You attack. Stuff dies. The Goblin Sharpshooter and Stuffy Doll both trigger. The triggers go on the stack in APNAP order, so the Stuffy Doll trigger is on top of the Sharpshooter triggers and will resolve first.
so this means i die before i can use sharpshooter? I think i got it. I'll have to look more into APNAP order. That's a little foggy for me.
