Ravenous Slime

Most graveyard hate answers the graveyard after the fact: exile a card, disrupt a loop, shut off recursion once the yard is already stocked. This Ooze does the work upstream, intercepting opposing creatures at the moment they would die and exiling them before they ever touch a graveyard. That single redirection defines what it does. A deck built to loop dead creatures, reanimate a fatty, or trigger a death-payoff finds the fuel simply gone, and the Ooze grows on every conversion it makes. The +1/+1 counters scale to the exiled creature's power, so the more threatening the thing that dies, the faster this becomes a real body: a graveyard-denial engine that also happens to be a clock. The evasion clause pulls its weight too, since a swelling Ooze that can't be chumped by anything with power 2 or less turns each opposing death into pressure that opponents cannot easily wall off. It is a rare piece of hate that punishes the opponent for the very interaction it is shutting down, converting their removal and their sacrifice fodder into your win condition rather than merely denying them value. The starting 1/1 frame is the honest tax: it does nothing until an opposing creature dies, and against a board that refuses to trade, it stays small.
