Siege-Gang Commander , Goblin Recruiter , Goblin Sharpshooter (goes infinite if you add anything that gives deathtouch), and finally Goblin King all deserve mentions.

I try. Also, Gamble . If you find yourself playing V.S. a lot of tribal decks Door of Destinies may be better than Coat of Arms .

Goblin Warrens just because no one dislikes infinite goblins.

Eldrazi Monument or card:Akroma's Memorial + lots of tokens = death for your opponent

it won't hinder sacrifice because it does not target to sac a goblin unless it says target in the ability. This is a lot like my build so check it out and let me know what you think.

I love goblins, they're so much fun. I have a b/r goblins edh, Hot gobbos edh, using Wort, Boggart Auntie and I love playing it.. Some suggestions:

Goblin Recruiter + Goblin Ringleader is an awesome combo to find any goblins you want to put in your hand within 2 turns.

Sparksmith gets shit done if you don't mind kicking your own ass.

Goblin Tinkerer is amazing in edh, blows up any artifact and can get rid of some of the more annoying 1 or 0 drop artifacts (Sol Ring , Mana Crypt , Mana Vault , card:Sensei's Divining Top) without dying

Goblin Warchief is boss for hasty, cheaper goblins.

Urza's Incubator, Shared Animosity and Door of Destinies are amazing in any tribal deck
