Custom Robo Arena-N00Bs' Night Out?

Okay, so if you didn't know already, i'm a MAJOR CRA fan. Tonight I've been playing a lot of games, and it seems like there's more n00bs and spammers on tonight than usual. I've lost about 5 times because I'm not very good at thinking up counters to spams on the spot. I really gotta work that out, lol...
