I don't know what Pokemon you have at disposal but Crobat Confuse Ray Taunt, and Heracross has been working well for me. Just get something that can either take a hit, or is really fast with Confuse Ray or Thunder Wave. Then in Crobat's case, against the occasional Blissey, Chansey, or Skarmory, use Taunt. Then switch to a sweeper. Something fast with a choice item or life orb is the best. Otherwise something with Swords Dance/Dragon Dance/Quiver Dance. Example: Shuckle w/ Sticky Web, Toxic, Rest, Coverage Move Sacrifice ^ after Sticky Web and Toxic Stall if Possible. Could even get a Poke with Memento or Final Gambit. Charizard w/ Dragon Dance, Flare Blitz, Shadow Claw, Coverage Move Gengar w/ Shadow Ball, Psychic, Focus Blast, Hypnosis/Dazzling Gleam
Destiny Bond could work. I prefer something with Final Gambit or Memento. Memento you can sac, then just boost away on like a Flygon or something. Scizor too I tried Destiny Bond once on my god Wobbuffet but I kept getting crit
