If you have something you're willing to trade (or clone, or have me clone, etc.; we'll figure it out), I am going to do the event later this evening, likely; since I want good stats, I might run the receipt on my older DS, so I'd have to do it after DW and Join Avenue events this evening.
So, I can do this:
1. Send it from receiving it to Black.
2. Clone it (Action Replay).
3a. Trade the clone to you.
3b. If you want me to clone the trade and send the original back, I do that, and you send a Junkémon the second time.
4. Keep a clone in Black and send the original back to W2.
You'd get your Deoxys that way, granted identical to mine. Whatcha think?
