Borofir, Boros Incarnate
Vigilance, haste, first strike
Whenever you attack with three or more creatures, creatures you control get +2/+1.
Eminence -- As long as Borofir is in the command zone or on the battlefield, white creatures you control have haste, red creatures you control have vigilance, white and red creatures you control have first strike, and creatures you control with the Boros signet on them cost {1}{r/w} less to cast.
Boros is more than an army.
