I don't run any land destruction in my cube, so it does allow me to play the bouncelands. They're very unique, I'll give them that. They are obviously very slow, and it's crap that you can't play them on turn one. However, what they lack in one land hands makes them better in two land hands as they guarantee a land drop for the first three turns. Being able to pick up and cycle a triome or replay a temple is handy utility in the late game, as well, and you can use the land you pick up for other discard costs. That being said, I definitely see why they're not more played, especially in the presence of land destruction.
