OM Classic II and Retro OMs
Ever wanted to play some of our most favored past gen OMs in a tournament setting? OM Classic II has officially commenced! Our first tournament in OM Classic II is Gen 7 Balanced Hackmons Cup! Sign up if you have what it takes to become the champion of old gen OMs!
To commemorate the commencement of OM Classic II, Gen 7 STABmons and Gen 6 Almost Any Ability are now ladder formats on Pokémon Showdown and will be available to play for the duration of the event. Gen 7 Mix and Mega has also been added to Pokémon Showdown but as a permanent ladder! For more information on the new ladders, check out this thread.
