There's
this, but I don't see how that's very helpful...
I only discovered a local Legacy GPT when a friend of mine sent me an email notice of it.
But I'm still not sure what to play.

Either some kind of Fish deck (metagamed against Goblins) or 3cThreshold. Or I might just say fuck it and play Affinity or Sligh instead. I don't own any of the cards that go into Goblins, except for Vials and Jittes*.
