Ceasair, God of Misfortune

Indestructible
As long as your devotion to red, blue and black
is less than seven, Ceasair isn't a creature.

Whenever Ceasair enters the battlefield and
any time a creature blocks one of your
creatures, each player reveals the top card of
their library. Every player randomly discards a number of cards from their hand equal to the
lowest total mana cost revealed.
