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.
put something obscure that you don't want on the GTS, record it's details (gender, level) and tell them to me, and ask for a level 9 or under male Snivy - I'll find it and trade it to you later. :)
It may have been sniped, there's no Skarmory on the screen that's being offered for a Snivy. Maybe check, and if it hasn't been sniped reupload it just in case! This happens sometimes.
