The Phalanx of Grinscar

Haste, Banding
Whenever The Phalanx of Grinscar attacks,
bolster 1.
At the beggining of your upkeep, if you control
fewer than four phalanxes, create a 1/1 red and
green centaur phalanx token with haste, banding
and "Whenever this creature attacks, bolster 1".
Victory or death
