Also looking at the list you posted more - I assume the Worn Powerstone is just a budgeted version of Sol Ring?
Budget version of Grim Monolith. If you're legally allowed to play with cards like Mana Crypt, Mana Vault and Sol Ring then you should definitely add them. If you can play with 4, add 4. If you can play with 1, add 1. Etc.
Quote from Sinisterroo »Final question on my mind right now, if I were to go above a 60 card deck list akin to what you posted, say with just a few more random eldrazi creatures, would it be worth touching the mana base at all to compensate or no?
I don't advocate playing more than 60 cards. I also don't advocate adding additional expensive spells without also adding lands to compensate. Still, I mostly don't advocate playing more than 60 cards as it decreases your probability of drawing Cloudposts which has a significant impact on the deck's ability to function.
