One thing I had a little success with was a destiny bond doubles team, so I had to laugh. Isn't that your new challend for the week after this week>
But I did some times I had trouble getting my person switched out so that my person did not faint too. The trick is having 3 pokes left when they only have 2 so you can still switch out and stop the counter. I am thinking first round protect and eath quake, next round explosion with a normal poke to knock out 2 of theirs for your one poke, then destiny bond with a murkrow or something, then rotate out to a blissey and you can last them out for the 3 turns and swithc out at least one of your pokes.
