Restore Balance (Modern)

All right, so this is my new restore balance version. Budgetable, for me at least- uses shocks and fetches I already possess, and the only thing in this deck I do not currently own are the Nahiris, which I'm hoping to trade into before friday :)

Last week I was playing with a five color version that utilized as foretold. It's an amazing card, being able to freecast balance from your hand AND, three turns in, basically eliminating the need for you to even have lands or borderposts on the field! However, most games I was playing, it was simply too slow. If I didn't have a balance in hand, or didn't need to cast balance yet, it ended up being a dead turn- moreso because I felt compelled to get it out on turn 3 if possible to let it ramp up to general usefulness. That, and the simple fact of using five colors instead of four, I felt dragged down the deck a bit. That's partly because I don't possess the fetches/shocks to make five colors work reliably- I used terramorphic expanse, evolving wilds, and straight basics, which is extremely doable with borderposts doing the heavy lifting as far as color distribution goes, but often a bit slow.

This deck is more based off of another deck I recently saw and liked very much, credit where credit is due: http://tappedout.net/mtg-decks/greater-borders/

I'm unsure if it's wise for myself to only have 3 balances in my deck. After all, I do not yet possess emrakul to let me shuffle them back from the graveyard into my library, and I've lost a few unlucky games where I drew/used all my balances in the first few turns, giving me only the 5cmc 2-of goblin dark-dwellers as a non-instant cast. I may ditch the dark-dwellers altogether and bump the count up to 4, along with a 1-of Kari Zev's Expertise.

I would love to get some input/suggestions before I finish putting this together in paper on Friday!
