So I was in arena fighting a shippuden Sasuke and they cast kirin. So immediately I go to queue up lightning main's acupuncture skill. They casted it on turn 2 and their sasuke is position 4. My main is position 3. I used my acupuncture skill and it didn't go through until after sasuke cast his barrier. This has been happening to me a lot where I will attempt to interrupt non prompt mysteries and they cast before me with my prompt mysteries.
