Unstabilities!

You may only have one unstability in addition to
your deck unless otherwise stated. Unstabilities
remain in your command zone for the entirety of
the game, and their abilities have Eminence. You cannot move your unstability from the command
zone in any way. Unstabilities cannot be targeted
in any way. Unstability abilities that allow
you to choose cards in your deck may only be
used during deck construction. Each pack
contains one unstability card.
