Goblin

Standing around three feet tall and covered in warty green or red skin, goblins have large noses and ears. Their wiry bodies are surprisingly strong, and their mouths are full of sharp, crooked teeth.
Most goblins are bald, either by heredity or by choice, but a few boast shocks of red or black hair. Their arms and legs are elongated in proportion to their small bodies, and their fingers and toes are also long and slender. Many goblins prefer to go unshod to leave their toes exposed for climbing.
Creatures of raw impulse, goblins are found among guilds that value that quality, particularly the Izzet (where they typically serve as attendants for researchers), the Gruul (in camps that form hapless buffers between the clans and civilized regions), the Rakdos (putting their love of explosions to good use), and occasionally the Boros (if they discover a well of discipline and courage within themselves, or find themselves unable to resist the shininess of Boros weapons and armor). Many goblins are guildless and make their way as members of street gangs.
