Required Balance

Choose one target creature you control and one
you don't control. They lose all their abilities,
then the power and toughness of each one
becomes the average of their power and
toughness, rounded down.
"The night is opposite to the day, but it is born from it,
and the day is opposite to the night, but is born from it. Neither can prevail the other, for they try to prevail,
and not seek the balance. What runs from balance,
creates balance."- Old Umarian saying.
