Hey~! I've got a level 100 EV'd Almia Darkrai with a 405/405 maxed out sp.atk stat and a 336/349 speed stat. I can also add a Timid shaymin to that for your Arceus. The shaymin has all IV's over 25! It is a Flower Paradise Shaymin!
I've started IV training recently, and yes, it is extremely annoying. Seeing as everyone says EV training is easy, and considering I still have a few pokemon with pokerus, that should be the easy part when it comes into play.
Anyway, take care. I'll get to finishing off my team.
Just came to see if you're finding pokerus helpful. Been ages since I gave you it, I believe... well, about two months. Hope you have success, or continue to, with the pokerus I gave you. Also, thanks again for the Riolu.
