Tap → Play or draw a site. If you played an earth site, fill a void adjacent to you with Rubble. Tap → Replace an adjacent Rubble with the topmost site of your atlas.
When I play an Earth site using the second ability, do I also place a rubble in an adjacent void?
When I play an Earth site using the first ability, where does the rubble appear?
Does Mirror Realm (copying an earth site), Valley of Delight (choosing earth), or one of the Bloom sites (i.e. Twilight Bloom) count for Geomancer's first ability?
If Geomancer creates a Rubble adjacent to Boulevard of Bones, do they create a skeleton?
