I'm trying to exchange all my habitatats to those holding 5, so I really don't want to buy more of these for 4, but there aren't any alternatives at the moment. I have bought a lot of Destiny Deltas (for pink) and Arcane Fires (for black) plus a few more Shimmering Shoals (for white) this sale. I bought over 50 of the Fairy Crossroads back when they were on sale for 75 - now that was a good sale, probably won't come back.
My challenge is all the types where there are no large-capacity habitats like Dino, Stone, Soccer and Olympus. Plus a number of special 3- and 4-dragon special habitats received as prizes which I can't bring myself to sell. But I'm quickly running out of space so it will probably very soon be that or quitting
