mogg fanatic used to be a 4-of in legacy goblins for dealing with other aggro decks.  I think it could fill a hole here.

perhaps tarfires should be mogg fanatics.  I think goblin lookouts and skirk drill sergeants will probably not be mvps, either.  But you could guess that by looking at the prices.  I hate to just be drawn inexorably into the exact same list as everyone else...

Goblin Recruiter is probably just a fantasy.  I'm imagining it leading to great ringleader draws, or fixing your topdecks for the rest of the game once you have enough mana.  I suppose it is really in there as a kind of sub for 8 fetchlands.  Since it's a goblin, it's not completely dead, but we'll have to see if it's better than drill sergeant and lookout when it comes time to make some changes.

some notes (albeit based on a true legacy deck that relies on vial/lackey/port/wasteland to be able to deploy threats while simultaneously disrupting manabases):

11/20/14 - okay, totally ditching the "legacy" vibe.  In kitchen table multiplayer, I'd rather see another goblin than an aether vial.  will dump those and strip mines.  Need to choose 4 more goblins, but may also need to remove a couple for purphoros...
