I really disagree with Taunt SD and defensive being merged into one set. As i have explained already and nobody presented any real objection, the defensive set needs max HP and max Def in order to counter Terrakion reliably, as well as Roost. With Roost Gliscor is able to beat Choice Band Terrakion reliably, as it can easily pp stall its SE with Roost. Protect is shit, because the opponent can always predict it and bring in something that forces you out, meaning you will be unable to switch inot Terrakion's Stone Edge again.
The two sets must be either two seperate sets, or the stallbreaker set should be put into OO (there are not so many stall teams these days anyway, and Gliscor has better things to be doing, not to mention that Gliscor is a mediocre stallbreaker imo. If the meta wasn't so offensive i could see more merit to it, but right now...)
