All of my creatures, except my general, disappeared when I attacked
I was playing a game with Ruhan of the Formori as my general. I had three other creatures in play. When I attacked with Ruhan and another creature, ALL of my creatures just disappeared, aside Ruhan. Not to my hand, not to exile or graveyard... They just immediately vanished. Armored Skyhunter's attack trigger was being resolved when they disappeared. I haven't attacked with that card before, so I don't know if that was the cause... Obviously I lost that game :p
Had same issue with Armored skyhunter. all creatures except the equipped creature(my commander) disappeared. not in graveyard, hand, library, exile, neighbors board. gone.
