I selected Elemental of Surprise as my 6 star as Ambassador Faelin, and was on Tavern 5
I bought a 2nd copy of a Smogger and the elemental of surprise in my hand changed to a smogger with 8/8 and divine shield that I could play (Despite it being visually locked in my hand, and non golden).
I sold the smogger on board and was left with 2, non-golden 8/8 smoggers with divine shield in my hand.
I was able to play both, and trigger the battlecry both times. I have screenshots of both on my board, but am unsure how to attach as attempting to attach results in an error.
