Tandem Takedown

Green's removal has always come with a bill. The color's cheapest way to kill something is to point a creature at it, and the historical price of that access is the return blow: Prey Upon makes your creature and its target trade damage both ways, so you buy the kill by risking your own body. This design pays the tax differently. The damage is one-directional, so your attackers take nothing back, and it lets up to two of your creatures pile their power onto a single enemy target, which turns a board of individually-too-small bodies into enough combined damage to finally push through something with real toughness. The "up to" clause keeps the spell live even with a lone creature: one attacker still swings a full one-way bite plus a +1/+0 boost, so a thin board sacrifices explosiveness rather than function. That rider is quiet but load-bearing: it tips a specific toughness threshold and swings combat math when the spell is held as a trick. The genuinely unusual part sits beneath the damage math: the target can be a creature, a planeswalker, or a battle, which lets green do something it almost never manages at instant speed, cracking a battle or knocking a planeswalker off the board without committing to a combat step. The lineage it descends from is the fight-and-bite spell; what it inherits is the removal, and what it discards is the counterpunch.
