Can you play Dr. Sonny Jackson (times 3), then play Angry Mob and prevent all of the damage to yourself from the Angry Mob?
A 9.14 No. Dr. Sonny Jackson requires that, when played, you have damage ‘scheduled’ for your Ability Adjustment Phase. This means you may play DSJ in your Defense Phase IF your opponent played a damaging Event last turn. You may play it in your Defense Phase IF some “beginning of turn” effect (like Battlefield) has damaged you. You may play DSJ in your Attack Phase if your opponent played a successful attack that did damage to you. Damage from attacks is not “scheduled” until after the attack is determined to be successful which occurs at the end of your Defense Phase.
