Hi there. Here is a Pokemon TCG post. I am a month behind on this due to my vacation. This news release was from mid August 2024. I write this in mid September 2024.
Both of these cards have an unknown release date as far as I know.
Lillie's Clefairy ex

One of the big releases from the Pokemon World Championships 2024 is Lillie's Clefairy ex. The game designers are bringing back Owner's Pokemon.
Lillie's Clefairy ex does have low HP at 190 HP for a 2 prize Basic Pokemon. The attack of Full Moon Rondo does 20 plus 20 more damage for each Benched Pokemon in play from you and your opponent.
What stands out is the Fairy Zone ability from Lillie's Clefairy ex. Your opponent's Dragon Pokemon now have weakness to Psychic Pokemon (x2 damage from Psychic to Dragon). There are no Fairy Pokemon in the F, G, H regulation format of the Pokemon TCG so having a card that can enable weakness to Dragon Pokemon is powerful. Dragapult ex decks and Regidrago VSTAR decks that are popular in the Shrouded Fable and Stellar Crown metagame will take a hit when this card releases.
Marnie's Grimmsnarl ex

Marnie's Grimmsnarl ex is a Stage 2 Pokemon ex card that evolves from Marnie's Morgem. It is unknown about the information of Marnie's Morgem or Marnie's Impidimp.
This Stage 2 Pokemon has 320 HP and is of the Dark type. Its attack of Shadow Bullet does 180 damage along with doing 30 damage to 1 of your opponent's Benched Pokemon. This attack is kind of weak but it does cost 2 Dark Energy which is not that expensive.
The ability of Punk Up activates from this Pokemon is played from hand for evolution. You can search for up to 5 Basic Dark Energy cards and attach them to Marnie's Pokemon in any way you like. This a powerful Energy acceleration ability for powering up more of your Marnie's Pokemon in play.
