Aranyth Carnin, Strategist

Whenever a Warrior attacks, you may have its controller create a 1/1 white Warrior creature token that's tapped and attacking.

{w}{u}{b}{r}{g}: Untap all attacking creatures. They gain trample, lifelink, and haste until end of turn.
After this phase, there is an additional combat phase. Activate this ability only during combat.
