Most of the time I just keep a [mwcard=MW1I06]Dispel[/mwcard] prepared when I am expecting a [mwcard=FWE07]Mind Control[/mwcard] and I try to remove it the same round, thus if it is revealed the FM has spent a lot of mana (and so have I) to get rid of it and only have my critter stunned for the round. What is even more fun now, is I can Dispel the MC and then after I activate my creature (to remove the Stun) use my QC to cast a [mwcard=MWSTX2FFI06]Defend[/mwcard] on him.
I haven't got to try this yet with the Defend, but have frustrated many FM's trying to leverage Mind Control....Defend would just be a cherry on top.
