While it's a very forgotten card, Delphox gains plenty from kiawe. The fact that you don't even need the energy on the active makes it even better since Delphox is similar to Darkrai EX. not only this, but Delphox decks usually run some kind of acceleration anyway, so being able to use kiawe t1 and volcanion\turtonator the two to have over 9 energy on your board (theoretically) and hit for 180 is too promising. I think people skim over Delphox, but it has huge potential in a slow metagame.
