Question

When Mister Knife is revealed by Shadow of the Past, does Shadow of the Past gain surge if it was the first treachery revealed by the Star-Lord player that phase?

Answer

No. Mister Knife was not in play when Shadow of the Past was revealed, so his ability does not cause Shadow of the Past to gain surge.
