Festerhide Boar

Morbid is the keyword that asks a creature to read the battlefield before it arrives, and this Boar is the cleanest reward for it. The default mode is a 3/3 trampler for four, a body that barely justifies its slot. But if a creature has died this turn (a chump blocker, a removal spell resolving, your own attacker traded away in combat), it walks in as a 5/5 with trample, a genuinely threatening size at that cost. Everything hinges on that conditional: it costs nothing extra to unlock, it just demands that you sequence your turn so a creature death lands first. That turns combat into a setup puzzle. Attack into a board where you can force a trade, or hold the Boar a turn until your own creatures start dying, and the same card swings between filler and one of the better green beaters of its era. The trample is what makes the upside matter; a 5/5 that gets chumped is far less frightening than one that pushes two damage through the blocker. As a piece of the morbid-era green toolkit, it sits between the small ground-pounders that wanted nothing from death and the explicit sacrifice payoffs that demanded a whole engine. The Boar asks for one death, a real creature dying, and pays out immediately.
