Andrew Solas, Unmasked

If an enchantment creature spell you control does not
have bestow, it gains bestow, but can only enchant
Andrew Solas, Unmasked. It's bestow cost is its
mana cost reduced by {2}
(If you cast this card for its bestow cost, it's an Aura
spell with enchant creature. It becomes a creature again
if it's not attached to a creature.)
When an enchantment creature spell is cast as an
Aura spell, the creature it enchants gains all of its keywords and all of its abilities.
