Unown VStar

This deck needs controlling cards to hide behind like Klefki or Mimikyu. Blastoise is also pointless. It loses a full turn, where you could just use Geeta to power up or Xatu or Energy Sticker. I like the idea of pairing this with Unown VSTAR, but this deck is so poorly and carelessly designed that it doesn't stand a chance. Unown never was super great, but this deck doesn't even try. You need to get Star Cipher ASAP otherwise you get KOed instantly. It's a good idea, but you need to be more focused with cards to hide behind and Leafy Camo Poncho to stop Boss. You have no draw engine as well.

Apologies if my earlier comment came across as rude. This is a very challenging deck to build. I tried to make a version and it was trashier than a Garbodor. The lack of deck space makes it near impossible to make it go. Some suggestions I have for you to beef up your deck would be replacing Blastoise with Xatu, replacing Nest Ball with Fog Crystal, adding a Leafy Camo Poncho, cutting down on Jacq with Ultra Ball and Capturing Aroma, possibly going a little heavier on Arven, and adding some Klefki and Mimikyu to hide behind while you attack with Dimension Hand. Xatu works as a draw engine and energy acceleration, and fog crystal is objectively better than Nest Ball with Natu instead of Squirtle because of the Energy aearch or basic search. 11 Basic Psychic Energy is also a lot. 8 is plenty. You could also add an Earthen Vessel to get those energy more efficiently. I'd beef up the Alakazam line (3-3-3/3-2-3) and cut all but 1 or 2 Rare Candy (depending on your line). 4 Pokegear 3.0 is also 2-4 too many (so drop 2-4). It does look like a fun idea to try! Make sure to run stadiums to counter Path (it shuts off the ability granted by Star Cipher). Instead of running Super Effective Glasses, you could go bonkers and run Kabutops with Rare Candy (which doesn't make a difference because 360 will OHKO literally (nearly - I'm looking at you, revaroom!) everything). You could also try Pidgeot ex since Path is a big detriment anyways. Have fun with the deck!

I am generally confused here, you run too many of cards you dont really need...
