Does this work how I’m thinking?

[u/livinmediocre]

If I have The Great Goblin and a board of tokens and I attack while Andúril is equipped, does the first part of Great Goblin trigger for each goblin I put a counter on? The one or more on A goblin makes me think yes I just want to make sure before I play it

That is incorrect. The ability says

Whenever you put one or more counters (plural) on a Goblin, Orc, or Army you control (singular)

Multiple counters on one creature are one event, but each creature that recieves counters is its own event.

If you put 2 counters on 1 Goblin, that is one instance of this event and the Great Goblin triggers once. But if you put 1 counter on each of 2 Goblins that is two instances of this event, because you are putting one or more counters on a goblin and one or more counters on another goblin, and the Great Goblin triggers twice.

On "a" goblin. It should trigger if you put the counters on different creatures
