I found an x-kryptonite taped inside of a pack that had the common superman, superboy, supergirl, the eradicator, and the chase reign of the supermen Superman

It's always been one of my more favorite objects, certainly my favorite kryptonite. There was actually one match that was won in last weeks tournament, with a great deal of the victory being owed to the X-Kryptonite. I was using a soldier team including Dirk Anger, Faramir, and rookie Domino... The positioning advantage it gave me for these stealthy characters, particularly for Dirk Anger, went a long way to making sure they were always in the right place at the right time. So I would say if you like cheap stealthy grounded figures, X-Kryptonite should be your go to object of choice.
