102 – I have some questions about the card Old Rivals in Nebula’s nemesis set. When it causes the Gamora…

Yes, players can defend against the attack from Old Rivals. Yes. We discussed this and acknowledged that the rules do not restrict an attacking character and a defending character from being the same character. However, we did agree that if Old Rivals causes the hero or ally Gamora to attack a player, that Gamora is not considered “an enemy” during the attack since she is not a minion or villain, so she’s not a valid target for abilities that target enemies. Yes, so long as the previous rule is followed.
