Going second beatdown deck.
Side deck is personal feel free to build it as you want.
Ritual monsters are just good extenders in the deck with situational great impact. You can cut them and the ritual cards for other extenders like backup secretary or balancer lord. If you do don't forget to cut Cyberse with aswell, you would add for example a Cyberse Quantum Dragon.
For budget options you can cut dark ruler for handtraps or disruptions. Acesscode is very expensive but it is the best option we have by far as we are limited to cyberse monsters (due to reborn). You can try with avramax or zeroboros but it won't be as efficient as Accesscode Talker. Cynet Mining is also quite expensive but i think it is mandatory to reduce brick.
