Magus
The Magi are a group of cycles featuring Human Wizards that reference other cards from Magic's history. Each cycle of Magi copy a different type of card. So far there have been Magi cycles made for Artifacts, Enchantments, Lands, and a fourth cycle that is being made for Sorceries. The Magi Cycles first debuted in the Time Spiral block and were featured in Time Spiral, Planar Chaos, and Future Sight. Since then, a mega-cycle has been made within the Commander sets, releasing another card of the cycle each year.
