Autobot

Autobot is a silver-bordered creature type used on a card that depicts Grimlock, a sentient mechanical self-configuring modular robotic lifeform from the planet Cybertron.

The creature type was used for the 2017 HASCON promo Grimlock, Dinobot Leader, which was a mashup of Magic and Transformers (another HASBRO brand). The similar non-legal Heroes of the Realm card Optimus Prime, Inspiring Leader (based on the same brand) uses autobot as a supertype, and the shortened Bot a creature type.
