This card will be a Psychic type and most likely will get a VMAX card too. No more information has been revealed when reading the flyer. It's chosen Psychic typing is interesting since it's also Dragon Type in the videogame. We are curious what will happen with Dragon Type during the Sword & Shield TCG generation.
In addition to this, it also mentions a unnamed Pokemon V card, which has an ability when you put it on your bench from your hand, and a Trainer card that switches your opponent's benched Pokemon with Active Pokemon.
This set will contain 96 cards + Secret Rare cards and it will release on March 6, 2020.
Stay tuned for more information later in February after S1a VMAX Rising has been released!
