I'm honestly still at a loss with tech Pokemon options for Alolan Ninetales GX decks.
Other than 3 Alolan Ninetales GX, 2 Baby Alolan Ninetales, 2/2 Remoraid/Octillery, and 2-3 Tapu Lele GX, everything else is kind of undecided still.
I don't like Tapu Koko as much now with Acerola running around. Not everyone will play her, but I can't know that in advance. Tapu Koko effectively makes your whole opponent's board viable for an Acerola target, and that's not a risk I'm going to take. I don't want to put 2 damage counters on a Tapu Lele GX and give my opponent the option to use her again without occupying extra bench space.
Sudowoodo isn't an option anymore for me because it makes both you and your opponent drop to 4 bench space. Especially with my train of thought, I don't want to reduce my own bench space when I run more Tapu Lele GX to compensate for the loss of VS Seeker.
Tapu Fini GX has more to offer than just her GX attack. She's a 1 energy switch with aqua ring, and it's a reusable switch. In other words, Aqua Patch your Alolan Ninetales GX on the bench, Aqua Ring to Alolan Ninetales GX if your opponent's active isn't a threat, start sniping next turn. It's slower than float stone or Guzma, but it's a 3rd option to change your active. The 120 snipe is also super powerful with the ability to OHKO Shaymin EX and both Garbodors on the bench. Also, Ice Blade + Hydro Shot = a 2 hit KO on any of the Tapu GX's on the bench, aka Tapu Lele, for 2 prizes out of nowhere.
For me, Glaceon EX completes the defensive package. Baby Alolan Ninetales protects you from EX and GX, Glaceon EX protects you from non-EX and GX evolutions and most useful BREAK decks. Don't forget that Metang can 1 shot Baby Alolan Ninetales, and I would say it's reasonable to expect more Metagross GX decks with Alolan Ninetales running around. Second Bite is also incredibly useful for finishing off an active Pokemon that you've already been sniping with Ice Blade and lets you clean up your opponent's active without constantly discarding DCE's off Blizzard Edge. Second Bite is just more efficient usage of energy as long as you've hit your opponent's active to roughly half health.
I have also been considering 4 Guzma AND +1 float stone because this deck is all about tactical positioning. You need full control over when you're tanking with Baby Alolan Ninetales and Glaceon EX and when you're sniping with Ice Blade or going for the kill with Blizzard Edge/Second Bite.
I have considered Jirachi, the one with Stardust, as it just barely makes it into the 2018 rotation. For 1 energy you can knock off a DCE and become immune to damage for a turn, but I really don't know.
Maybe there will be some better tech choices in the near future, but honestly I'm very undecided on all of them right now.
