Benalish Commander's power and toughness are each equal to the number of Soldiers you control.
Suspend X-. X can't be 0. (Rather than cast this card from your hand, you may pay and exile it with X time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
Whenever a time counter is removed from Benalish Commander while it's exiled, put a 1/1 white Soldier creature token onto the battlefield.
