I guess no one else runs stall, because Gallade definately has that "BL feel." Atleast to me. I don't want to run a Swellow on my stall team thank you very much. I'd rather have Yanmega back, it was much easier to handle then Gallade.
-Spiritomb +1 other team member-
I've been running a stall based balance team myself, and honestly bulky spiritomb to lopunny (I had been using chatot, but he is pretty much dead weight aside from doing okay against physical venusaur) w/ encore beats it fairly reliably. Go to tomb, shadow sneak as he hits you (no ev investment does ~ 50 bringing him in ko range after SR and/ or LO) and he HAS to shadow sneak to ko you, and then you can go to Lopunny and encore. That halts the would- be sweep and you can now switcheroo a flame orb, heal bell, or return it to death; basically whatever you want. If only she had instant recovery...
-I basically used this because I wanted to have heal bell AND a fast encore. Too bad chatot doesn't learn heal bell or he would actually be REALY useful to me (the only uu pokemon that could even run those moves with the needed speed and flying typing is a scarf togetic).
-Alternatly-
Stall hates this because its very risky, but its another way to beat it. try to get gallade at ~50% as he sets up which shouldn't be too hard if you get to attack twice. Then go to spiritomb to take the close combat(hopefully) and shadow sneak for the ko.
Basically the moral of the story is to use shadow sneak...

-Spiritomb Alone-
Spiritomb w/ a choice band is not exactly a great thing for a stall team, so I have opted for the more complicated method mentioned above. Anway... Banded adamant shadow sneak will ko more often than not w/ SR damage (though according to the calc I did it isn't guaranteed until it takes 1 LO recoil). However, that means losing a TON of bulk, and in my opinion its just not worth it.
Obviously screens throw a huge kink in this plan, but in that event I just go to Lopunny and encore as it subs or SD's making it switch out or die.
I pretty much hate gallade.

EDIT: Togetic has move slot syndrome(it wants wish+ protect, trick, heal bell, encore, and tri attack), but it does give me a nice immunity to ground + a decently fast encore so long as she still has her scarf + heal bell + a trick user that NO ONE sees coming.
