Floating Scarecrow

If you paid life to cast Unhallowed Caster it gains a +1/+1 Counter, and Paid For In Blood (Whenever this creature deals damage, put a Blood Counter on it. You may remove two Blood Counters to pay for {1} of any Halloween type spell.)
If Blood Counters were used to cast Floating Scarecrow, it enters with an additional +1/+1 counter.
