Orion, The Emperor's Hand

Haste, Trample, Double Strike, Lifelink
(Orion can only be summoned if all council members are on the battlefield. If Orion is killed, exile him.)

Behest of his highness - Orion is immune to all flying creatures.
As the Emperor's most trusted subordinate and confidant, Orion commands near-supreme
authority on behalf of his liege.
