I'm only concerned with control decks. Control loses a bunch of good cards and, up to this point, not much is available to replace it. We currently know of 2/3 of Unified Minds (we don't have any spoilers for anything in the third set...Miracle Twins? Wonder Twins?). Here's what I have so far:
- Unless we get something incredible in the next set, we have little to no "Ball" support. Things like Ultra Beasts will be big because Ultra Space is a Stadium that acts as a free "Ball" every turn.
- I think the new Naganadel-GX will be the replacement to Zoroark-GX in terms of Zoroark-GX / Oranguru control. Even if you uise a 4-4 Naganadel-GX line with 4 Ultra Space, you can search out a Poipole/Naganadel-GX through 'Space, UB-Trade it for 3, then put it back into the deck with Oranguru. And when you use Ultra Space, you shuffle the deck afterwards, meaning the stuff you shuffled in could be drawn as opposed to forever being at the bottom. Crushing Hammer and Lusamine don't rotate due to them being Secret Rares in Ultra Prism. That said, I think the deck DIES to Naganadel / Quagsire and anything that can get Energy back VIA Naganadel because there's not a whole lot of disruption beyone Crushing Hammer, Mars, Jessie & James; and there's not much in terms of stranding options because Guzma is out of the format. Custom Catcher is seriously the most viable option.
- Naganadel / Quagsire will be the most viable 1-Prize deck. This is especially helpful because it combats the Fire decks that will be rampant as Blacephalon-GX doesn't lose much and I don't think the Charizard & Reshiram-GX decks lose much either.
- Because UBs will be good, things like Unbroken Bonds Marshadow and the new Tapu Fini in Unified Minds must be considered as techs.
- I think the format will START as very Item dependent, menaing something like a solid Gengar & Mimikyu-GX / Omastar deck could be massive. It doesn't lose much to rotation, but it does have some serious consistency issues due to its weird design.
