How does the nuke interact with Start of Battle Abilities?
This will be clarified if Raynor gets published in M5, but they don't count. SoBs resolve in 'moment 0'. If you've ever played Pillars of Eternity or Baldur's Gate, picture it like those games' 'pause on battle start' setting, except you get to take certain actions while everything is frozen. Since the clock hasn't begun ticking yet, they don't cancel out the nuke.
