That would work, except Prisim Stars are done. They aren't making any more.I think this Lillie's Best Effort is going to be an OP prism star supporter with the condition of
"It can only be use if you are having # energy in play"
like the unbroken bond Volcanion's second attack
then the + sign on the attack is kinda make sense
it's like team effort kind of card, everyone have some energy on and the gx attack protects everyone
and the N with Zekrom and Reshiram will be something like
"It can only be use if your opponent are having # energy in play"
you know, because N loves to f*ck up your opponent
