You expect to get a single land back with Profound Journey for seven mana? Really?
Try
Planar Birth,
Second Sunrise,
Faith's Reward, etc... significantly better for a fraction of the cost.
You need to be playing
Teferi's Response in this. Card draw, protection and destruction in one...
Cauldron of Souls will repeatedly save your lands making them 2/2's the next time they're animated.
Darksteel Citadel is a must.
Flagstones of Trokair is really good here.
Terra Eternal.
Teferi's Veil swing with your big honking land then they phase out so you don't risk losing lands to sorcery speed removal.
I would suggest
Neurok Stealthsuit to protect your general with the added bonus of instant speed protection of your other creatures/lands. If Noyan dies, you're quickly screwed, especially if you've lost a few lands. He will quickly become uncastable and without him in play you're doing basically nothing.
Your "ramp" cards are rather bad IMO. I'd swap sphere for
Expedition Map and the eye for
Burnished Hart at the very least. You can also use
Knight of the White Orchid and friends to ramp directly into play.
Crucible of Worlds is really important here. If you can afford one it will be a godsend in this deck.
I'd play
Forbid over spell burst or controvert. You should already be able to draw enough cards that discarding a few won't hurt but not enough that you can take over the game with it.
I'd play the new flip jace if you have one. He gives all your spells flashback but you can still pay the buyback to get them back to hand.
Strionic Resonator will give all your spells a +2 for 6 counters effect.
At first glance, your deck is too high curve and not able to recover well from removal/wipes. You're playing too many lands rather than ways to get lands into play or otherwise ramp. You're playing a deck that needs to be able cast spells which requires a lot of mana but the deck also is entirely dependent on having lands as attackers/blockers which means you'll either be left open or left short mana to do anything with the current iteration.
