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.
IMO PO is superior to showdown. The laddering system at showdown is harder and once I lost points for beating a noob. You dont know how many pts you're gaining when you ladder there, thats why I stayed at PO.
-_- what about the credit to me for xatu and empoleon? And btw xatu is still 2HKOd by sableeyes foul play with your spread( you didn't copy mine right).
