Soulowl Deathknight

You may play Soulowl Deathknight from your graveyard, but not anywhere else.

Soulowl Deathknight's power is equal to your devotion to colorless.

Once per turn, exile a creature card from a graveyard, put
a 3/3 colorless Soulowl creature token with flying on the field under your control. If you can't, sacrifice this card.

If this card would be removed from the battlefield, sacrifice all creature tokens you control.
