By themselves they are all terrible but each one you add is like a buff to eachother.
nrg demon is worse than lev demon1 now that he has com, eg jawgemo had more highlights because he still had potter. every player or coach you add from the eg team is like a 10% buff to all the others until you get all 7 of them, then you get a super team. Lev are trying to use the minimum amount of eg players to buff demon1 to be world class again but com isnt enough they are at like 40% power rn
