I'd actually like to see more moves that have a secondary effect as lowering Attack or Special Attack. It would be definitely interesting to use, and would fit on both wall and sweeper sets. Going with the normal type theme, maybe a Normal-typed Psychic that lowers SpA by one stage? You could run that on a Porygon2, for example, and have it take special hits better by lowering the opponent's stats instead of boosting up.
