I'll start: Cu Alter - Jalter - Asterios. This team is great for beginners for a few reasons.

Let's start with the pros:
Firstly, Jalter is a lot of people's waifu and Cu Alter is also a lot of people's husbando. Last but not least, Asterios is a precious cinnamon roll. Believe in the Power of Love, and it shall prevail.

Secondly, all 3 of them come with big, red, Buster numbers. Big numbers mean you can whack your opponent harder and I still haven't even started on Chains. BUSTER FOREVER.

Thirdly, throwing Buster Chains are much more straightforward than stacking Arts Chains or baiting your opponent into attacking a Quick Chain, with +3 on that battle. The number of Busters in total between the 3 of them is enough for you to throw a Buster Chain most of the time, while using your Quick, then your Arts to move or discard.

Now, the cons:
Firstly, while this isn't specific to this team comp, almost every Buster-centric decks usually follows a certain tempo of big numbers, small numbers. If your opponent managed to attack you when you only have small numbers left, then good luck to you.

Secondly, if your opponent is playing a Quick-centric, or Arts-centric, any combat could just be bait from the opponent to activate their Chains. If your opponent is attacking and unless you are super confident that your big red number is protection against Quick +7 or double Arts +6, you would need to throw away big number to protect yourself. Which leads back to the first problem. Sometimes running away is the better choice.
