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.
Do remember to post in the Workshop if you get a banner for a thread through other means (referring to the UU Teambuilding Lab). Current one looks nice!
Btw HP Ghost sounds better overall for CM coba because the 1 stat point doesn't matter unless it is speed (which I don't think Ghost lowers?) because Ghost doesn't trigger random Justified boosts like Dark does (which matters more than 1 stat point lol)
