Set: The Lost Caverns of Ixalan Commander Type: Creature — Merfolk Scout Rarity: Rare Cost: {2}{G} 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.
