God-Eternal Oketra
3WW
Legendary Creature - Zombie God

Double strike

Whenever you cast a creature spell, create a 4/4 black Zombie Warrior creature token with vigilance.

When God-Eternal Oketra dies or is put into exile from the battlefield, you may put it into its owner's library third from the top.

My first thought was "overcosted for a humans deck." Then I started thinking about Modern bridge from below shenanigans with free creatures. Could this be cast and followed up with a bunch of 0 cost creatures like ballista, hangarback, and endless one? Hollow one and rootwalla, potentially, if you twist the build a bit (you already have riftstone portal for the white mana).

Maybe something like, play oketra, drop 3 0-drops for 3x 4/4 zombies? The 0-drops would have utility in themselves as you could drop them for X. I'm thinking an eldrazi-ish mana base with 2-mana lands to accelerate Oketra and bigger X-drops.

Just a thought.
