Forest of Prosperity (Magic the Gathering)

[Atypical-Abbie]

I had a real time trying to make this work the way I originally intended it, but with some help I think I got it to work that way. If you confused still, this is a list of some cards you can and cannot still use if you want the double green mana:

Sapseep Forest = yes

Rootbound Crag = no

Yavimaya Cradle of Growth = yes (as long as they had no other land type)

Dryad of the Ilysian Grove = no

Desert of the Fervent = yes

Gaea's Cradle = no

Stomping Ground = no

Desert of Prosperity enters the battlefield tapped.
T Add C.
T Add GG. You cannot activate this ability if you control lands that have land types other than Forest or Desert, and only if all lands you control are Forests or Deserts.
