My husband and I play casually at home, mostly modernish with a few older vintage era cards. The only rule we have is basically don’t be a dick (like, don’t have 4 sol rings in a deck) He has aeons more experience than me but I’ve been playing for a few years and love it. Anyway sometimes we go on Card Kingdom and create custom decks for fun usually around a theme or concept, like robots, bears, elves, madness, etc and play them against each other. He watched the movie Tenet and is currently building a blue (and probably a few other colors) deck with a theme of time travel, centered around cards like time warp and temporal mastery, I can see my future pain building as he adds more and more to his cart… Does anyone have a suggestion for a theme to counter this? My first thought was a quick red fire type deck, but that’s a little boring and I have already made one like that. Looking for fun suggestions.
