RoL/Hope is actually the only widely known FG farmer that hasn't changed much in any way since its release. This old version still works fine, though I prefer it with 5 Fractals. It was tested a while back in this thread:
http://elementscommunity.org/forum/index.php/topic,25609, and the only change that has affected it since then is that the AI prioritizes Rays even higher when Hope is up. Its winrate should still be around 45%, something my experience confirms as I use my own mod now and then.
Try it some more. You'll learn more and more tricks and your winrate will go up as you approach a bigger sample size. Also, I suggest trying decks in the
http://elementsthegame.com/trainer first before building them in the real game. You might run into an actual outdated deck, or just get some practice in that raises your winrate a lot. Some decks are like that (not this one).
