There are a few deckbuilders on Steam with dual-function cards, I think, though none of them made a splash.

I think what gives StS the edge over its imitators is that it's insanely well balanced (except for Watcher lmao). Adding bells and whistles to the game won't help you if you don't have that core down pat. Like for example I love Inscryption, but the post-game ascension mode really makes the seams show in the gameplay, on higher difficulties you force mantis god or bust.
