Koeus, Farwatcher

Eminence - At the beginning of your end step
exile the top card of your library if Koeus is in
the command zone or on the battlefield. Until
the end of your next turn, you may play that card.
Whenever you play a card from exile, it enters
the battlefield with three +1/+1 counters on it if
it was a creature, Koeus deals 3 damage to any
target if it was an instant or sorcery, and you gain
3 life if it was a land.
