Your Savior Is Here!

Create a player token with 20 life. That player takes each turn after yours. Choose a deck you
own from outside the game. That deck becomes that player's library. That player draws seven cards, and gets an emblem with "At the beginning of your untap step, choose another player at random. That player controls you until your next turn." You get an emblem with
"{6}: Exile target permanent you own and you
don't control." Exile Your Savior Is Here!
