ITT: We create new items
I'll start off:
>Skill Inhibitor
>One time use item. Once, it can negate certain abilities activated by the opponent's pokemon. Such abilities negated include Defiant, Magic Bounce, Wonder Guard, Sturdy, Flash Fire, Water and Volt Absorb, Sap Sipper, etc. Does not negate abilities that do not show themselves activate, such as Tough Claws, Skill Link, Gale Wings, etc.
It basically grants a one-time Mold Breaker. Good for hazard setters that want to give the middle-finger to Espeon.
