btw who is your general?

Rust and Bind seem pretty ok. 

Regarding the lands, I wouldn't use the Urza Lands, because they give colorless mana, and Gargoyle Caste doesen't really seem to be wort it. Instead a reliquary tower, to be able to hold more then 7 cards in hand is totally worth it. Also rogue's passage. I would add secluded steppe and tranquil ticket for a possible lategame card advantage

Looked through some lands, here are some that caught my eye:

Edit: Added to sideboard instead.

That sounds like a great way to start improving the deck, any imediate suggestions? I have not used very many non basic lands at all. I had heard once that certain dual lands count as basic lands, but was never able to find this within the comprehensive rules, Any idea there? if not I suppose I could start with picking up some shock lands etc.

Regarding the land base, have you considered running some dual lands or lands with some abilities?

Well ratchet bomb is the least of my worries in that regard. In my playgroup, no one runs ratchet bomb that I know of, and even if they did, anihilator is a bigger worry really. Plus if im lucky enough to have out Eldrazi Monument then its no big deal. Lastly, some of my tokens usually have a cmc. (mimic vat + populate)

I meant that Ratchet Bomb wipes you out...

What about ratchet bomb?
