Banner of the Blue Phoenix

Banner of the Blue Phoenix enters play with 12
unit counters on it.
Legendary nonartifact creatures you control have
"{t}, Remove up to four unit counters from
Banner of the Blue Phoenix: create that many 1/1
Soldier creature tokens of one of this creature's
colors."
Whenever a Soldier you control is destroyed, add
a unit counter to Banner of the Blue Phoenix.
Twelve they are, yet only one purpose they serve.
Brothers in arms, scions of Blue Dragon.
