I have 4 games, FireRed, Emerald, Diamond and SoulSilver. I first played through FireRed and Emerald and got a lot of my current powerful Pokemon. When I got Diamond and was able to use Pal Park I transferred all of my good Pokemon to Diamond, including my only shiny. Now, I don't play Diamond as much and was thinking of transferring all of my good Pokemon to SoulSilver through GTS since I only have one DS.
I have two problems. One I can't decide if I want to transfer my Pokemon to SoulSilver or keep all of my strong pokemon on Diamond.
Also, I can't get some of the Pokemon through GTS, there names don't appear. The Pokemon that don't appear are Aggron, Meganium, Vibrava, Swampert, Leafeon and Glaceon. The only Pokemon out of those that I really want is Swampert, it was my starter Pokemon from Emerald and is now level 100. The others I don't want as much.
Can you help me decide whether or not to transfer and also how I can get it so I can get the Pokemon I mentioned?
Thanks in advance!
