Controlling Mania

Shroud.
When Controlling Mania enters the battlefield,
put 3 stress counters on it. If Controlling Mania
has no stress counters on it, sacrifice it. At the
beginning of your end step, remove a stress
counter from Controlling Mania. Gain control
of target creature until controlling Mania leaves
the battlefield. Untap that creature.
It gains haste until end of turn.
I can sense your anger, let me help you release it.
