Synchro Cracker — Power Evaluation

Final Score: 49 ± 6 · Confidence: Medium

  • Intrinsic: 50 · Deck: 47 · Meta: provisional
  • Primary role: Board breaker / Going-second · Secondary: Removal

Why it scores here

Synchro Cracker is a generic going-second removal spell, but it only functions when you already control a Synchro Monster, so it is never a starter and does nothing on its own. Its payoff — non-targeting destruction of every face-up opponent monster with ATK at or below the returned Synchro's original ATK — can be a real board wipe, and returning the Synchro to the Extra Deck keeps it reusable. Walls of monsters with higher ATK, face-down monsters, and backrow all survive, so the card converts pre-existing setup into removal rather than into a resilient win. Its ATK-based ceiling earns no points by itself; only the text's genericity and the Extra Deck return do.

Axis scores

Axis Score Evidence
Accessibility 32 The card text requires a Synchro Monster you control before it is live and no searcher appears in the evidence, so it is a conditional card played at ~1.6 copies (verified card text + observed decks).
Combo & Conversion 25 It builds no board and appears in 0 recorded combos, only converting an already-established Synchro into removal (observed, no combos supplied).
Resource Economy 45 It trades your Synchro (returned to the Extra Deck, not the GY) for the opponent's monsters, roughly even-to-positive on board but offering no refuel (inferred).
Effect & Interaction 56 It provides non-targeting mass destruction of opponent's face-up monsters with ATK ≤ the returned Synchro's original ATK, but ignores backrow, face-downs, and higher-ATK monsters (verified card text).
Material Utility 5 It is a Normal Spell with no body, Level, or Attribute to contribute as material (verified card text).
Resilience & Flexibility 38 Returning the target to the Extra Deck keeps it re-summonable, but the card is a one-shot that needs a Synchro to have survived and offers no GY value (inferred).
Deck-Building Efficiency 55 No locks, no garnets, and 1–3 copies across 23 decks (avg 1.61) make it a fairly cheap slot in Synchro decks (observed decks).

Calculation

Weight profile: 0.7 Board breaker / Going-second + 0.3 Removal. Intrinsic ≈ 50, Deck ≈ 47, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Fully generic text: works with any Synchro Monster you control
  • Non-targeting destruction of the opponent's face-up monsters (only your own Synchro is targeted)
  • Returning the Synchro to the Extra Deck lets it be re-summoned later
  • High ceiling: returning a high-ATK Synchro can wipe a wide board
  • Cheap to run — no locks, no garnets, ~1-2 copies

Weaknesses

  • Dead in hand unless you already control a Synchro Monster
  • Does nothing on its own — never a starter or combo piece
  • Misses face-down monsters and all backrow
  • Fails to destroy monsters whose ATK exceeds the returned Synchro's original ATK
  • Competes with stronger, more flexible going-second tools like Forbidden Droplet

Counters / choke points

  • Spell/Trap negation such as Solemn Judgment or anti-Spell floodgates
  • Removing or negating the Synchro Monster before this resolves leaves it dead
  • Monsters with ATK above the returned Synchro's original ATK
  • Face-down monsters are unaffected
  • Monsters that cannot be destroyed by card effects

Best use

Going-second board-breaking removal after establishing a Synchro. Decks: Swordsoul, Speedroid, Synchron, T.G., Rose Dragon. Suggested copies: 1.

Evidence & gaps

  • Verified: Card text: target 1 Synchro Monster you control; return it to the Extra Deck, then destroy all face-up opponent monsters with ATK ≤ that Synchro's original ATK; Type is Normal Spell; ATK/DEF are 0 since it has no body; Legal in TCG, OCG, Master Duel, and Duel Links
  • Observed: 23 decks run it, all in the main deck, averaging 1.61 copies (15 at 1, 2 at 2, 6 at 3); 13 distinct archetypes, led by Swordsoul (21.7%) and Speedroid (13%); 0 recorded combo appearances — no starter role, material role, or payoff role data; 0 guides mention the card; Not a top card in any format ranking
  • Inferred: Because it demands a Synchro Monster already on board, it is a going-second removal card rather than a starter; Returning the Synchro to the Extra Deck rather than the GY preserves it for re-summoning; The ATK-threshold condition makes the card's quality scale with which Synchro you return
  • Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
