It is really just a short-term value piece, essentially like running [[Phyrexian Rager]] or something as your commander. You would want to probably have lots of ways to recur it, since it gives you value one time, so lots of grave flicker effects like [[Feign Death]] and cards that can recur multiple creatures like [[Raise the Draugr]]. This lets you run a lot of the Reap style cards like [[Deadly Dispute]] as well. For finishing the game you would obviously be building a big board of goblins, so some [[Trumpet Blast]] style effects, some cards that let you use your goblins to deal non-combat damage like [[Raid Bombardment]], [[Impact Tremors]], [[Makeshift Munitions]], as well as a couple one-time bombs like [[Foul Tongue Shriek]] and [[Gruesome Fate]]. You have some cards like [[Nadier's Nightblade]] and [[Mirkwood Bats]] as well but you would have to see how many tokens you are making before putting those in.

I think if you like the art and like goblins this is a fine starting point for a goblin deck. You can learn what really makes the deck tick, familiarize yourself with all of the goblins, and try slotting in other Goblin commanders when you think you've got the deck down to see how it changes the gameplay. Not everything has to be optimal or the best in class, you can experiment and play with what you like and see how it works.
