If a creature has power and toughness written as / with an ability that defines its power and toughness, its base power and toughness become 0/0 when it loses all abilities. Mystic Subdual then makes it a -2/0. If its power and toughness are written as /+1, it’s -2/1, and so on.

Mutating the enchanted creature won’t cause it to gain abilities. This is because mutate modifies the creature’s base characteristics, while Mystic Subdual applies to the resulting creature.
