Artifact Creature — Gnome

When Cartographer's Companion enters the battlefield, create a Map token. (It's an artifact with "{1}, {T}, Sacrifice this artifact: Target creature you control explores. Activate only as a sorcery.")

Ever since the Fomori's attempt long ago to extinguish Chimil's light, the Oltec have taken extensive measures to never get lost in the Core.
