This is a perfect, flexible and adaptable deck that has many moving pieces and parts. The learning curve isn't that hard and once you get the hang of what each engine does, then you will unlock a world of opportunities. A few pieces of advice ;
1. Always try to use imsety last as a search effect because the horus cards are the heart and soul of the deck. You need kings sarcophagus to go off in order to use many of your plays and get a bunch of stuff out of your hand.
2. You can take the bystials out, but they are very handy and resourceful. Best of all you can use the whole engine to recycle extra deck monsters like I:P or galatea by banishing them when they are in the grave and sending them back with the bystial continuous spell
3. The only major lock on the deck is the "dark machine" lock, so you should try and do all your other plays first and only go into orcust effects if you don't have any other special summons
4. Finally, I really, really, really hate skill drain. So, if you want to out cards like skill drain or TCOBO then there is a special tech for that being in the side. Meet the Hieratic sun dragon heliopolis. It can be made with horus cards and can also be recycled by other cards. Best of all, he can tribute himself and other cards to destroy other cards on the field which is the same as access code or dracossack
Overall, it's an amazing deck, and you will have a lot of fun with it.
