Wow, Franceschi sure did link you to a lot of places.
(Be sure to visit them all... or Hiidoran will come after you with a stick! xD)
You'll have to excuse my craziness... I tend to be this way after a few hours of school and downing a few cokes. ;D
So, you're looking for some event Pokémon, eh?
Well, I'm sure you will find what you need here. The members over in the Wireless Trade Corner are pretty darn friendly and might make you one heck of a deal on some of those Pokémon you've been eyeing. :D
Just remember that there currently isn't a way to capture the "God of all Pokémon," Arceus, without using a cheating device.
(The Pokécommunity frowns on such actions and prohibits the trading of such Pokémon...)
So, if you're looking to completely fill your Pokédex... you may run across some troubles. However, you seem like a decent fellow and I'm sure you will have no troubles abiding by our simple rules!
Well, I fear this is the end of our little chat.
I do wish you all the luck in the world with your Pokédex completion efforts!
Welcome to the Pokécommunity.
