I am pretty new to the game. I’ve seen most of my thoughts, such as trading amongst alliance members and fusing heroes, in previous posts. One that i haven’t seen, and maybe just missed, would be to have characters similar to Exodia where you have collect and match body parts (head, torso, left arm, right arm, and legs). The body parts could have different colors and stars. You could let players mix and match them. Have logic built to where they always share the damage. When the weakest body part loses all of its HP, the entire hero is defeated. Have it set where these characters maxed out would rival the maxed out version of 5 heroes of the same star rating. It could be fun.
