Wynaut run the same Wallbreaker set the Crobat runs?

Taunt stops anything from setting up or statusing you, while Toxic could ruin some bulkier threats but isn't really advised, and U-turn is a personal favorite of mine for breaking hitting Psychic types, revenge killing, and gathering momentum. Super Fang deals 50% to anything at full HP all the time which is really nice for wall breaking, Roost is recovery, and Brave Bird is your STAB.
Also, think about adding U-turn to your current set, it could help hit things like Abra and other Psychic types.
