When Topography Tracker enters the battlefield, create a Map token. (It's an artifact with "1, , Sacrifice this artifact: Target creature you control explores. Activate only as a sorcery.")
If a creature you control would explore, instead it explores, then it explores again.
Good thing I'm not afraid of heights.
