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.
I’m working on your Hydreigon/Terrakion request today. I really apologize for the unacceptably long time it’s taking. If you don’t have it soon (I’m 3 or 4 days), please feel free to ask about it to me or the project leaders (vivalospride and Amane Misa).
