Azafina, Bastion of Hope

+1: Give all humans vigilance. Humans who already have a vigilance counter will instead get +1/+1.
-2: Until your next turn, all creatures you control gain 'Ward- {1}' Azafina is also untargettable by attacking creatures.
-6: Until the end of your turn, if a nonland permanent would die, you may sacrifice Azafina instead to protect it. She returns to your hand.
