Brontotherium

Pairing trample with provoke turns a green beater into something close to targeted removal that also pushes damage: the keyword reaches out and yanks an untapped blocker into a fight, and whatever toughness that blocker can't absorb spills over into the defending player. Most provoke creatures are content to drag a chump out of position; this one is built to delete the blocker and still connect. The 5/3 frame is where the design pays for that power. Three toughness means the beast survives only the fights it picks against the smallest creatures: provoke anything with three or more power and the attacker dies in the same exchange. That fragility is the leash on an ability that otherwise lets the aggressor name its matchup, and it keeps the card from reading as clean removal stapled to a body. You choose the block, but you are usually trading. The flavor sits flush with the math: a charging beast singles out a smaller defender, runs it over, and carries through whatever the body can't stop. It lives in the corner of green's design space where evasion and creature removal blur together, getting damage in by erasing the blocker rather than going around it.
