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.
Pokemon Let's Go Pikachu and Eevee were recently released and their system for Pokemon Battles is very different from that of previous Pokemon Games. Pokemon Showdown will have to be edited to play in this format. What I am concerned about is how Let's Go is still in the gen 7 family of games...
I liked Moomoo paddock as it was where I encountered one of my favourite Pokemon: Miltank. I also thought the idea of the abandoned Thriffy Megamart was cool.
