Well it is a good tech for some decks as it is virtually Lysandre but maybe you play it with Regirock EX, Strong Energy, and Captivating Pokepuff?
I'm just playing it in my Lycanroc/Carbink deck. I split the Lycanrocs 2/2 (2 Midday, 2 Midnight). working pretty well.
I've been wanting to try a Control deck similar to the Zoroark variant. In theory it works pretty well, from the GX attack to the Ability once you evolve it.
