I think all of the card games with random pulls are a bit of a ripoff.

The RPG crowd is the lead in pirating or flat out making their own rules and barely spending money. They just need rules and dice. You need a small group, and there really aren't tournaments so you can play it however you want.

Table top war gaming in the middle is being filled with indy 3d printed miniatures and home made rules that can take over local scenes pretty easily. 40k still dominates the space, only because most people act like its the only game (it is by far the most common already) and you can buy the minis from most any hobby store. The tournaments are huge, and sometimes the biggest tournaments even dictate the rules just as much as the game seller and most people want to play "tournament legal" armies only.

MTG and other card games are the only thing keeping most hobby stores alive and prints money. it is entirely on for whatever reason, people just want to buy another booster. It is as bad as gambling if not worse, you don't even know what you are buying. It should be even easier to pirate and print your own resources to play card games but somehow it is a huge money maker because as always, people flock to the largest group of gamers in their space.

Indy RPG and Skirmish tabletop games make boat loads of money for small groups of people and it is easy for them to run circles around larger game manufacturers. Things like 40k and MTG where there is such a huge following of people who might not necessarily care and just want to go to massive tournaments it is much harder to challenge those established followings.
