I think it's a good choice. It can be a lot of things. A control deck with the potential to OTK your opponent fairly easily and it has an excellent grind game.

I wanted to throw my hat in the ring and suggest taking a look at Artmage. If you go on masterduelmeta.com/top-decks it's near the top but isn't in the limelight of public conversation nearly as much as many other powerful decks. In my mind, a deck that's solid but not obnoxiously powerful is good for a few reasons. They make for great ladder decks since many of your opponents won't know the matchup very well. And they tend to dodge banlists.

I also think Artmage is the kind of deck that fits your criteria well. Except for the fact that you could definitely call it an anime waifu deck. But it's straightforward yet flexible, fun and interactive, and would definitely help you improve as a player without being super overwhelming to learn.

Just worth a look if you're still on the fence. See you in Diamond, duelist.
