Is the Battle Institute a good judge at how you are going to do against real people in The Battle Center? I know this might sound like a stupid question, but I really don't like to lose (not that I would turn my game off, I am not a bad sport, at least not against humans), and I just want to know how badly I will get my rear handed to me. I do really well against two or three teams then one team comes along and roflstomps me.
My FC is 2938-7363-0108

Yes and no. Some level of skill is required to do well in the Battle Institute/Maison, so if you're getting your ass handed to you in the BI/BM, you probably won't do well against most most competent human opponents. However, real people behave somewhat differently than the AI, and the BI/BM sometimes uses really bizzare sets (like a physical Gengar or an Alakazam that spams Guard Split). There's also Mega Evolutions to take into account; BI/BM doesn't ever use them, but they're a common sight in the Battle Spot.
Does this help? Also, if you need help with team building or strategizing or whatever, feel free to ask more questions here.
