Transcendent Ultimatum

Cast this spell only if there are five or more
colors among permanents you control.
Exile all monocolored permanents. Then, for
each multicolored permanent you control, you
gain 2 life, add 2 mana in any combination of
colors, and draw two cards.
Kept apart, the colours would inevitably fade. But
brought together, they produced beauty beyond
anything she had imagined.
