Crown Of Lies

Eminence - At the beginning of your first upkeep,
if Crown of Lies is in the command zone or on
the battlefield, you become the monarch.
At the beginning of your upkeep, if you are the monarch, each opponent exiles the top card of
their library. You may play cards exiled this way without paying their mana costs for as long as
they remain exiled.
Crown of Lies can be your commander.
