Is he worth all the Lunchboxes you have to buy to acquire him? Not at all. He just looks like a good character to use. The amount of Gold it takes to buy lunchboxes and then exchange them for comic covers is too much.
He doesn’t deliver as a fighter. Even when he is used on a Distress Call, he doesn’t do enough for me to want to try for him. And based on how easy it is to defeat him, it would take a lot to insert him into my team and to be used as a viable option.
