Shadow the City-Crusher

Trample, Menace (this creature is a menace)
{t}: Shadow knocks the battlefield onto the floor.
All players take turns picking up the spilled cards.
Play resumes with whatever creatures you pick up.
When the Poke Flute is played, Shadow the City-Crusher wakes from his slumber and crushes
your city. Really, you should have guessed that.
"Oh Lawd, he comin' "
