Ladugar, Betrayer of Mardu

Menace, Haste
Whenever another nontoken creature you control
dies, flip a coin. If you win the flip, return it to
the battlefeild under your control. If you lose the
flip, exile it under an opponents control with a
dread counter on it. As long as it is exiled in this
way, that opponent may cast it, and they may
spend mana as though it was any color to do so.
Do not rejoice to soon.
