Hey jamvad, I made a team around z-reflect swoobat, it´s pretty fun and can actually work quite well:
http://pastebin.com/9PXiHVwG with this set Swoobat gets 4x as bulky on the physical side after 1 reflect, if you get rid of the dark types on the enemy team it nearly always sweeps, since noone expect the power of that little monster :]
Feel free to make any changes you want
