Meat Freezer

So this is a deck I've been developing and testing for a little while. It's been doing ok. Most of my opponents have also been playing shop decks and this doesn't have the best mirror match-up but does well against other things. It uses Eon Hub and Stasis together for a hard lock with Blind Obedience and Tangle Wire for support. Eon Hub prevents Tangle Wire depleting but it also voids the card advantage Dark Confidant provides and keeps Oath from going off. Here's the list followed by some more explanation:

Meat Freezer
Mana:27
1 Black Lotus
1 Sol Ring
1 Mox Pearl
1 Mox Emerald
1 Mox Jet
1 Mox Sapphire
1 Mox Ruby
1 Mox Opal
2 Ancient Tomb
4 Mishra's Workshop
4 City of Brass
2 Gemstone Mine
2 Rishadan Port
1 Tolarian Academy
1 Strip Mine
2 Wasteland
1 Ghost Quarter

Lock Pieces:17
2 Crucible of Worlds
3 Eon Hub
2 Blind Obedience (used to be Root Maze)
3 Stasis
1 In the Eye of Chaos
1 Trinisphere
4 Sphere of Resistance

Aggro/Draw:13
2 Sword of Feast and Famine (Untaps your lands!)
2 Batterskull (Vigilant and can be equipped to Lodestones)
4 Darksteel Sentinel (Vigilant and indestructible. The flash has been relevant too)
4 Lodestone Golem
2 Staff of Nin (underrated card I cut it but added it back for the card advantage and the fact that it kills some very important creatures)

Current Sideboard:15
2 Mindlock Orb (Big Blue and Combo it has a side bonus of messing with fetchlands)
2 Cursed Totem (comes in against Tribal/Hatebear type decks)
2 Nihil Spellbomb (Comes in against Dredge and combo)
1 Scourglass (I think this is an underrated SB card for shops in general. Here it's not as good because of the enchantments but it blows up everything but artifacts/lands so if you're playing MUD you don't lose anything to it. All you need are a couple rainbow lands. If I was playing Metalworker I might try out All is Dust as well. I use this if I'm afraid of falling behind against decks heavy on non-artifact creatures. It also comes in against Dredge and Oath.)
2 Ingot Chewer (Mostly for rods but comes in against shops too)
2 Wispmare (Mostly for Stony)
2 Choke (Comes in against anything that relies on Islands and it is beautiful)
1 In the Eye of Chaos (One maindeck to make hurkyl's and counters a bit harder for game one but one copy is not consistent enough)
1 Sword of Fire and Ice (In case I feel like I need an extra boost toward a deck that's more than Staffs can handle
So thoughts?
