Aura Animation

Create a 0/0 colorless Spark creature token
then attach target Aura you control to it.
If that Aura was a Crystal Aura, place two
+1/+1 counters on the Spark creature token.
"When the beast turned to solid crystal, I
assumed the fight over. However the true battle
begin, as its spirit took new life to attack me."
