Yeah i'm available nights this week (Mon/Tues/Wed). From what i've seen in races (haven't played RedScar or Koleax) the 4 should be:

-DeepMix
-IDReaper
-CoatlKetzal
-Rezatron

The only problem is the language barrier with CoatlKetzal, he's not comfortable with English, in that case I don't have a 4th candidate really...
