Hunter of Eyeblights
The trick is wiring its own setup into its own payoff. Most assassin-style removal bodies that destroy "a creature with a counter on it" need an outside source to mark a target first; this one hands an opponent's creature a +1/+1 counter the moment it enters, technically making the thing bigger while simultaneously stamping it for the tap ability. From then on the activation runs at instant speed for , fireable on anyone's turn at the moment of your choosing: an attacker mid-combat, a blocker before damage, a problem creature at end of step. The reach extends well past its own gift, too. Any creature already wearing a counter, from a planeswalker's incidental buff to a leftover marker from a previous combat trick to a persist or graft body, is legal prey. In an environment built around counters as a core mechanic, the pool of valid targets fills up without the Hunter lifting a finger, and the board the opponent built becomes the board the Hunter dismantles. The 3/3 for five is incidental; the value sits in converting a repeatable three-mana activation into open-ended, flexible removal that answers a different threat every turn. The only real friction is the awkward gift up front: you have to buff something before you can kill it, and a fast or evasive creature can punish you in the window between the counter landing and the tap going off.
