Jirachi is _definitely_ optional. Especially if your particular meta is heavily dominated by basic decks (my meta isn't established too well yet). In testing though, it was always better to attack with Kyurem than spend a turn devolving, and more times than not I would never use Jirachi, and instead wished for the psychic energy to be waters for rain dance. I agree with not needing fires now, I seem to always forget that the water attack is still fire typed. I guess I'll leave one in, since it can't hurt, seeing as Kyurem uses WWC.
