A Ratcipe for Disratster

Create a number of 1/1 black rat tokens with
menace and haste equal to half your life total,
rounded down. For each token that enters the
battlefield this way, you may choose to bombard
a target Location, or destroy target artifact or
enchantment.
"They say a great rat needs no enemies. I say we need
a few more." -Isperia, rat tactician
