A year ago or so I would have said Clash Royale. But now… nah.
You’ll find plenty of videos that explain this better than I can, but at this point the devs clearly hate the community, the game is more pay to win than ever, evolutions are completely broken and the devs barely care to balance the game anymore.
It’s pretty obvious that right now they just want to squeeze as much money as possible from the game before it completely dies out.
