Well, VoltTurn is a strategy, not a play style. At least it is in my eyes.
Anyways, Trick Room is a fun play style with NP Cofagrigus, Conkeldurr, and Reuniclus. I dunno, it just seems fun to use Pokemon that are generally turned down for sweeping because they are too slow. I also like Stall and Balanced in OU, mainly because they're both pretty fun to use. Personally I prefer play styles that make me think, but ones that I enjoy at the same time.
