Cardaclysm is a puzzle-like card game in which the first turn or two are the most important. A single hit to your avatar will cause a loss, so basically you want to kill everything first turn, or play just enough cards so that your retaliation will allow a clear on the second. It’s kind of interesting but also incredibly simple.
Monster Train is essentially Slay the Spire with tower-defense elements. The games are extremely similar and if you liked that then this will be right up your ally. The Last Divinity DLC is worth picking up as well since it both adds more to the base game alongside a totally new (and optional) final boss fight which plays markedly differently.
