Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Tornadus would be great! If you're not willing to part with it, can you wait until I get my hands on a thundurus? That way, I can give it back right after I get the Landlos.
Hmm. I'd hate to turn you down. Do you have any extra EV training items/Thunderos/Tornados (and really, I don't need to keep the thunderos/tornados; I just need it to unlock landoros).
