If Miss Fortune (5 cost) moves with another unit from base to a battlefield and her ability triggers to ready something, can she ready the unit that moved with her so it's ready at the battlefield?

Ruling: Yes, Miss Fortune can ready the unit that moved with her to the battlefield, and that unit will be ready at the battlefield.

Sequence:

  • Exhaust all units being moved together (as the cost of the standard move)
  • Move them all to the destination
  • Resolve any move effects (including Miss Fortune's ready ability)
  • Start a showdown if needed

Nuances:

  • The unit being readied doesn't get readied until after the move is complete, but since all units move together as a group in one action, the readied unit still arrives at the battlefield ready
  • This only works for units moved together with Miss Fortune; you cannot ready an already exhausted unit and have it join the move
