When EVing the level 1 guys I traded you, can you to the following:
1. Give it the pokerus before Eving it (obvious).
2. Have a party of 5 of your own (EVed) pokemon, and then the 1 pokemon to be EVed first.
3. Have your 5 pokemon equipped w/ Experience share.
4. When battling, always defeat the poke w/ one of your EVed guys (preferably the same one, w/ a "big move" that one-hit kills and has at least 16 PP, so it's easy for you to keep track).
5 When battling high level guys (10-20), swap out multiples of your guys, then go to your 1-hit killer.
You don't have to do this on all of them, but if you could do it on 2 or 3 of the following I'd really appreciate it.
Anorith,Lileep, Carvanha
If you do all this, you should be able to keep them below level 10. If they go above level 10, you can EV them normally I suppose. But I'm aiming to construct a team for BW, so I need below-lv 10 guys. Thanks!
