Eviscerate
Eviscerate is an uncommon Silent attack that costs 3 Energy base and deals 7 damage three times (21 total), but its cost decreases by 1 for each card discarded this turn. With two discards, it costs 1 Energy; with three or more, it becomes free. This makes it one of the highest-damage cards in the Silent's arsenal when the discard condition is consistently met, turning it into an efficient triple-hit attack.
Eviscerate is a cornerstone of discard-focused builds. Paired with Acrobatics, Prepared, Calculated Gamble, or Tactician, it can frequently reach 0 or 1 Energy cost while delivering massive damage. Multiple copies further reward the discard playstyle. Upgraded, the base damage per hit increases to 9 (27 total at full cost), which is already strong, but the real value is that upgraded copies are even more punishing when discards reduce the cost. A top-tier win condition for discard-centric Silent decks.
