How would you rank the new supporter trainer cards in the meta?

For me personally,

Red: S tier. No explanation needed

Iono: B or C, arguably the worst this set. She is only good in the specific niche she is in. Aka in decks like gallade and charizard (even then I don't think she is a hard requirement lol). She's not even in other stage 2 decks like skarmzone, meowzone, or rampardos. And of course you could draw into your same hand or give your opponent a good hand

Nurse joy: B. I feel like I've only seen this card be used in giratina decks. She is great there, but similar to iono -- an overall niche pick. Though she might be arguably better because she is a staple that should not be replaced in giratina decks

Rocket grunt: A or B. Found in several meta decks like darktina and meowscarada variants. Can be a big disruptor against other EX decks and is a semi-counter to misty. But if you flip tails...I'm sure you had other supporters you wanted to play

Overall, I think this has been a pretty strong set of supporter cards
