@Topical_Island I don't think zuran orb is good for the deck as it really wants to get null rod out to shut off moxen in tandem with destroying their lands and sphere effects. The combo is a secondary part of the deck and only something you focus on once you've established control, I feel like this deck should focus on locking out the opponent of mana and then ride it's incremental advantages to victory. you don't need to go infinite, once you have crucible lock and spheres recurring barbarian ring every turn will be enough.
However I feel like the list I was testing was a little too vulnerable to non creature permanents, as it has no way of removing them. I was thinking maybe 1-2 copies of smokestack would be an option, seeing as it synergizes perfectly with the deck and can help you interact with permanents like rest in peace, pithing needle or oath of druids. I think Decay would be a stretch with the manabase. Nature's claim in the sideboard might be better as well.
Overall this kind of deck reminds me of welder UBA stax. A real prison deck with a draw engine that can be absolutely fantastic with the right draws but has some real consistency issues.
So PLEASE DCI unrestrict fastbond it's not degenerate, a ton of fun and it adds diversity to the format since it's not strictly worse nor strictly better than current prison decks.
