A new trademark got filed by Nintendo, Creatures and Game Freak. And it's called V-Union.
Falls under Class 28 - Games, toys and playthings, where the TCG also falls under.
What will it be for? Could it potentially be a new type of VMAX cards for the Calyrex forms in the upcoming future sets S6 / S7? Jet-Black Poltergeist and Silver Lance got both trademarked a while ago too. We think it's meant for Calyrex V and Spectrier V, and maybe for other Legendary Pokémon too, that got introduced again in The Crown Tundra DLC.
We will see next year in 2021 what V-Union will do.
