Lyx, Undead Enchantress

{2}{t}, Creature cards in your graveyard gains disturb until end of turn. The disturb cost is equal to its mana cost. When you cast a creature with disturb this way, you may exile it, and have it become an Enchantment Aura attached to target creature you control. If you do, it loses all other card types, that gains the effect "Enchanted creature has all abilities of this creature card."
