Charge of the Fearless Few

Tap 3 creatures. Those creatures get +5/+5. Sacrifice those creatures at the end of combat.
Into the fray goes the brave and the bold. Knowing
death will take its hold. Fearless, resolute, they know
no fear. Their time will come when the end is near.
Glory be to the fearless few, to whom true courage
they only knew. Let them go, and chase the sun.
Knowing to only them, the battle's won.
