So, with the new Avatar set finally coming to MTGA, there are new Commander cards also.

In a attempt to craft them and power my Brawl deck, I got notified that it's impossible to craft said cards with Wildcards. Thought they were Pay 2 Win in a way that you have to buy them in the Shop in order to add them to any deck, checked the Store, and there was nothing there related to said cards.

So there are cards that exists in the game, you can't craft and you can't buy, and there's no in-game clue for how to get them.
