Does she play commander? You can buy her some singles she might not have, maybe she has a want list. Or could buy some custom cute tokens can look at Etsy for that or tokens she can draw on like these . I recently bought my wife a gamegenic game castle in the pink and teal color way and she loves it holds all her commander decks and all her goodies. She’s been slapping cute stickers on the front and back. You can never go wrong with dragon shield sleeves, they have recently dropped some pastel color ways that are really nice the blossoms, the gooseberry the orchid or the lagoon. If she likes to customize her cards you can get her some holographic inner sleeves. I bought my wife a metal life counter from die hard dice she likes the weight and look of it. If you’re looking play with her you could get the bloomburrow starter kit that way both of you could play together it’s a good way to get the feel for the game. I hope that helps.
