Before we start blaming a digital trading card game for the sins of capitalism, let’s both acknowledge that “artificial scarcity” is built into games. Mario suffered “artificial scarcity” when he didn’t have a red mushroom at the ready. Anything that requires “unlocking” can be argued to be artifical scarcity. At the end of the day it doesn’t really matter because these are aspects of a game and not real world resources.

Every digital TCG - Hearthstone, mtg arena, etc. all already have artificial scarcity.

This is just allowing for you, as a player, to actually have a semblance of ownership over the digital goods you obtain, independent of the company you purchased it from, which is far more than any other digital platform will allow for.
