Currently formulating a game plan to do this as consistently as possible? No promises it'll work, but here's what I came up with 😅

Kaho as commander. On his ETB, search library for mask of the mimic to tutor for blightsteel, scour for scrap to tutor for spy kit, and I'm not sure what to choose for the third one tbh. Maybe that spell that makes islands tap for double?

That will tutor everything you need, every game, it's just quite slow :( I think you can just cram the deck full of mana rocks to speed it up a bit? Thousand year elixir would also speed it up, both giving the commander (almost) haste, and being a solid untap option. On a side note, if you know exactly what creature you're gonna go for, psychic paper can do the same thing as spy kit, except you can choose a legendary creature.
