I have been testing multiple decks that get walled easily by alolan Ninetales. I have found a few techs that can help agiainst this, my favorite of them is Oranguru SM. I love how it can easily OHKO ninetales especialy in decks with max elixer like Lapras Darkrai and Mega Scizor. In water decks (like Lapras) I found that running your own Ninetails can work! Again in water decks Tapu Fini GX is also an option. If you run a deck thhat doesn't really use abilities you can use Garbodor BPT to help. You can also try to play around Alolan Ninetails with Guzma but that's hard to do for the whole game. Using Bisharp is an amazing tech because 1. It's a metal type so with Retaliate as long as you had a pokemon knocked out during the previous turn it will OHKO Ninetales. Here is where Bisharp gets interesting, because it's a metal type it can also knock out Gardevoir GX with the aid of Choice Band, Reverse Valley or Dhelmise. My final counter is Espeon EX because you can simply devolve them which unfortunately unless you play Decidueye GX is very situational. That's all the advice I have for countering Alolan Ninetales if you have any other counters that I missed please tell me in this thread as I would love to find better counters for me and anyone who might have trouble dealing with this card/deck and til next time peace!
