Dagger of the Dark Realms

As an additional cost to cast this spell, sacrifice a creature. Then, put a number of cinder counters
on Dagger of the Dark Realms equal to its mana
value.
Equipped creature gets +X/+X, where X is the
number of cinder counters on Dagger of the
Dark Realms. If Equipped creature is a Germ, it
gets twice +X/+X.
