>>51859442If you see Solar Blade Zacian then chances are you're fighting someone with a Groudon somewhere on their team. Non Groudon variants are more likely to run Wild Charge instead.
As for Power Herb, that's a pretty uncommon pick, usually its Scarfed or Banded and Quagsire has to be careful because a bad switch-in can easily result in it getting killed as its just a check and not a hard counter.
