Whenever a Warrior attacks, you may have its controller create a 1/1 white Warrior creature token that's tapped and attacking.
: Untap all attacking creatures. They gain
trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.),
lifelink (Damage dealt by the creature also causes its controller to gain that much life.), and
haste (This creature can attack, and as soon as it comes under your control.) until end of turn. After this phase, there is an additional combat phase. Activate only during combat.
