Mirror of Adjustment

{4}{c} Select a creature you control or in your hand
and then swap the values of the card clockwise
meaning toughness values replace power values,
power values replace the mana cost value and the
mana cost value replace the toughness value.
After this cards ability is used twice any further
use will decrease the values swapped to
toughness and power by one and increase the
values swapped to mana by one.
