Pretty easy for me. 3* featured, build up to match 5. Use maxed out 3 stars. Do 10 - 15 matches a day 4* basic, build up to 5 , use maxed out 4 stars. Do 10 -15 matches a day with maxed out teams. Same for the 4* featured but with both rank 4 and rank 5 to always have Thanos teams during the buildup. 5* featured. use my 6 teams of 6 stars to get to 3 million.

Sometimes I drop 2 arena's. Sometimes I do all 4.
