Played about 15 -20 matches last night with no variation , only lost 6 matches and 5 were against one player using ermac , variation didn't make a difference either because I kept making bad reads and kept letting him hit me with his ex teleport so that was really just bad playing on my part. Other than that It seems to help build fundamentals not having extra tools to use , found a decent really easy corner combo , b21 xx ex db1 242 f33 for 33%
