Irrational Mindsoul Core

At the end of your turn, if the number of cards
in your library and graveyard are equal, Irrational
Mindsoul Core deals damage equal to the
number of cards in both to each opponent.
Inequality is the root of many evils, would you not
agree? Let us seek equality in all things; those that fall
low will be lifted up, and those that would dare to fly
shall be brought low from their lofty perches.
