Ant Marauder

When Ant Marauder enters the battlefield, put
X -1/-1 counters on target creature an opponent controls, where X is the number of Ant creatures
you control.
Ant marauders excel when working in large groups,
using powerful bites and stings to take down prey
much bigger than themselves. On Hajira, ant
marauders defend the Formican Empires from threats
while expanding ever-deeper into the southern jungles.
