It's an extremely simple deck. You can just read their cards and get an understanding of how it works. They play all the monsters at 1 except Archfiend at 3, and they play the continuous trap.
So the trap and the main deck monsters are their main endboard pieces, and the fact that they all add themselves back at the end of your opponent's turn means you can just set up every turn.

It's almost kind of like Horus but if Horus had actual interruptions on their monsters and didn't have to just be used as ED material, and also they don't risk losing all followup if the opponent had backrow removal.

Also since it has 2500 attack/def synergy that means it synergizes with some random stuff like Bystials.
