Ive been testing Skill Swap Chansey a bit with some good success. Its a pretty niffty trick, one of my favorite things to do is skill swap magic bounce off espeon and poison it / set up on it (with something else). I haven't seen much reunicles, but interestingly, most of them doing even attempt to beat you once they see you have skill swap, very interesting.
It also seems like this ability could work equally well on Blissey.
One last one: Alexwolf you should have your ev spread on Chansey, max defense bold is pretty silly 160 HP / 252 Def / 96 SpD is the way to go, it avoids being 2HKOed by Tornadus-T's superpower after rocks 93% of the time, and avoids a 2HKO from specs Latio's psyshock, without rocks though (and max defense doesn't chance that one bit).
