BOB

As BOB enters the battlefield, choose a player to
become your Host. (You have one Host at a time.)
At the beginning of your upkeep, your Host may
pay 3 life or sacrifice a creature. If they don't,
you control that player during their next turn.
End the turn.
Whenever your Host draws a card, you draw 2
cards and may put a land card from your hand
onto the battlefield.
