Gadianton Lamanite

Ninjutsu (Tap an artifact)
If the tapped artifact was an equipment, equip it
to Gadianton Lamanite. If it was not your artifact,
gain control of it.
..these Gadianton robbers, who were among the Lamanites, did infest the land, insomuch that the inhabitants thereof began to hide up their treasures
in the earth; -Mormon 1:18
