Been on that discord room, it has way too many rooms, honestly, I just felt lost there lol.
I think the biggest problem is that there isnt a focus. Winning money? Ok, but how do you think you can win money out of a collaboration?
First of all all artists must have the same goal and focus, for example, each of you offer a service on a field where you're good at, for example, one might be good at panelling, but cant draw, other might be good at lettering but not at grammar, and so on...
Second, you need something to start from, either an idea, a sketch or anything that provides a clue to where to start working from.
Third, You need to have the ability to meet at certain times for meetings, you need a group of people ready to be committed to a project..
Fourth, start small, try a small project of a few pages to see how things work out.
Fifth, you need to work based on the premise that it'll take some time, sometimes a really long time until some money starts poping out.
Guess those are good advices, use them well.
