It does seem too cheap, and I think the deciding factor on whether it could survive would be the special promos included in the Premium package. Stuff like free game currency or skins. The whales would gladly pay the extra to cover the rest of our cheap asses if they can get some exclusive cosmetics.
It’s no less commercialized, and it’s not physical, but I’ve been playing Hearthstone for mostly free for over ten years. Plays like MTG, but faster, and implements a lot of randomization that’s near impossible to do with physical cards.
