Cyclops

Ravnican cyclopes, also known as monoclons, are spread among the guilds. Most are under the leadership of the Gruul Clans, befitting their violent temperament and savagery. 
The Boros also recruit cyclopes to serve as fortress guardians.
The Izzet League use them for heavy lifting in their laboratories. They also on occasion have experimented on them, with the result being the Nivix Cyclops.
