Kodlak, Troubled Harbinger

{t}, Tap three untapped creatures you control:
Exile target creature you don't control. If Kodlak
is a Werewolf, he loses that creature type and
cannot transform.
When Kodlak dies, if it isn't a Werewolf, create a
4/4 white Spirit Companion creature token with flying.
At the beginning of your end step, you may
transform Kodlak.
