Yea, SD Stallbreaker set should go to OO; almost all Gliscor are either Substitute or the Defensive sets anyways. Electrolyte, you can explain the set in OO, instead. Save your Stallbreaker skelly just in case, though.
I would also move the Defensive set above Acrobatics set, since the latter is a lot less used ever since the Sand Veil ban.
Remove Poison Heal from the AcroBat; Hyper Cutter is just as useful as Poison Heal, so there should be no preferential ability listing here.
