Since I'm merely at the point of trying to complete my dex right now, do you have a Tangela? It's the only swarm poke I haven't been able to catch. Just about any other non-catchable poke in d/p since I don't have any of the older games and so can't use pal park. Extra legendaries you don't need, etc. Just about anything.
I should mention that this Politoad has Belly drum incase you are able to breed that onto another poke. I don't know how egg moves and breeding work exactly, but he's not half bad. Spent two hours fishing for a king's rock to make him. Ugh.
