Juliana, Seraph of Order

Flying, Vigilance, Trample, First Strike
Sovereign-- As long as Juliana, Seraph of Order has flying, creatures you control have flying. The same is true for vigilance, trample, first strike, double strike, lifelink, deathtouch, haste, hexproof, shroud, and reach. (All creatures with Sovereign in your deck must share a name.)
At the beginning of each upkeep, if no creatures attacked last turn, you gain 5 life.
