Entropic Coils

Whenever a creature enters the battlefield or attacks, that creature's controller rolls a six-sided die, then applies the result:
1: Return that creature to its owner's hand.
2-3: Shuffle that creature into its owner's library.
4-5: Sacrifice that creature.
6: Exile that creature.
What's the fun in having perfect control?
