Legendary Creature - Zombie God
You may reveal the first card you draw each turn as you draw it. Whenever you reveal an instant or sorcery card this way, copy that card and you may cast the copy. That copy costs 2 less to cast.
When God-Eternal Kefnet dies or is put into exile from the battlefield, you may put it into it's owner's library third from the top.
This seems kind of strong to me. It's the price of Jace, but is a 4/5 flier and lets you copy any instant/sorcery off the top. Upkeep, mystical tutor for ancestral? Walk? Gifts? Costs 2 less for the copy too. Seems good.
