This is a Trainer card called Erika’s Invitation from the Scarlet & Violet 151 series. It is a Supporter card, which means you can play only one during your turn. The card shows Erika in a traditional kimono, holding a small glass orb with plants around her. When you play this card, your opponent reveals their hand. You choose a Basic Pokémon from it and put it onto their Bench. If you do, that Pokémon becomes their Active Pokémon.
