If my Commander is part of a mutate stack, and an opponent casts Leadership Vacuum, where do the non-Commander cards go? And if the other cards do go to the command zone, can I cast them?
They’ll wind up in the command zone and you won’t be able to do anything with them from there. This is unfortunate, but the command zone is a zone like any other and sometimes cards go there that aren’t supposed to be there.
Look on the bright side, though: If any of those creatures have abilities that work from the command zone, such as Yuriko or Derevi or Edgar Markov, those abilities will still work and be usable there even though the cards aren’t your commander.
