Monster Train is very similar to Slay the Spire but with more imba interactions, can be very fun. One Step From Eden combines deckbuilding with fast paced grid-based bullet hell action. I haven't played Heretic's Fork yet but it looks like a smooth fusion of the survivor genre with deckbuilding characteristics. Noita is really not a deckbuilder but I'd be remiss not to recommend it, it has some deckbuilding mechanics but until you play for several dozen hours you won't really get a lot of use out of them, they're hidden from the player mostly.
One Step From Eden is like Slay the Spire had a baby with Megaman Battle Network and then someone gave the baby access to caffeinated beverages, it's pretty fun.
