Mogishath, Sun's Slaughter

Trample, vigilance, haste, indestructible
As long as your devotion to {b}{r}{g}{w} is less than
seven, Mogishath isn't a creature.
At the beginning of each player's upkeep,
Mogishath deals 7 damage to that player unless he sacrifices a creature.
Whenever Mogishath deals damage to a player,
exile that many cards from the top of your library.
Put any number of Dinosaur or God cards onto the battlefield.
