Yeah, StS really ruined me for other deckbuilders, and I’m still chasing that high. Some pretty good ones have been Power Chord and Banners of Ruin. They’re both team-based games where cards are tied to certain characters, and I think that particular mechanic adds enough that it took me a while to crack the code on them.
Seconded! Been using the suite for years and it rocks. It’s also multi-OS compatible, which is super handy.
