Drone refers to simple, immature or artificial lifeforms which perform tedious and menial work.
Mirrodin[edit | edit source]
Drones were living yet artificial beings created by the vedalken of Mirrodin as guards, sentries, and shock troops. Though most likely self-aware, they lacked free will, and were mute, unquestioning slaves of the vedalken.
There were two varieties of drone: The land-bound wanderguards patrol the entrances and byways of Lumengrid, using their psychic abilities to scan visitors' minds for unwelcome thoughts. They were tall, squat humanoids with bulbous metallic bodies sprouting spindly limbs, no neck, and a small head with huge unblinking eyes.
More common were the hoverguards, similar in appearance to wanderguards but sprouting enormous gas-filled sacs from their backs that afforded them lighter-than-air flight. Most hoverguards lacked hands, instead having long metallic blades jutting from their wrists. Hoverguards doubled as sentries and taskmasters, the low hum of their inner workings a constant reminder to Lumengrid's Neurok slaves that they were under constant surveillance.
Zendikar[edit | edit source]
Below the colorless Eldrazi of Rise of the Eldrazi are smaller Eldrazi Drones that are aligned with colored mana. Many of these Eldrazi Drones, as well as some spells, produce Eldrazi Spawn creature tokens. These 0/1 colorless creatures can be sacrificed to add to your mana pool—perfect for casting those enormous Eldrazi.
The Eldrazi Drones of Battle for Zendikar, though requiring colored mana to cast, have devoid and are therefore colourless. Some produce Eldrazi Scion creature tokens. These 1/1 colorless creatures can also be sacrificed to add to your mana pool.
