How can you get a Manaphy through the center of world diamond trade Pokemon?
How do you manage to make one if you do see in the game? I heard that you should have seen the pokemon in the Pokédex to get this Pokemon. Also, if you use the Action Replay is it upside the face-off at all or is it really safe to use it without spoiling the game?
To get Manaphy, you have to have saw the first, or from trade with friends, or having already obtained an egg. You can make a direct trade, and not the channel of world trade with someone. Find a bulletin board where they discuss business, enter into contracts, exchange friend codes, then go downstairs to a PC and connect with them there for trade.
