The Demon Child

Reveal this when your deity takes damage.
{3}: Create a 1/1 black imp creature token with flying.
When your deity loses the game, take two new 'satanic deity' cards, and pick one. You become that deity. (The satanic don't lose the game, but the previous deity still loses the game. You do not get the 'begin the game' effects, but you do get any other effects.)
