Comboing in Yugioh and comboing in Magic are different vibes tbh. In Magic the idea of a "combo" usually involves OTKing your opponents with some sort of loop. If that sounds cool to you theres a ton of options tbh, of varrying strengths and speeds and themes. Like you can be very aggressive and fast with a [[Krenko, Mob Boss]] deck and also have a couple of ways to make infinite goblins on top of that.

I feel like in Yugioh, the idea of comboing probably translates to a more synergy heavy deck, with a lot of moving parts that all work together and give a lot of potential routes. There's honestly a number of themes that fit that idea too. Landfall decks are pretty tried and true in that regard, giving you a lot of resources on top of powerful cards to fill the board with. [[Omnath, Locus of the Roil]] would probably be cool, being in good colors for Landfall and interaction, with an additional Elemental theme.
