Whenever a Sith Lord attacks, you may have
its controller create a 1/1 white Storm Trooper creature token that’s tapped and attacking.

{2}{p/r}{p/r}{p/b}{p/b}: 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.
