Feel free to cut the Zeuses, Prosperities, and expensive side-deck cards for budget purposes, and if your locals/play-group doesn't have a lot of people playing Kashtira feel free to cut the Nibiru and Book of Eclipse.
I elected to include Artifacts Unleashed because it can be used to make an Xyz early on your opponent's turn and it can be used as an OTK tool by using it on Artifact Monsters that already attacked during the Battle Phase to make Durendal. It also can benefit you if your opponent recklessly pops it but in game 2 and 3 that will never happen.
D/D/D Marksman King Tell is for D/D/D Deviser King Deus Machinex
Number C101: Silent Honor DARK is for N.As.H Knight
The Super-Poly Engine in the side is for playing against Branded going 2nd but it might have other applications.
Other cards you can play: Call of the Haunted, Back to the Front, Instant Fusion, an Eldlich Engine, an Invoked Engine, a Shaddoll Engine, A Utopia Engine, Generic Link Monsters like Knightmare phoenix and Accesscode Talker, Generic Handtraps, Pot of Extravagance, Pot of Duality, Other Artifact Cards, Board Breakers, and whatever you like!
