Hell Mongrel

A discard cost and a discard-triggered escape hatch, sold together: the 4/3 body pumps itself by pitching cards, and pitching this very card is how you land it from exile at a discount rather than paying full price out of hand. Both functions run through the same resource. Any effect that asks you to empty your grip becomes a way to drop this cheaply onto the battlefield and, once it has stuck, feed its own growth, while the cards you shed are usually ones you were happy to see in the yard anyway. It descends from a long line of red-black hellbent and reanimator-adjacent creatures where the discard clause reads as a payoff dressed up as a cost. The catch is that the pump is not free: every activation spends a whole card for one point in each direction, so the ability suits a deck already stocked with dead or recursive cards and quietly bleeds one trying to hold a full grip. Draw it with nothing left to pitch and it is simply a 4/3, which is the honest floor of most beatdown-slanted madness bodies: the reward tracks how badly the rest of the deck wanted to be discarding to begin with.
