When using dig, shouldn’t abilities like Levitate be voided, given that well, the pokemon is now underground…and levitating is floating above ground…and you can’t do both? Its basically invincibility for the duration of the move.
I agree ik pokemon doesn’t always follow logic but being hax isn’t the answer to your problems. and if you can have the ability underground at least shorten the time you can spend underground to about 3 seconds that would make more sense.
