I haven't tried them yet, but can imagine how to play with them. I added a low level (compared to the ones in the cups*) scout buyer (not as low as me with so far at most 1 scout each season), but 4-5 scouts. Maybe I play her in the league, then it could get a very intense season, but I could test your tactics.
* There were people with +5 more quality than my opponent. That is more than one third more than my quality.
@Nordeus: How is this cup based on quality?
In the group stage I have two active managed teams in my group and one abondended team. Their tactics are familar to me, so I expect to pass it. How about your CL group?
