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'd Like to see animated versions of some of the backsprites, specifically for Necrozma Dusk mane if it gets picked and Hisu Lilligant. Hisu Lilligant doesnt have much reason for getting added on to but I like it. Another suggestion is Tapu Fini since it gets a TON of useage in Nat Dex Doubles.
