It has allowed for some particularly crazy games, especially if you get Rakdos in play early
First, my take on Mardu Reanimtor, which has a very different philosophy from Storytimes: Creatures (22) 4 Imperial Recruiter 1 Ashen Rider 4 Seasoned Pyromancer 1 Skyclave Apparition 4 Grief 4 Priest of Fell Rites 1 Young Necromancer 2 Archon of Cruelty 1 Vile Entomber Lands (22) Spells (16) This plays a more value-oriented, disruptive game than Storytimes take on Reanimator
Theres even a much clearer commander in the form of Rhys the Redeemed, but it seems like Wizards wanted to go with commanders that are inexpensive
1RWU: Target opponent gains control of target permanent that you control
It also has Ward, meaning it cannot be chosen or targeted by actions, abilities, or items, leaving your only option to get rid of it being a good old-fashioned challenge
