Froghemoth

Graveyard hate usually reads as pure subtraction: you spend a card and some mana to shrink an opponent's yard and get nothing back but the deletion. This inverts that math by making the exile the payoff of an attack you were already committing to. Haste puts the body on offense immediately, and combat damage funds the exile, which in turn funds the counters and the lifegain. The interesting decision it forces is the split between creature and noncreature cards in the target's graveyard: creatures pump the Frog toward lethal, noncreatures stabilize you with life instead, so you are grading their yard on a curve while you swing. The ceiling is a snowball. Connect for four, exile four creatures, and it comes back an 8/8, doing hate, threat assessment, and clock in a single attack step. What pays for that value is the same thing that makes trample essential: the engine hinges entirely on damage reaching the player, so a removal spell in response to attackers or a bounce shuts it off, and unlike a static graveyard answer it does nothing while it sits. Trample keeps a chump block from stopping it cold; the blocker soaks its toughness, but the remainder tramples through and still fires the exile at reduced volume. It is a beater first that happens to eat graveyards, not a graveyard answer that happens to have a body, and the sequencing rewards you for treating it as the former.
