Best red green dragon cards?

Yello! I’m super new to magic and have been playing for a few weeks with a Draconic Destruction Commander Deck my bestie bought me. It’s a green and red deck with mostly dragon cards. Wanted to try swapping some of the cards out to customize the deck a bit (not ready to make a whole custom deck yet lmao). any suggestions people think are cool that aren’t crazy pricey?
