I really like Cursed Body. The first time I had to deal with it was in the Battle Subway, on my 20th battle. We were both down to our last Pokemon, I had Cobalion with Sacred Sword, Retaliate and Iron Head. He brings out a female Jellicent. On the first turn it disabled Iron Head, the only move I could have used. And well, I lost. As of yesterday I have my own Cursed Body Jellicent, and she's really fun to use.
