It's been a long time coming, but today we're proud to announce that we've updated the TCM to include all the new Pokémon and forms from Pokémon Ultra Sun and Ultra Moon. This includes the new Lycanroc Dusk Form, Necrozma's new forms, the new Ultra Beasts, and the as-yet-unreleased event Pokémon, Zeraora. You can find them all in the Pokémon tab, as usual.
We've also updated the existing Ultra Beasts to be known by their names, rather than their UB codenames. Hopefully this makes them easier to find when searching for the perfect team for your card!
