Wrote this whole post about the cards only for it to disappear on me at of the blue...so here's the short end of it
Gardevoir/Gallade/Kirlia: What a perfect example of why stage 2s are bad in this format. Here we have the best stage 2 line ever and they just aren't good enough to match up against VMAXs. The energy cost+damage output on both of them need to be bumped up. Gallade is a weaker version of Golisopod DAA that just hits for a better weakness. And Gardevoir's attack cost is way to high for it's damage to be that low, even if it has a great ability. Amazing artwork on both of them though.
Metagross V/VMAX: How do you mess up on this?? It has all of the best support and it can't even utilize any of them to their fullest potential. Maybe there's something in this card i'm not seeing, but when Marnie,boss, and escape rope are STAPLES in decks, that just makes me wonder why I would want to try this? lol
Sandaconda VMAX: Ok I really really like this card. I love energy shuffle attacks because it requires skill to use. Also that first attack is very good too. I can see a Green's sandaconda being played, similar to the Gardevior Sylveon TTGX green's deck.
Blissey V: This came completely out of left field!! And what a card indeed. Someone out there is brewing up a deck idea to get energy on the field and burst it away.....Kingdra+Blissey perhaps...like yeah they can gust up your horsea on the bench, but then they still have a huge threat with blissey. This card will see play and someone is going to find something absolutely busted with it.
Celebi VMAX: Togekiss VMAX exists while you are extremely limited...and that 20 Heal is LOL Milotic exists. This card is bad when there are others that do your job significantly better.
Galarian Rapidash V: At first I thought this was a really good card with that first attack, then I read that it's "Put damage counters on 1 of your opponent’s Pokemon" that immediately makes this card busted!! You mean this thing can put a VMAX on the bench then lower it's HP to 100?!? The amount of disgusting combos you can make with this is insane. That's a RS Urshifu VMAX clean up right there without much of a hassle.
All in All....I cannot wait for chilling reign!! There is insane amount of creativity behind these cards and great combos to utilize that aren't so straightfoward. I joked with my wife that she can run two of her favorite pokemon in a deck....Blaziken VMAX+Galarian Rapidash V...and that's not a bad strategy either lol probably not tier 1, but it's an actual viable strategy lol That is awesome to be able to try stuff out and at least be functionable unlike during the TTGX metagames
