Separation vs Alhen
Ewin vs Vert
Separation's probably favoured in that matchup, but Alhen has looked really solid against an even tougher slate of opponents (wins over clean, Storm Zone, Giannis, ima and Originality vs xavgb, TDNT, Typh, Rumble, Gray). Plus, if Alhen wins I have a fun post planned for the finals and everyone's already pointed out the fun part about a Separation-Vert finals.
Yeah, I think Vert's gonna win, but I think it's worth pointing out that Ewin literally has the most SV OU sheet wins this year (13), with Attribute, oldspicemike and Fusien all sitting at 12. That's good for 3rd in overall sheet wins this year, behind only Santu (18) and zS (14), and tied with Finchinator. Combine that with hellom/clean/zS/3d/Tace wins (which is honestly probably the strongest set of wins of anyone left here; Vert's beaten clean, JJ09LIE, TDNT, heileone and MRH1102) and you have genuinely one of the most impressive resumes you could write up that's still getting completely overshadowed by their opponent.
