Sephiran, Nethysian

At the beginning of your upkeep, you may search
your library for a nonland permanent and put it
onto the battlefield tapped.
At the beginning of your end step, untap all permanents you control.
"Ambition has its limits. Bodies wither. Gods die.
Planes crumble. Even knowledge fades, in time...
For the life I've been given, I am."
