personally i think its gonna be mouz, not mates. this is mainly due to region representation in vct emea
spain: gx, th
france: vit, kc
north//east: fnc, navi, tl
turkey: bbl, fut
dach: 0
also they dont really seem to care about mena so i think theyre out, especially since the falcons roster got dropped a while ago
mouz is pretty easily the best team in germany imo (at least the most consistent one), so i think theyre pretty primed for vct membership. this would help vct a lot, because it would be a home court team, which brings in more live viewership (theyre already in germany, and germans probably will support a german team more than an extranational one), as well as more german online viewers, so its a win-win imo.
mates, on the other hand, dont really bring anything new to the table. france already has 2 teams, and riot has eyes and can see how shit mates are generally (ban goked from val instead of the team). this also rules out joblife for me because theyre also french.
a second choice would be enterprise. good team, good economic base, lots of fans (as far as i can tell at least). This comes at a downside of adding yet another northeast team, but its a pretty big region so they probably dont care.
tldr mouz (and enterprise) are interesting and mates wouldnt provide much value to the circuit
