FORCING AN ACTOR TO ENTER A STATE RATHER THAN GUARD IN RMXP

I can't figure out a way to do this for the life of me.
As the title implies, I need script to make the "guard" command switch the user between a higher attack and higher defense form using a state.
So 1st use = attack form, second use = defense form, thrid use = attack form, etc.

I want to do this because I also have a script in the works that restores MP based on damge taken. so entering high attack mode recharges your MP faster.
