Tail Swipe

Fight has a built-in liability that green players learn early: it deals symmetrical damage, so springing an instant-speed ambush on an attacker usually means your blocker eats a return hit it can't walk away from. This design turns the buff into a reward for aggression rather than defense. Resolve the fight while your main phase is still open and the +1/+1 shows up, nudging your creature over a toughness breakpoint or letting a smaller body kill something larger. Hold the card back for the reactive window (flashed in combat, or during your opponent's turn) and the bonus vanishes, leaving your creature to fight without it. That timing clause prices flexibility against reliability, and it makes every cast a sequencing choice: take the pump now, or keep the ambush live for later? Prey Upon and the older green fight cards mostly locked one axis or the other, either fixing the timing or fixing the size. This one leaves both open and asks which matters more on a given board. The one-mana price makes that decision recur constantly, and it rewards a battlefield of creatures whose power lines up cleanly enough that the reactive line is worth taking.
