When you're muted just change your computer's time a few minutes ahead.

For skills, if you're fast enough you can change the time a few minutes ahead while in battle(most useful in pvp), I use Alt + Tab to switch between the two quickly.

It only works 2 times and then you get disconnected, also if you're using a move with a effect like thief of hours then you have to wait for the effect to fade to use the move again or you get disconnected.
