Suggestions for "cool" cards that are also affordable

Can anyone suggest some Pokémon cards that look really cool but are still affordable? I’m trying to find some cards for my 1st grade daughter that she’ll be proud to show off, but I’m really not looking to break the bank on single cards. Also, suggestions that cross over into "Kawaii" instead of "cool" would be equally appreciated.

​Some context: My daughter is finally become a real life individual, and I’ve been buying her the occasional booster pack to share the nostalgia of collecting, but it seems the playground scene has changed since I was a kid. She took her cards to school all excited to trade, but came home crushed because the other kids told her "her cards were trash."

​Apparently, a lot of the kids in her class are going to hobby shops and buying more expensive singles straight from the display cases. I just don't think it's wise or healthy to be dropping $30+ on a single card for a 6-year-old. I am hoping that, for 1st graders, the "rule of cool" still applies, and maybe we could buy her some cool cards that are also still reasonably priced.

so anyways, I'm coming to you guys for suggestions. Even if this is a naive ask, I'd still love to see some "B-Side tracks" of the Pokemon card world. Some of the lesser known or lesser appreciated artwork.
