How would you balance Prankster?

>Status moves of the same type of the Pokemon have priority

No more WoW Sableye fucking over your physical attackers not named Infernape. Whimsicott can't Encore your ass into a resisted move. Thundurus-I still powerful with priority Thunder Wave but can't fire off a guaranteed Taunt anymore.

This doesn't fix it very well, and I'm sure /vp/ can come up with better solutions. What have you got?
