Question: can kamigawa flip cards be commanders?
Answer: Can you run the Kamigawa flip cards as commanders? If the pre-flip side is legendary, like [[Homura, Human Ascendant]], you can. If it is not, like [[Budoka Gardener]], you cannot. That said, if you want to run one of the non-legendary flip creatures as your commander, just ask your group if they'd be ok with it.
