Most exploit creatures pay you in cards, tokens, or drain: sacrifice a body, get something tangible back. This one converts the sacrifice into pure tempo aimed across the table. The creature you exploit is your own, but the target its trigger hits does not have to be, so the reward is a soft tuck. Crucially, the owner (not you) picks top or bottom of the library, and that single concession is what stops a five-mana defensive body from buying a hard answer for the price of a spare token. Bottom would exile a threat from the game in all but name; top hands it right back on the next draw. So the effect is a stall, not a kill: you strip a blocker for a swing, or bounce a problem out of the way for a turn, and the opponent decides how much time they lose. That timing window is the whole transaction, and it pairs naturally with an exploit cost you were already glad to spend (a creature with its own death trigger, a chump you kept back, a token). The 3/5 is deliberately a wall rather than a clock: this trades a creature to buy a turn and a durable frame to hide behind, not to pressure life totals. It sits in the blue tuck lineage, in the family of effects that answer a threat by relocating it rather than destroying it, an axis blue has always preferred to outright removal.
