Okay don't worry about it you have to trade to get gengar but if you get the national dex go to old chateau and go in the room with the eyes on the wall a little girl should appear in the room on your right and walk around in that room for about 20 minutes takes a while but works I'm just sayin 20 because it took me ten and my friend 20 so walk around for twenty minutes and bam a gengar about lvl 17....
