I remembered that this card exists and thought that it might be fun to build a deck around it with its damage immunity but then I read what the bonus GX effect actually was. I assume that such a deck would just lose to eternatus poison or raichu-raichu + stamp.
The idea was that if you get 4 energy on a lone marshadow-machamp in play, it can take 4 prizes off dedennes/bats. Pretty much the same game plan as reshiram-zekrom but with extra steps.
