Forgive my ignorance, but I have been away too long. I know I have 130 BPV to buy MMC. But I cannot see the cost of units in Ch. H. What is the cost of a 4-6-7 vs a 4-5-8 for example.
Then you can trade one of the 8-0 leaders for a 9-1.
After that you can roll on the Leader Exchange table. On a roll of 4 or lower you can trade the 9-1 for the indicated leader. However if you roll a 12, the 8-0 will be replaced by a 6+1 leader.
