Agent of Treachery didn't trigger due to card becoming a copy
I controlled an Agent of Treachery and three cards owned by my opponent. One of the three was transformed in a copy of one of my own cards with Blade of Shared Souls, but was still listed as owned by my opponent on mouseover. No trigger at the end of turn.
The agent triggered as expected once I controlled a fourth permanent owned by my opponent.
