This isn't entirely relevant, but it's close.
This was a thread I started a while ago about a U/R lattice prison deck.
You'll find that Null Rod + Lattice means that you need to have a creature on the board or you'll simply lock the board position with only 2 win conditions in your deck. I would up the count of Myr Enforcers by 2 and drop the Sundering Titans.
Also, without blue, your draw is so minimal that you'll have trouble getting your Lattice and getting it to resolve. The deck allows the opponent too much time to develop and get situated. If they drop a welder first, you're going to be pretty hosed as you don't have any removal for them except for the cores and firestorm (and firestorm hurts you more with your already minimal draw) . You need something for earlier in the game.
Just a couple of thoughts. Hope it helps.
