Dermor, Vordor's rival

When Dermor, Vordor's rival enters the battlefield, you may search your library for
two creature cards and put them on the battlefield. If one of those cards is called despair, Vordor's steed, you may mount it. It gains haste until the end of turn.
I will not have my peace until this war is over...
Or become the fifth lieutenant.
-Dermor
