Rulings
Hobgoblin Bandit Lord's activated ability only counts the number of Goblins that entered the battlefield this turn. It doesn't matter if those Goblins are still on the battlefield as it resolves.

If no Goblins have entered the battlefield this turn, no damage will be dealt. Abilities that trigger whenever damage is dealt won't trigger.
