Mogg Fanatic is fine but there is a reason we don't run it anymore:
Goblins is 9/10 times forced to sit back and slowly build a wall. If you look at the meta-game when Fanatic was really good it was when the deck was functioning more like an aggro deck with Ringleaders to keep it coming. Now with the format being exempt from caring about most Lackeys, Fanatic confuses the deck's identity/purpose.
I love Fanatic more than anyone, and all the guys here know that. I even tried Ember Hauler in a MODO league once. They are unfortunately just a bit too weak. The last time I played Goblins I even played 4 Fanatic (probably 3 months ago) and they were as underwhelming for me as others have said above. They were however excellent in the Goblin Mirror lol.
If your metagame is 50% fair decks like Pyromancer Delver, Elves and DnT I would absolutely recommend playing maybe 2 Fanatics, definitely not 4 though. I played 2 Fanatics during the DTT days when every deck was basically cantrips + Pyromancer and it was a beating against those decks. I also agree that it is excellent against combo just because it has cmc1 not 48 like the rest of the cards in the deck. The
DCI foils look fantastic too :wink:
