Sure but as far as I can tell the only must have players on the team are Aleksi, Serjei and Allu.
Decide who you want but Sunny would be a huge fragging upgrade over Aerial or Xseven. He's obviously got relationships with players already on the team as well.
And in modern CS you basically need 3 fraggers to compete at the highest level. Sunny, Allu and Serjei would mean that Ence would have a chance at least to pop heads at a super high level.
I mean you look at the most dominant teams over the last three years you've had four cores (Guardian, Rain, Niko) (Dupreeh, Magisk, Device) (Twistzz, NAF, Elige) and (Fer, Fallen, Coldzera).
The formula since 2016 has been quite clear to me anyway.
