Cabal StrongholdDominaria - Singles

It does NOT ignore "Urborg, Tomb of Yawgmoth", even though in mono black deck it does. In a B/G deck, Urborg turns your basic Forests into basic Swamps.

And "Cabal Coffers" only really gets interesting with "Urborg, Tomb of Yawgmoth" or late game, the same goes for Cabal Stronghold though.

Now in mono black EDH: cabal coffers+thespian stage+vesuva+this=insane mana

A fixed "Cabal Coffers". WotC overdid it a bit: You need at least 5 basic Swamps in play before this becomes remotely interesting. The 3 Mana activation cost is too high while it only counts basic Swamps.
It ignores "Urborg, Tomb of Yawgmoth"!
