Jirachi Promo was interesting until it was Prized or something I simply could not hit it at the right time. No doubt it's a cute tech, but it just dies to Greninja and Volcanion, arguably the two other top decks in the format. I like it against RaichuBats (which is starting to become a thing holy crap) and Bees/Zebstrika, but I feel like other than those matchups...it's kinda dead. Plus, they play Special Charge so the disruption isn't as hard-hitting as it used to be. Unless, of course you time a dirty N to one and they're left with nothing. Funny you mention PlumeBox, deck is completely dead around where I am. I also haven't hit any matchups against it online in some time, except maybe like once.
