Only vaguely related, but the site (https://pokemontcg.io/) that the high resolution card images are from is very big and fancy for something that is:

...which surprises me, because in general Nintendo are Not Amused by people making money off of their IP... but, it's been around for a while, so I guess they don't care?
I don't think Nintendo is very involved in the TCG. The Pokémon Company is a separate company, though with 1/3 ownership by Nintendo. Nintendo only really steps in for titles published on Nintendo hardware. The card game and the mobile games are fully under control of The Pokémon Company.
I don't know elsewhere but where I live it's 10x easier to buy pirated Pokemon cards rather then the original ones. You can even buy them in Amazon (but that's nothing extraordinary).
