unpopular opinion but the aces and falconers aren’t rivals, we just see them as having tension because our view of them is centered around the parse/jack interaction in the comic. there’s also the “typical fucking aces hockey” comment but individual players naturally have opinions about every team and teams also have reputations based on their playing style.
rivalries are almost always geographically-based or at least intra-divisional and las vegas and providence have zero connection that would make this a plausible rivalry
