untap one land that can produce a color in that
cards cost. Tap a land. You may untap a land.
Whenever you cast a spell, you may pay
{t}{u}{r}{g}. If you do, copy it. If it is a permanent,
it is not legendary. If you activate this ability,
you may pay {g/u}{u/r} any number of times.
For each time, copy that spell an additional time.
