Griftlands is also great for a more story-driven / impactful decisions deckbuilder. Sort of STS wrapped in a well made RPG. Similar game mechanics as you laid out for Monster Train/STS but with the "twist" that there are two types of decks that you build each run, one for negotiation and one for combat. Many encounters can be approached either way, and your ongoing relationships with the other characters give you buffs/debuffs and shape the story.
