Tectonic Edge: If you and your opponent both have Tectonic Edge out with both you and your opponent having four lands, you can activate your Tectonic Edge to destroy theirs with them being unable to destroy any of your lands. The reason for this is that when you activate your Tectonic Edge to destroy theirs you are left with only three lands, so they cannot destroy any of your lands with their Tectonic Edge.
