Blessing of the Warrior

This spell costs {4} less to cast if your devotion to white, black, and red is equal or more than seven.
Creatures you control have haste, vigilance, and
first strike.
Whenever a creature enters the battlefield under
your control, it fights target creature you don't
control.
"My gift is a thirst for battle that can never be
quenched, and the courage to try to anyway."
