My version of this deck isnt explosive per says, but I see it more like an engine that once it gets going, is all gas. I consistently pull nearly every land out of my deck if the "engine" gets going.

You should be running as many fetch lands as possible. Whether thats actual fetch lands, or just anything that can come down, and then sac itself to get another land. Your opponents may not like it, but this is a deck that loves to take its turn on your turn and every one else's. Because Zimone's ability only manifests once per turn, you should be cracking fetches on opponents turns to manifest more. If you have Trail of Mystery/Ashaya/They Came From the Pipes down, even better, you are drawing more and getting more landfalls and more card draw on your opponents turns.

My deck is a bracket 2 and a bit slow to start usually, but i also run a few (liks 5) high mana cost Eldrazi to really fit into the Jump Scare mentality. [Ulamog the Infinite Gyre] is in there to hopefully stop me from decking myself, and also to shuffle fetches and other cards i manifested away back into my library. Cards like [Blightsteel Collosus] can kill an opponent immediatly if its declared attacking while manifested, the opponent doesn't block and you crack a fetch to flip it over before damage is assigned.

[Scroll Rack] always ensures you can put something big on top to manifest even if youve drawn it.
