Swarm of Oblivion

Flying
When Swarm of Oblivion enters the battlefield create X 1/1 green Insect creature tokens with "at the beginning of your upkeep, create a token thats a copy of this creature."
Other insect creatures you control get +1/+1 for each insect creature you control.

War, plague... Anything but that dreaded buzz."
