Swarm Shambler (PRM-83740) is a rare one-mana green Creature — Fungus Beast from the Magic Online Promos set. It enters with a +1/+1 counter, can be tapped and paid {1} to put another +1/+1 counter on itself, and creates a 1/1 green Insect token whenever an opponent’s spell targets any of your creatures that already have a +1/+1 counter. Its token-generation ability triggers once per targeting event and resolves before the targeting spell, and multiple targets or multiple counters on the same creature do not produce extra tokens.
