Why on earth are deck creators making such outrageous claims of their decks' competence? Just how many times I've seen some deck with no upped cards labeled "FG farmer". Excuse me? 'Farming' is monotonous repetition of easy steps to achieve some goal associated with winning. If the deck needs to get some really lucky draw on both your hand and FG's hand in order to win, it's no farming. If the deck loses nine times out of ten, you're not gaining money there. You're losing it. Stop saying deck is made for farming when it obviously isn't capable of it. ![Angry >:(](https://elementscommunity.org/forum/Smileys/solosmileys/angry.gif)
"I tried it once in trainer and won."
If you lose to FGs 9 times out of 10, you
are making money due to card drops. Nine losses costs you 270 gold, and even the least lucrative FGs have an expected payout of 450+ gold after card sales. And if you're using an unupped deck with a low winrate, you're probably picking fights against the most easily exploited FGs, those with one-dimensional decks that are easier to get cards from, so you're earning more like 600 gold per win on average. That means you're earning at least 300 or so gold every 10 games in the long run, and since you're probably forfeiting outright against most gods you're getting through 10 games in maybe a little over 10 minutes. Your 10% winrate farmer can still easily pull 1000+ gold per hour. Not great, but not terrible.
You are, of course, going to absolutely murder your score and W/L record. It doesn't take too long to earn enough money to get some upgrades and stop hemorrhaging score, but if you care strongly about your record you should probably stick to farming AI3 until you get enough money for a better deck with some upgrades. You're going to need a fat bankroll
anyhow, since a 10% winrate deck is very vulnerable to streaks; sometimes you'll get 5 cards in 20 minutes, sometimes you'll burn through a couple thousand gold worth of losses in between card drops.
