Formal Agreement

At the beginning of your end step, each opponent
may decide whether or not they will attack you or permanents you control on their next turn.
Opponents who decide to attack you on their next
turn must do twenty pushups. Create a treasure
token for each opponent who decided not to attack
you on their next turn.

When a creepy jester comes knocking at your door and
hands you a deal, it's probably best to just take it.
