LogMy opponent and I both had 2 Possessions and 2 Ambassadors.
(This was actually an incredibly interesting game -- I was trying to Transmogrify my Ambassadors away before he could play them. And I even considered not playing my Champion, in hopes of eventually Ambassadoring his things to myself, which Champion prevents. And I think Amb/Amb is by far the better opening than what we did. But I digress. This happened...)
