Cemetery Mystic

Cemetery Mystic enters the battlefield with
a +1/+1 counter on it for each creature card
in your graveyard.
At the beginning of you upkeep, you may remove a +1/+1 counter from Cemetery
Mystic. If you do, return target creature card from your graveyard to the battlefield
tapped.
Each butterfly that accompanies her is a soul, yearning for a new beginning and another end.
