Balance in the Afterlife

At the beginning of each players upkeep, if that
player has less creature cards in their graveyard
than any other player, they sacrifice a creature.
{t}, Sacrifice Balance in the Afterlife: Each player
exiles all creature cards in their graveyard. For
each card a player exiles this way, that player
draws a card. Activate this ability only if all
players have the same amount of creature cards
in their graveyard.
