If it's XSET-FNATIC: the derke/cryo battle will determine who wins the series. zekken will be instrumental in helping set up cryo to win that battle which will lead XSET to a 2-1 win.
If it's XSET-100T: XSET's mental won't be able to handle to ginormous amount of bang/Derrek clutches as well as Asuna's entrying. I think this is where 100T starts really heating up (if they get here) and carry that momentum to at least the upper bracket finals. 2-1 100T, weeb diff.
