Hey. I use Unreal Engine currently, but I'm open to trying new engines too.
I don't have direct experience with making card games, but I did make a prototype of a game inspired by Phantom Dust, a 2005 OG Xbox game that is like a TCG but as a real-time third person action game.
feel free to try it out. and let me know if you are interested in having me join in to give some input on the game design.
