Does Mind Trick create an opening to flip your stance card? The other similar abilities that have been in question are all reactions to the attack itself, while this isn't. Your second attack isn't a reaction to the first attack, it is an entirely new attack with a new target. Mind Trick specifically says "The attack ends." In another thread about flipping stances, Negoldar said "You would have to finish the attack before you could switch stances once the attack is declared."
