[H] CIty of Traitors, Cavern of Souls, MUD / [W] U.Sea, Duals

Have a complete Legacy MUD deck that I'm taking apart if the price is right - 4x City of Traitors, 4x Cavern of Souls, 4x Grim Monolith, 4x Metalworker, 4x Chalice of the Void. 

Looking for RL cards first and foremost, particularly U.Seas or other Blue duals.  Extremely interested in a Tabernacle and would add to this list if necessary from my inventory to make that happen.  Either of those cards notwithstanding, make me an offer!
