Part of what makes ELO fun is that it's constantly changing. If it wasn't, the nature of UR would mean that just a couple of decks and a particular playstyle would emerge as dominant, and that would be that.
Your deck isn't necessarily bad, but if you want to do well in ELO, go experiment with the new stuff.
As for Roots, they are still an amazing clan -- they just got rebalanced a bit. They gained many strong cards over the last year.
