There is an inconsistency between the following two cases:
A) None of my creatures have defensive abilities. I give the creature in creature slot two vigilance with Haunted Cloak. I put some Thopter tokens into play, there were none in play before. The creatures re-order themselves so that the creature with vigilance is in slot 1.
B) None of my creatures have defensive abilities. I give the creature in creature slot two vigilance with Haunted Cloak. I put some Thopter tokens into play, reinforcing a stack of Thopters that were already in play. The creatures do not re-order themselves.
That’s one for your Bug Status List, @Brigby
