This card game hasn't exactly been creative, or well-managed in such a long time. To be honest - I welcome this "Archetype" theme finally being added to the Pokemon TCG again. It creates budget decks, and allows players to build decks based on their favorite characters that are still decently viable. Cynthia as a deck has made me want to play the TCG at least casually again. I love Lucario, I love Garchomp, and Cynthia is right up there as one of my favorite champions.
If the Pokemon TCG keeps doing this, and does even more of them, then we'll have an alternative for players who are on a budget in this crazy localization game of "Let's not release the same products Japan does and opt for insanely overpriced product." Not just that, but there will be fun decks running around.
I know we haven't seen translations yet - but looking at the Dragon Storm leaks it's already fairly obvious that Blaine might have something to do with Charizard. So this could mean they intend to keep pumping decks like this out.
