Ixion, Lightning of Djose

First strike, aeon (When Ixion enters the battlefield, tap an untapped summoner creature you control. You may choose not to untap it during your untap step. When it becomes untapped or you don't control a summoner tapped with Ixion, shuffle Ixion into its owners library.)
Whenever Ixion deals combat damage to a creature, destroy all auras attached to that creature.
{2}{w}: Ixion gains protection from the color of your choice until end of turn.
