You can create this lineup for 1,000,000 or less! The strategy for creating this lineup is based primarily on the viability of Campus Heroes II 93 Conference Players. These are some of the best set cards in the game currently and are still fairly competitive. In this scenario, someone building this lineup would complete the set of the highest selling 96 CHII Master three times, buying 93s at 80k or less. The goal is to lose only 157k after selling off the master (currently 270k, which would give the player 243k back after auction tax). All other players are bought off the auction house, however, modifications can be made if you prefer to do more sets for BND cards or want to use different cards.
NO SOLO CHALLENGE, FIELD PASS, OR OTHER REWARD PLAYERS WERE USED IN THIS LINEUP
Which means, if you keep up with your solos, the team could potentially be even better. However, for the sake of this post I assume that someone who would want to create this lineup would have exactly 1 million coins and no challenge rewards.
