Invasive Fire Ants

First strike, trample
When Invasive Fire Ants attack, they get
+X/+0 until end of turn, where X is the
number of lands defending opponent controls.
Whenever a land enters the battlefield,
Invasive Fire Ants deal 1 damage to that
land's controller.
"The ants go one by one, but they all
carry sand" - Sidar Jabari
