Caelid

{t} Add {r} to your mana pool.
If you or your opponent control 2 or
more creatures with scarlet rot Caelid
has: "{t} Add {r}{r} to your mana pool."
Caelid is marred by scarlet rot, mutating its flora and
fauna, bathing the environment in a deathly hue.
Death and decay are all too frequent sights here.
