Need some advice in teaching my girlfriend how to play.

Hey everyone I've been playing yugioh on and off for 20+ years now and have been dating my girlfriend for about 3 and a half. Since master duel came out she's will occasionally watch me play and has a somewhat general ides of how the game works. She has favorite decks and cards (mostly because she like the art) but she doesn't really know how to use them and any time I try to explain how the game works she gets bored and we stop. It's not that I'm overexplaining or anything it's just that yugioh is very complicated now and she loses intrest after trying to explain how madolche combos work.

So I came up with the idea of taking a few decks from each of yugiohs benchmark formats so she can learn the game as the speed of the game evolves. Like I said I was on and off, sometimes off for years. So can someone give me suggestions on formats/decklists that would help her learn the game as we progress to more advanced formats? Like goat format I got it covered but I only kinda know about Edison and have no idea about hat or toss. Let's alone the entire time frame from when pendulums came out to about a year after master rule 4
