First of all, the hypnosis thing is a type of technique, so urahara might have a counter for it. also with his equipment aizen's sword would just attack one of urahara's fakes. so hypnosis might not work. we dont know what urahara cooks up in that shop.

also if there wasnt a way to beat aizen's techniques, then how would the main character win huh. im guessing by something urahara teaches him
