Ok, so I have a [The Twelfth Doctor] deck with [Clara Oswald] as the partner and I was wondering how the ruling on a combo I was planning would go. My goal was to play [Phage, the Untouchable] from exile and demonstrate twice because of the Doctors ability and Clara double the trigger copying it and giving it to two of my opponents, causing them to loose and then tap [Obeka, Brute Chronologist] before my copies resolve.

Is that possible? I don't know how the interaction with demonstrate would put the triggers onto the stack.
