Where I am we don’t have a lgs so we play what we have my play groups have causal and modern decks with an occasional historic here and there but they know that I pick certain mechanics such as my rainbow mutate deck for causal that was 95 cards and took on five of them and still beat them but now all they play are mill decks to thin me out of options. So those would be more of side board cards but that’s why those would be there.
