This deck is the best fg farmer I know of. I didn't create it, though; I think Sevs did.

Before 1.29, this was the best fg farmer. It's still pretty nice, but SoG took a bit of a hit.

The next best after those would be some sort of rainbow control; there's several different versions possible. I'd advise you to make your own, though; most of the rainbow control decks I've seen on the forum aren't as good as they could be.
The next 20 posts will probably tell you to play RoL/Hope. Don't listen.
edit: As for win rates, the first deck was reported to have something like 67-69% wins. The second had about 60% wins before SoG nerf, but that shouldn't change much. I have played both these decks, and while I haven't tabulated results for them, these are definitely in the ballpark for accuracy. The best rainbow control deck I've built can win about 50%, and I actually prefer it because it's more fun than the above two.
RoL/Hope has a piss-poor win %; I've seen claims that it wins somewhere in the 30s %, but I think that they aren't counting skips for bad matchups, because in my experience it's not really that high. Proponents of this deck claim that despite the skips, you can win a decent amount of upgraded cards/hour because you concentrate on pwning the few gods this deck does beat. That might well be true, but that kind of play style is not for me.
Instosis or SPlat probably.

Oh yeah, just to be clear, the Instosis that furball just mentioned is the first deck in my above post. I haven't ever tried SPlat for FGs, but it is good in the arena; this is the version I like best:

Use upped SoSas if you have them, obviously. I only have 1 upped and 5 unupped so far. (the blank cards)
well ive tried all sorts against FGs, and i seem to do best with this Hover over cards for details, click for permalink

i will sometimes alter it slightly, adding another SOG, taking out 3 precogs and adding 1 hourglass and an anubis and a twin universe, this is purely to make it more interesting for me.
i was asked why i use precogs and hourglasses, this is purely to combat explosions/steals allowing me 3 precogs to still rush the deck slightly, PLUS it shows opponents cards (as i use this deck in silver arena too) so i can get a tip on whether to save a shield or gotp, until they play a certain card.
p.s. i know this is ghostal, but the 1 above with 52 cards seems too many. i sometimes also lower my cardcount to 40. hope this helps :)
