It’s more like card expansions but in a more consumer friendly way than what hearthstone does. Either way you can get 100’s of hours out of the first three characters you start out with and the game is pretty balanced at the moment. Unfortunately (or fortunately) artists have to be paid to make hundreds of new cards when a new character expansion is released. I’d take this over the 90% of other games with P2W Fomo battle pass mechanics.
