How It Works
Activate Goblin Bombardment by sacrificing the additional creature.
When the creature dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
Resolve the Goblin Bombardment ability.
Activate Goblin Bombardment by sacrificing Sin.
When Sin dies, it triggers twice.
Resolve the first trigger, returning Sin from your graveyard to the battlefield with a -1/-1 counter on it
As Sin enters, remove the -1/-1 counter from the creature sacrificed in step 1, causing Sin to enter with a +1/+1 counter on it instead.
Resolve the second Sin trigger, putting the counters it had on it when it was sacrificed onto a creature you control and failing to shuffle it into your library as it's no longer in your graveyard.
Resolve the Goblin Bombardment ability from step 4.
Repeat.
