Warpstorm Elemental

Chaoswave (When you cast this spell, roll on the Chaoswave table.)
When Warpstorm Elemental enters the battlefield, choose another target creature.
Create a 1/1 copy of that creature. The copy
gains haste and has the ability: "At the beginning
of the next end step, exile this creature."
"The elemental ripples through the fabric of reality, it distorts and replicates."
