hold Ash Blossom, Dominus Impulse, Infinite Impermanence, Droll & Lock Bird, or Solemn Judgment to interrupt the opponent's first board, then rebuild with Mulcharmy draws and a Synchro boss.
• Recovery: Blackwing Zephyros and Chinook recursion from the GY, Black Feather Whirlwind re-summoning Blackwing monsters from the GY or banish zone, and Mulcharmy draws to refill the hand.
• After siding: Not evaluated: the deck has no Side Deck, so no post-side plan can be scored.

Why it scores here

The deck is scored as a system, not as an average of its cards. Its consistency is moderate: 12 searcher-text cards give about a 72% chance of at least one searcher in an opening 5-card hand, but only about 32% of hands contain one of the 4 archetype-core Mulcharmy/Droll cards, and 10 hand traps give about 71% of going-second hands at least one interaction. Its Synchro ceiling is high (Black-Winged Assault 3200, Full Armor 3000, Chaos Angel 3500, Bystial 3500), but no recorded combos exist, so the median and floor are inferred from text alone and kept low. Interaction (Ash, Dominus, Impermanence, Evenly Matched, Solemn, Droll) gives it real breadth, while the deck has no Side Deck and runs two cards over their OCG copy limit, so the score is capped as theoretical and structural-only. Popularity is not counted: archetype usage stats show only 2 core cards, and the score did not come from averaging card power.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy-limit violation (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; Illegal cap applied (theoretical/structural-only)

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 interaction suite: Ash Blossom, Dominus Impulse, Infinite Impermanence, Evenly Matched, Solemn Judgment, Droll & Lock Bird
• Ten Synchro bosses and three Link monsters give broad Extra Deck coverage
• Multiple Tuner options (Shamal, Vata, Sudri, Assault Synchron, Sharnga) increase Synchro access
• High ATK closing power from 3000+ ATK Synchro monsters

Weaknesses

• Illegal as built: two cards exceed their OCG copy limit
• No Side Deck for best-of-3
• Engine coherence is weak: only 2 of 72 cards are exact-name Synchron, and Blackwing, Mulcharmy, Cyclone, Dominus and Greed split the list
• No recorded combo data, so floor and median output are unverified
• Many dead-looking cards in hand (hand traps, draw cards) raise brick risk

Critical choke points

• Single-copy Tuners and Synchro bosses require specific Tuner plus non-Tuner combinations
• Two Semi-Limited interaction cards must be cut to legal copy counts before the list can be played
• Only 1 copy of Blackwing Zephyros, Chinook, Harmattan, Twin Shadow, and Garbage Lord

Recommended changes

Evidence & confidence

• Verified: Main Deck 56 cards, Extra Deck 15 cards, Side Deck 0 cards; Ash Blossom & Joyous Spring and Dominus Impulse each run 3 copies, OCG limit 2 (Semi-Limited); Solemn Judgment, Droll & Lock Bird, S:P Little Knight are Limited and run at 1 copy each (legal); Synchro boss ATK/DEF values from card data
• Inferred: Opening-hand hypergeometric estimates for starter, searcher, hand-trap, and archetype-core groups; Engine coherence reading from archetype spread (Blackwing, Mulcharmy, Cyclone, Dominus, Greed); Interaction breadth and going-second value from card text; Synchro closing power from ATK values and effect text
• Provisional: Meta Power and any matchup read; no dated metagame sample supplied
• 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 — brick, starter, going-first/second rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck supplied, so post-side plan is unscored Deck title is null, so the identity is taken from archetype only
