It’s normal to be skeptical no worries ;). Pokémon TCG is really a thing of its own, and managed by a separate entity within the Pokemon Company.
I could be wrong, but if it was the case, I am wondering why they did not already do it with their new TCG app that was released last year.
Depends how you see it. TCG is by itself a lootbox game, but with physical cards instead. However, it does not seem that the Pokemon Company wants to turn its TCG game into a digital business, but instead use those apps as promotional products for TCG. Personally, I think it’s a much better model than the one pursued by everyone else. The apps are more a bonus / promotional stuff than a real thing. For this particular app, I won’t be surprised if there is no other way to get packs than waiting for the next day.
