Need some advice on my deck

Hi there, magic newbie here :) I created this standard mono red Goblin deck: https://moxfield.com/decks/5dLewQt8JEiotdlVfUfoIg. I already played this a couple of times. I’m now looking to get some advice since I want to bring this deck to a magic event: - will this deck insult people since the wincon is clearly to create an overload of goblin-tokens? - I see a lot of talk about the 4x9 strategy. Should I add more of the same creatures? Or replace some of the cards to make it more fun to play against?

Any suggestions would be helpful. Thanks.
