I dunno, looked mostly like you were just running around each other and trading blows, and Tristan happened to lose because of a stupid SD and running into a fully charged upsmash.
Video 2:
Tristan pretty much took the advantage here with the edgeguards. Overall play is still the same, run around and hit each other two or three times, run away...

Both of you are edgeguarding, but it seems Crossjeremiah jumps into the **** (gets his second jump stolen by an edgeguard) a lot more. Still lots of just trading blows. I see a few more attempts to follow up, but mostly once you take the advantage you grab, throw, run away and start charging needles.
