This deck can definitely be tweaked. I like it right now. I like the lands and I like the number of spells. There are a lot of other directions you can go.

Courser of Kruphix, Faithless Looting, and Commune with the Gods are some good options.

You could also go down an entirely different Scrying Sheets and Mouth of Ronom-based road. There are options.
Budget Lands… and Spells!

If you’ve noticed that this deck uses a lot of throwaway rares and can be built without fetchlands, I have too.

This deck is pretty budget by Modern standards, and it can be tweaked to be even more budget.

If you’re wondering if you’d get your money's worth, I bet you would. The deck is so much fun and it’s good enough.

If you’re wondering if there’s a good speculation on this deck, I don’t know. Maybe Seismic Assault or Life from the Loam, but it’s possible the whole deck would go up in value. I can imagine this being the type of deck that a lot of players like to have in their backpack so maybe if it takes off as an archetype the whole deck will become more valuable.
