W: Underground Sea H: Goyf, Trop, Cavern, Fetches

I want to switch my legacy deck around, and am looking to get an underground sea.
I would love to do something like my trop + things or cash. Would also be happy to trade a FS Goyf + things/cash.
If anyone has any interest in something like that please start up a trade.

I actually opened up my inventory for once. Take a peek:
