Its a good fit in lifegain/life drain decks, zombie typal decks, or even Bloomburrow -inspired bat decks that care about gaining and losing life

After all, while sometimes Commander is about optimizing every slot, curving out perfectly, and executing your game plan with ruthless efficiency, other times, it is about winning a game with a pony, his Food, and all the friends he made along the way
Mardu has a lot of access to artifact support, making Jan Jansen, Chaos Crafter a fantastic commander choice for Sacrifice decks in Mardu
