If Clavicus, Lord of Bargain is on the field, you
may ignore the text after each comma.
If you do, you lose life for each time you ignore it.
(When you ignore once, you lose 1 life, second would
be 2 life, 3 life and so on.)
While Barbas, Nagging Negotiator is on the field,
you can't lose the game. If you lose life greater
than your life total, you lose the game.
When Barbas, Nagging Negotiator takes damage,
you gain life equal to Barbas's
