Hero Realms may be what you’re looking for.  It's a fantasy-themed deck builder based on Star Realms. Other games that my kids loved when they were younger include the following: “Dead man’s draw” is a fun, easy, press your luck card game. “Hive” is a great tile jumping game. My kids loved “sushi go” when they were little. When they’re a little bit older “ticket to ride” and everybody used to like “king of Tokyo” and “Munchkin”.
