The Ceaseless Void

This creature isnt a creature unless your devotion to blue and black are both 3
The Ceaseless void has Indestructible, Hexproof, and Protection from everything as long as an energy orb creature token is in play
When The Ceaseless void enters create four 3/3 energy orb creature tokens with "this creature must attack each combat if able"
If ceaseless void would would ever leave the battlefield return it to the battlefield under your control. This can only happen 3 times a game
