Can you tell me the rulings for Defiant Salvager?
user
0. If you sacrifice an artifact creature to activate Defiant Salvager's ability, you put one +1/+1 counter on Defiant Salvager, not two.
1. You can sacrifice Defiant Salvager to activate its own ability. It won't receive a counter, but abilities that trigger on the sacrifice or watch for a creature dying will see it.
