Infinity Swarm

At the beginning of your upkeep and at the
beginning of your endstep, create a token copy
of Infinity Swarm.
A deck can have any number of cards named
Infinity Swarm.
"The swarm has been stopped. Where did they even
come from? They were suddenly just here but... OH
GOD! THEY'RE BACK!"
- Last words of an unknown man.
