Source ("The basic concept of the "Oasis" cycle stayed. [...] In the final version of the set, these lands played into the pit-fighting element of the story. Each land in this cycle represents a place those fights could happen. In earlier in design, we experimented with not having the lands damage you, but they were too good. We tried having them enter tapped, but it weakened them too much. So, we went with the version that damaged you. [...] These were aimed at competitive play.")
