Bountiful Wellspring

When Bountiful Wellspring enters the battlefield
add {c} to your mana pool.
At the beginning of your precombat mainphase add
one mana of any colour to your mana pool.
Wherever nature is allowed to be in harmony with
itself all colours of mana flourish. Only skilled magicusers can draw specific colours of mana from
the wellspring, when the powers of nature manifest
in a burst of pure power.
