It doesn't ignore,it just adds another. And Synch blade is a Dummy ability,doesn't do anything,but you should put it as well. And since you guessed,i will too,i think that Reflect dummy is what makes his fists hit the enemy,i know it's wierd but i think so. And Over dummy is what makes it loose the Keyblade(But the effect of the Keyblade still stays there),if not is something about the double loss of HP. Just guesses of course.
