Casper the Menace

Trample, Deathtouch
Whenever Casper the Menace becomes the
target of a spell or ability, Casper gets +0/+3
until the end of turn.
When Casper the Menace leaves the battlefield,
you may destroy a target permanent.
He may look like just a big bababooie, but he
revels in the thrill of the chase and delights in
leaving a trail of mangled bodies in his wake.
