We play with a set of 40 equipment, 40 superpowers, 40 heroes, 40 villains and 16 locations in the main deck. Each player chooses a non-crisis superhero and a supervillian. There are two stacks of defeatable characters. One is villains and the other is heroes. I took the time to remove some of the "collector" cards (manhunter, suicide squad). I left the power rings. Everything seems to be working fine when we play. It did take some time to sort the cards for cost and redundancy. I have cards from all the sets except rivals. I only kept them separate because I like having a small deck for a quick two player game.
