Phalanx Formation

All Soldier/Warrior creatures you control gain
First Strike, Indestructible.
If a non-token Soldier/Warrior creature is
removed from the battlefield, if you have a
Soldier/Warrior creature card in your hand,
put that card onto the battlefield.
If you do not, exile Phalanx Formation and
destroy all Soldier/Warrior cards you control.
"This is where we hold them! This is where we
fight! This is where they die!"
