Sweeps, and the fact I had the little side for Shuckle (not a favorite, but this guy is awesome).
Latest run was an even more LOL factor (just wanted to try it really):
The Gorebyss I used to Baton Pass Aqua Ring also put Shell Smash (with White Herb) on it, for faster Shuckle immediate power, haha, as in I usually do one Power Trick and a few acupressures (less regarding attack because of my boosts), and just rollout sweep like "normal". I love it when things set up on me, when in the end I'm wracking Def/SpD boosts along with Evasion and I end up avoiding surviving their attacks after power share and defense boosts and just rollout sweep them. Though some set up sweepers especially if hard hitters with SE STAB, can win if I don't get the boosts fast enough.
