very true... my original idea was that you had to remove a black card.. but that would kind of kill the... actuall i could just word it to still say "remove one card of the same color".. sweet... the original concept can stay!!
its slightly wordy in the reminder text...
but it reads
Target player discards a card.
Mirror 1 (You may reveal this card
and remove one card of the same color
in your hand from the game to put a
copy of this spell onto the stack.)
