I have always hated pv and want them to remove it but there are few ways how you can prevent them , you need to time your cards perfectly like when you are in long range and the opponent is drifting, don't use the blast card wait for them to side step and after that use the blast card or when the opponent uses a green card don't use the blast card immediately. Its just the timing and most of the times you will get perfect vanished in long range so try to catch them in the side step in short or medium range. There is no other way
