Kalis, Auraweaver

When Kalis, Auraweaver enters the battlefield, you may search your library for an Aura card, reveal it, and put it into your hand. Then shuffle your library.
Enchanted creatures you control have soulshatter. (Whenever a creature with soulshatter deals damage to another creature, that creature becomes a 2/2 morph creature with morph cost equal to its converted mana cost.)
