Krallenhorde Shaman

When this creature transforms into Krallenhorde Shaman, you may exile target Wolf or Werewolf creature from your graveyard. If you do, create a
X/X green Wolf Spirit creature token where X
is the mana cost of the exiled creature.
At the beginning of each upkeep, if a player cast
two or more spells last turn, transform
Krallenhorde Shaman.
