Assume that I have Heroes and Legends objective on table and not focused.
Assume I'm holding Kyle Katarn in hand and have another copy in discard pile.
I play Unfinished Business to return Kyle Katarn from discard pile into play until end of phase.
I focus Heroes and Legends objective to "bounce" the Kyle (which entered play from discard pile via Unfinished Business) and play the "fresh" Kyle from my hand.
What happens at end of phase? Does the "fresh" Kyle still get discarded?
Would this question have been different if I would have used two distinct copies of the same character such as Luke Skywalker from different objective sets?
