I just recently got my B/W versions (by recently I mean like.. a week ago XD) so I don't exactly have a wide variety of pokemon that I would be able to trade just yet. I did get lucky and manage to get the Gamestop Meloetta though. That seems to have made a major difference x]
I have a Tohoku Victini if you'd like to clone one (or a few) for yourself
Other than that, I really don't have any other event pokemon at this point. As for random pokemon, I really don't have many of those either XD trying to get a few spare of the event pokemon I do have so I can trade them for other events/random pokemon and start a nice little collection x]
Anything in particular you want that I could possibly get my hands on?
You need an Action Replay to clone. That is, this:
That particular model is also 3DS compatible, and with X/Y coming, I think there will be accelerated demand for it everywhere soon (cloning in X/Y will be solved by someone). Been slow coming to Canada. I have a standard DS model.
So yeah, that's how I clone. If you'd like, I can create a whole bunch of clones you can stick in your PC. All you have to do is trade me bullsh*t Pokémon for them. Purrloin for Meloetta, Pidove for Meloetta, and so on. I'll send them away afterwards since no one really needs them traded. :D
And yes, you are urged to be cautious about things like this, people asking to clone. As a note, I already have all 649 Pokémon (every single one I have is legit. too, I did end up with a hacked Jirachi and Arceus but they've been replaced, and my existing Japanese Meloetta was acquired by cloning and trading a Keldeo). Therefore, you know up front I have no reason to want to keep the Pokémon afterwards without sending it back. Frankly, I wish they'd trust me for the cloning list, so having people who can vouch for me is something I'd love to have.
So yeah, as long as it's an untouched Event, it's something that people will definitely want, so having a bunch ready to go would help you acquire almost any Pokémon you want easily as time goes on and the event is no longer available. For instance, do you have any idea how hard a Flying Pikachu is to get? Took me some searching, but I finally got it and it's also in my collection of friends now. I'll be curious if it can be imported to Gen. VI someday (since HMs generally won't go through).
I don't know off-hand the nature, but I have a V-create Victini (cloned) that can be traded. I will eventually take both of my games to claim a pair of Meloetta (to go with/replace my Japanese one I traded for to complete the Pokédex), but extras don't hurt. Were you looking to have it cloned, or are you cloning it so you can still keep one?
