Like the title says, I have a N/M FoW and I'm interested in a Goyf or Dual of some sort (Tundra?).

LMK if interested

how much value will you add for a tundra?

Depends on the condition. Probably about $25ish? Doesn't have to be a Tundra either. Trop Island, Bayou, and Savannah are probably closer in value if that makes the trade easier.
