Natnew, this sounds like you want it to be a Christmas event of some kind, but I really don't like it, to be blunt. The due date is too short (we're 10 days from Christmas) and the list of Pokemon is beyond too short. RSE is completely excluded, unless someone is able to hack or trade, for example. Plus, since it's not like old Christmas events, it would still be up throughout the year and it'd be kind of strange for people to play a Christmas challenge in February or June.
