I don't mind Rockruff's evolutions being version exclusive but it's disappointing to see that the Midday form gets a cool new Rock type priority move but the midnight form gets Counter :/
Nice deck, something I'd like to try out as well. I'd say add some Level Balls to find key Pokémon and a Wally in case you haven't got your stadium out yet. Having a Skyla too works if you need a specific trainer in a pinch.
I've played against a deck using that Ancient Trait Togekiss from Roaring Skies with its Serene Grace ability allowing it to pull multiple basic energy from the top 8 cards in your deck. Definitely inconsistent but can work well getting Golem EX powered up quickly
Mega Audino looking good with easy bench sniping attack and Delphox with that fire energy acceleration.. I'm almost drooling at the possibilities with it.
The one I've seen is Bronzong/M Scizor EX/Zoroark deck using Bronzong's Metal Links ability to get Metal energies from the discard pile and power Scizor and M Scizor EX as well as Zoroark with Mind Jack. Bronzong and Aegislash EX is also a thing too. I forgot to mention decks like Trevenant...
Off the top of my head that I've seen is Greninja BREAK, Vespiqueen/Vileplume, Entei/Charizard EX variants, Bronzong variants and a few other miscellaneous decks. Bear in mind is this just based on my experience on PTCGO only though.
