Looking to pick up both a Revised Volcanic Island, and Revised Unerground Sea to finish off a legacy Grixis Delver list. Also looking for 2x EMA Force Of Will, and 1x Tempest Wasteland, but these are easier to come by, so not looking to trade the below cards for them, unless as part of a package with the Volc/Usea.
I have the following big ticket items to put towards both:
2x Revised Tundra (SP)
1x Revised Scrubland (SP)
1x Revised Savannah (SP)
1x Rishadan Port (NM)
1x Unopened From The Vault Exiled
1x Expedition Horizon Canopy (NM)
1x Foil MM17 Scalding Tarn (NM)

Obviously I have other cards than this to make up value, or if you have interest in other things, but I figured the majority of these things would be required to get both needed duals. I don't need NM, but definitely looking for minimal wear, so SP or better. Can send pictures of any of the above.

Update - Got the Volc! Still have almost everything mentioned above, only down one of the Tundras. Still looking for the Underground Sea.

For Clarity, I still have:
1x SP Revised Tundra
1x SP Revised Savannah
1x SP Revised Scrubland
1x NM Rishadan Port
1x NM Foil Scalding Tarn
1x Complete FTV Exiled
1x Expedition Horizon Canopy

Update - Now have the following:
1x SP Revised Tundra
1x SP Revised Savannah
1x NM Revised Scrubland
1x SP Revised Scrubland
1x NM Lion's Eye Diamond

And lots of other stuff, but that's the big reserved list items that are most likely to be of interest to someone with an Underground Sea for trade.

Traded my Trop and Savannah up to a Usea. So, now I need to replace the Trop. Still need 2 Force of Wills as well.
Still have:
SP Revised Tundra
SP Revised Scrubland
NM Revised Scrubland
NM Lion's Eye Diamond
NM EMA Jace, the Mind Sculptor
NM Zen Scalding Tarn
and more.

Do you still have the horizon canopy? I have a mint trop I might be willing to trade

The Expedition Canopy is gone, sadly. I have acquired the Trop I needed, but would be in the market to pick up another. I have some other duals available, and a couple normal Canopies that I'd consider trading for it, if any of that interests you. (They aren't showing in my tradelist right now, but you can look at my inventory to see them. Everything but the Trop, Volcs, and Useas would be tradable.)
