I would agree with that. When I got my MITB Goldberg proed I was running the table with him and a bunch of HD pros/Elite singles for a while. But now I'm at 17,000 points and my deck has started to catch up with that card, and the matches are harder... when I don't face a bot. Bots offer almost no resistance, and I seem to draw them quite often.
I play RR with a balanced 4-4-4-3 (LRDU) deck and I stick my best cards (of that direction) in there, but realistically I try to play primarily with my EL pros (Brock, KO, Orton, AA and AJ) and save Goldberg as my pocket ace for Match 10 or later.
And speaking of RR I just pulled EL Woods during my last game which will make another pro.
