John Kramer, Jigsaw

When John Kramer enters, and on your end step each turn, choose a rule:

- Your opponents cannot cast more than 2 spells in a turn.
- Your opponents cannot cast spells on other players turns.
- Each opponent must sacrifice a creature during their upkeep.

Only one rule may be in place at a time.

If a player breaks the current rule, they lose 2 life and you create a blood token.
