Well I've played over 500 matches with my current team (+previous teams) in the Sub now and I've never seen the opponent to switch randomly. Rest is essential because sometimes you can't cripple your opponent enough for Drapion to setup right away (some EQ users and such or if it's a special attacker you are facing sometimes Memento won't be enough) but you can stall those moves out with Rest and then proceed to setup. Rest would probably help against those special attackers you say you still had problems with. Seems like with your set you would have to get lucky to get the right boosts from Acupressure even if you have managed to lower your opponents accuracy a bit since you don't have any recovery move. With Rest however I'm ~always getting 21 Acupressures done. And like I said earlier, if the Taunt user is opponents starter, kill it. If it is not, then it should not matter since you should have already managed to setup. And I usually don't use Memento if I haven't lost/sacrificed one pokemon before that (usually Bibarel) so that when I setup my opponent doesn't even have the opportunity to use WW/Roar if they happen to carry one. And how exactly does Destiny Bond prevent you from setupping or sweeping (since there are no Destiny Bond users @Quick Claw)? EDIT: And how exactly would Scrafty and Bisharp be of any trouble?
