so they outplayed you?

it is significnatly harder to interrupt then cast a well timed jutsu, do not rely so much on the visual appearance

a perfectly timed mystery wont show the icon, you do this by waiting to the very point that an animation is about to end to que your mystery so it instantly casts the second you do it, this means that interrupts have low chance to occur

if you know what your enemys strategy is you just have to outthink them and know when and why they want to cast that jutsu, theres a perfect and ideal time to cast, always
