the rulings on gravedigger say:
A "creature card" is any card with the type Creature, even if it has other types such as Artifact, Enchantment, or Land. Older cards of type Summon are also Creature cards.
so i know that artifact can be artifact creature and land can be manland creature, but I dont see how enchantment can be a creature? or does this mean I can get a enchant creature card like alexi's cloak?
