Buy 7 or 8 3* players with one position and no special ability. Give them training for another position just to keep them at that level of stars. Keep the strongest 7 or 8 players that you have. On your first day check your cup cl/sl opponents. If they are weak, like 60% 70% there is no need to buy 6* players just buy 4* or 5* replacements for your first eleven until you find cheaper 6*. Don't train any player until you have at least 3000 greens. You should focus first on gathering resources, finishing top 4, leveling up your training level, etc. That is the way to manipulate the draw.
