Where can I receive a Haunter in a trade?

How do you get a Gengar from a trade? You have to evolve a Haunter by trading one to you - a Haunter alone is not going to work. I have looked everywhere in Pokémon Y to find someone to trade a Haunter to me, since I have a Gengarite.

Solution 1:

There is no NPC in Pokémon X or Y that will trade you a Haunter. In order to get a Gengar, you simply have to trade Pokémon with someone who gives you a Haunter (or just trade your own Haunter two times).

This means that you have to trade with another human in order to obtain a Gengar. This can be done via the internet or local wireless communication. You can technically receive a Haunter or Gengar from Wonder Trade, but the chance of that is very low. If you're lucky, you might even find a reasonable trade on the GTS! Your best bet, however, is finding a friend who owns Pokémon X or Y.

Once you are able to trade with someone, simply catch a Haunter on Route 14, Route 19, in Frost Cavern or at Victory Road and use it for trading.

Solution 2:

You can always check the gts or just trade with a friend. I've seen people on the gts offering a haunter for haunter so they can get gengar or machoke for machoke to get machamp. Etc etc.
