Blooming Stinger

Deathtouch is usually a defensive keyword, a way for a small body to trade up and discourage attacks; this design turns it into a proactive tool. The creature carries deathtouch itself, but the entry trigger hands the keyword to a second creature you already control for the turn, which is where the interesting math lives. Deathtouch pairs with anything that spreads damage: a creature with trample now punches through the smallest possible blocker for lethal, a first-striker kills before it can be killed, and a fight or ping effect trades one instance of damage for a whole creature. The trigger fires on entry, so the window is fixed to the turn it arrives, but the body it lands on doesn't have to be the new one: point it at your best attacker and the value scales with what you already have on board. That is the quiet efficiency here. A vanilla-adjacent two-power body with deathtouch is a reasonable roadblock, and the enters trigger converts it into a green combat-math enabler that rewards a battlefield already built to hit hard. It asks for a follow-through the way most green two-drops don't, giving the color a small dose of the removal-by-combat that it otherwise has to earn through fights and bites.
