Infinite Infestation

Whenever an opponent gets a poison counter you
may pay {2} if you do create a Mite token.
Whenever two or more mites you control die
create a Mite token.
Sacrifice three mites: If Infinite Infestation is in
exile, put it into its owner's graveyard. If it's in
your graveyard return it to your hand. If it's in
your hand put it onto the battlefield.
