Shadowverse

They offer a bunch of events.

These are irregular and tied to specific events, and they also force you to spend time and play just to stay afloat with the increased costs (and when an event or holiday is perceived as compensation for the rip-off rather than a gift, it's not a great indicator). However, they constantly milk players with expansion packs and come up with new ways to extract money every few months.
The meta, as well as the gameplay of many classes, has improved, but this is due to the rotation itself. I can only praise them for finally gathering the courage and imagination after two years (lol) to start creating at least some interesting mechanics.

Overall, I don't care about the high prices because I'm a veteran player, I have a large collection, and I'm also a minimalist, so I don't spread myself thin across a million expensive decks. But the way they are increasingly and more aggressively milking the player base is obvious. I can only sympathize with the F2P newbies without savings and a collection – I feel that starting in 2018 is not as easy as it used to be. But I won't.
However, there is definitely a negative aspect with this expansion – some classes are completely useless for two months because the developers decided so, and then they "fix" it and artificially buff them, so the old favorites fall to the bottom, and everyone rushes to invest in the new ones. This is a completely cancerous design.
