Quote 3x Brainstorm
1x Zuran Orb
1x Ivory Tower
1x Mox Diamond
1x Lotus Pedal
1x Mana Crypt
3x Gemstone Mine
2x Mountain
These are bad.
Brainstorm doesn't help without shuffle effects. If you added some fetchlands, then maybe they could stay. Otherwise, replace them.
The lifegain artifacts won't show up consistently, and the diamond, petal, and crypt are just really bad. Land would be better than these mana artifacts.
Gemstine mines and mountains don't work in this deck. Mishra's factories and islands would be better. Also, how about some shivan reefs?
18 lands is nowhere near enough. Even if you replace the 3 bad mana artifacts, you still have only 21 land, and the ring and monolith. You need more than this.
I just noticed that you only have 3x Force of will. Why?
And a few misdirections would be good too.
Why won't you get morphlings? The deck really needs them. You could go 2x morphling, 1x masticore if you want, but don't try to replace them with serendibs, unless you want to make a U/R IBZ deck.
