Here's what I decided to change and why:
-1 Zoroark-GX, +1 Zoroark BKT. The Mind Jack math is perfect with Choice Band and Decidueye, and Stand In+Float Stone is a great solution to the pesky retreat problem. 2 Zoroark-GXes also seems like enough to me. Let me explain the Mind Jack math:
150 (your opponent 's full bench)+10 (base damage)+30 (choice band)+60 (3 feather arrows)=250. This is the ideal scenario, and Zoroark absolutely wrecks face in this kind of scenario. 250 OHKOs everything in the Standard format, and even Gardevoir with it's Resistance to Dark falls to this.
120 (your opponent's almost full bench)+10 (base damage)+30 (choice band)+60 (3 feather arrows)=220. All Stage 1 and Basic EXs/GXs will fall.
There are tons of other good numbers you can hit, but you get the idea. Mind Jack is a great one-time nuke option and also is a good out to Hoopa/Baby 9tales.
-1 Koko, +1 Latios. Decided to go with the 1/1 split since you need the Guzma pivot less with Stand In+Float Stone, and 30+30 to Benched sometimes adds up better than 20 everywhere.
-1 Hoopa, +1 Espeon-EX. I think Espeon is a better tech than Hoopa. It helps in alot of matchups and acts as another wincon that is more easily achieved than the Hoopa wincon. Mind Jack also helps against Volc, so you don't need Hoopa as much.
-1 Guzma, +1 N. I've made the deck a little more snipe focused, so Guzma isn't needed as much. I also feel that 4 Sycamore/4 N is a nessescity in this format, even with Trade and Mallow.
Hope this was helpful!
