I've seen some people do, I'm going to throw down my thoughts and musings on the set...
Δ Plus - This ability knows no bounds. Dragonite can wield it particularly well with muscle band. Dustox's bench hitter could viable, maybe.
Δ Evolution - It could be helpful for some cards, especially with Wally's help. Togekiss has the best use Imo.
Δ Wild - Amazing to have four resistances. Almost a little broken~ too bad it's only on one already amazing 1hko machine.
>Beautifly< It may be a stage 2, but to have safeguard and the ability to move your opponents non-ex back to bench is really nice, alongside that free retreat yourself.
>Primal Dustox< Great for hitting weakened ex' from Beautifly
>Shedinja< Good setup for M-Gallade. You could possibly abuse his second attack with the correct setup.
>Talonflame< Enough of them already! Some draw power on this one though.
>Primal Arcticuno< 140 damage max, but unlikely. Good for basic. Has Plus.
>Voltorb< Ka-boom!
>Natu< Your cute~ and actually have a little punch. Dimensional Valley revenge killer.
>Primal Banette< Good for early stalling, but not much else going for it. Love the art though!
>Deoxys< Early draw power and a decent attack against psychic-weak Pokemon.
>Absol< Its a weird ability, but could possibly do some tricks
>Jirachi< Dragalge poison lock and destructive wish. Ok searching move too.
>Primal Togekiss< Amazing fairy energy accelerator that can work turn one w/Wally.
>Dragonite< Great Ex/M-Ex support, at least with the same type.
>Primal Dragonite< I hate the ground! Plus-supported heavy impact with muscle band for 170, powered with a quick setup thanks to double dragon energy and his first move makes him a great primal stage 2 with 160hp. M-Manectric's Turbo bolts could also speed up the process.
>Salamence< Another three-move Pokemon! Lots of variety. Fire for 60 isn't bad + stadium discard. Power Howel is amazing unless your opponent is struggling. Steam blast for the 1hko power.
>Reshiram< Turboblaze is great dragon acceleration, plus Hydreigon's free retreat alongside an arena.
>Primal Altaria< My Manectrics are growling.
>Unfezant< Turbulence... it's last ditch, but it would be hilarious, especially on decks that require tonnes of setup!
>Thunderus Ex< All power, not much strategy to him.
>Gallade Ex< I freaked when I saw the roaring skies pack with his mega on it. His art for his regular Ex is better than his Fa Imo. Speed jab is good setup for his mega, and side slasher is a great early game hitter. Supported by dimensional valley as well.
>M-Gallade Ex< The full art is my number one on my to-get list! Mudou blade with some bench hitting support Pokemon could make this move a real threat. Free retreat with a mystery energy!
>Latios Ex< Very interesting first move that can gain an early lead or even win. Light pulse isn't terrible but it costs a little much. I guess we get high costs with the double dragon energy. With Latios' design I would expect a retreat cost of one at most.
>M-Latios Ex< Sonic ace could be devastating but at the same time it's prone to too much energy loss. Nothing is weak to dragon anymore, so the wide lens is useless for it.
>Hydreigon Ex< Dragon Road will provide some excellent support for the dragon class, though thats all he's got going. Shred is considerably mediocre for an Ex. Its nice for taking down Suicune and Sigilyth with a muscle band.
>Rayquaza Ex< Rising burn is great for dealing early damage to Ex leads. Dragon pulse can deal some decent damage with little drawback.
>Rayquaza Ex (Deck ver.)< Dragon strike is nice, but it's got nothing too special going for it.
>M-Rayquaza Ex< That new stadium is quite unstable without a ninetales in play, but this mega hits hard, fast. It could easily be set up on turn one.
>M-Rayquaza Ex (Deck ver.)< I was surprised to see another 1hko machine, but this one is especially viable alongside Reshiram, Mega Turbo and DDE compared to Mega Charizards hefty drawbacks.
>Shaymin Ex< Fantastic support card, even if it's been repeated. Excellent synergy with setting up colourless M-Rayquaza.
>Winona< Great boost for colourless types. Playable colourless may still be limited, but certainly a staple for those decks. Her full art is so freaking dramatic. I love the angle.
>Wally< Fantastic way to get early evolutions in play. Getting a quick Togekiss up is great for fairy decks and viable with Wally's help. It's all I've wanted from and evosoda and better.
>Revive< Its usable, but not a staple.
>Mega Turbo< This will be amazing for getting any sort of mega running quickly. With a lack of energy acceleration in fighting decks, I've ran into problems setting up my M-Lucario Ex when I need him. This could easily help.
>Trainer's Post< Nice way to recover from a bad hand.
>Wide Angle Lens< I can't see this being too useful. If M-Latios Ex wasn't a dragon, this would be useful too him.
>Spirit Links< Helpful as always
>Skyfield< Highly unstable, but opens up lots of options for some fun decks. Ninetales sold separately.
>Gold Item Cards< I'm impressed by the Vs Seeker, it's going to go for a lot.
Overall I'm impressed with some cards, and mildly disappointed by others. Dragon and Colourless have finally got a chance to shine. Mega's get another great addition with the Turbo energy. Unfortunately, anything outside of dragon, colourless, and psychic didn't get much. Fairy has a(nother) nice energy tech now though.
Decks I'm looking forward too >
M-Gallade Ex/Gengar Ex
Dragonite/M-Manectric Ex
M-Rayquaza Ex/Reshiram
M-Rayquaza Ex/Altaria/Shaymin Ex
Togekiss/M-Gardevoir Ex
Dragalge/Jirachi
Dustox/Beautifly
Thanks for reading if you bared through it all. I just had an urge to write a lengthy musing on it all. Why not post it here.
