Chrisruptor

Indestructible.
When Chrisruptor enters the battlefield, he deals
5 damage to his controller. Whenever his
controller casts their second spell each turn, exile
Chrisruptor. Control of Chrisruptor shifts to the
player X places to the left, where X is the number
of spells cast after he is exiled in that turn. Return
him to the battlefield under that player's control
at the beginning of the next end step.
