Need:

Steam Vents x4
Hallowed Fountain x4
Overgrown Tomb x4
Blood Crypt x4

Any Rav shocklands? I have these:

1 Breeding Pool
3 Godless Shrine
3 Stomping Ground
1 Sacred Foundry

I am interested in your breeding pool and godless shrines

I have a dissension Blood Crypt and interested in your Sphinx's Revelation. Let me know if you find the difference.

I have an original Steam Vents if you can find a way to make up the difference between that and a Bonfire.

I have several original Ravnica shocks (check my trade list). I'd trade them for stuff off my wishlist.
