I just started back into the TCG so still learning. I am making my deck and it says the HGSS rainbow energy is legal in modified format. I have been looking through the deck help thread yet I see no one taking advantage of it. Is this card not allowed and the legal list I am looking at expired or do people just not like to use it? Need to know so when I make my deck I know whether or not to leave it out or not, thanks for any help
