I like this. I think giving the characters from GO some representation is a great addition to the TCG. I'd love to see a bit more of that, such as the Team Leaders or the Rocket Admins represented as well, since they are pretty fun characters, despite their simplicity. I hope the TCG does more of the kinds of things like this in the future, it just has some nice collectible appeal to it.
It's especially nice seeing GO get some TCG representation too, as that has been my main way to experience the series in the past few years, especially since I decided to skip Sword and Shield. So it's like, "Hey! Here's something I'm active in getting TCG representation!"
