Thank you for the very sparse prompt, Syserr, as I think I have more freedom with this than with any other prompt. However, I'm going to break it one way and one way only: One single, solitary Effect monster in the Main Deck (you'll see why in a bit).
Anyway, I had ideas for this prompt right out of the gate, because the idea for the big boss Xyz reminded me of Rhongomyniad . . . so I made Rhongo's little brother, who is very different on a functional scale, plus a secondary Xyz monster that literally exists to make losing said boss not instant death for your entire Deck. I also took a lot of ideas from other very gimmicky Xyz Decks- you'll find traces of Geargia and Lyrilusc in here- and made it so that the backrow mostly made up for the lack of effects in most of the Main Deck. I say "most" because, on a functional level, a Deck with a high concentration of Normals is bound to brick like mad, even if most of them are Machine Dupe targets. Your solitary Effect monster is mostly just an enabler to keep your boss going once it actually hits the field with enough Materials to make a difference, and a play extender to actually get it on board in the first place. That said, it's still a very "brick or broke" kind of Deck, where opening up badly can utterly screw you over. This was actually a lot of fun to make, and I'm glad I had the opportunity.
Also, I know that the name is a reference to . . . something or other . . . but I can't be bothered to look it up, and I honestly prefer the freedom that the prompt gives at a very basic surface level.
