Ratchet Bomb

Create two 1/1 colorless Sliver creature tokens.

Islandwalk (This creature can't be blocked as long as defending player controls an Island.) Whenever this creature attacks, you may exile target creature defending player controls until this creature leaves the battlefield. (That creature returns under its owner's control.)

Sliver creatures you control get +3/+3.

Whenever this creature or another Human creature you control dies, create a tapped 2/2 black Zombie creature token.

T: Each creature attacks this turn if able.
