I was talking to the Archmage folks and they noted that the Archmage bot has the most success in the higher leagues, which I thought was interesting. Regarding earnings, I was able to make leaderboard with the xbot, and Archmage was close. So, it you figure in all the costs, I was close to break even, or even net positive by a little with Daily and EOS chests. Really I think if you just use the best cards you can make a little with leaderboard earnings, otherwise you probably lose a little.
