Angelic Armour

You may pay {2} instead of {w}, {r}, or {b}
(pay for each)
Creatures you control have haste.
Whenever 3 or more players take combat damage
in a turn exile Angelic Armour and transform it
into Zerachiel, Bringer of War at the beginning
of your upkeep.
"It has been a while since I last wore this armour..."
