I use FC1B a lot, and if for some ungodly reason Mina ends up close to Ivy, I mix 1B,B // 4A (but mostly 1B,B) and if the other player is not too into the match, I sometimes use 9A+B, then G, which if the Ivy player goes into a "ZOMG fire attack!!" state for a second before he tries to punish you, lands you someplace far from her.
Oh, and if you're side stepping, I recommend trying 4A,A once in a while, it seems to work for me.
I only play offline however (hence it's easier for me to see if the other guy is too into the match or not). I hope I'm able to at least play a few matches online to know the online level. I believe my Mina will get her rear end slashed back and forth. Not that I expect to win always -or half the battles for that matter- while trying to fully learn Mina.
