Bela the Blessed

{3}: Exile another target creature you control,
then return it to the battlefield under its owner's
control.
Whenever another creature enters the battlefield
under your control, you may pay {g/w}. If you do,
put a +1/+1 counter on it. If it's a Unicorn, put
two +1/+1 counters on it instead.
"Strange as it seems, she may be the least weary
of all."
