Rules: To start off with 0 mp and work your way up as if you just started. Can sell things in the shop and collect the till, can restock and sell, auctions - all of that stuff. Just can't use any of the money you had before this challenge - it has to stay in the bank.
Note: I am only counting the MP I make from Items that I sell that I received during this challenge. The rest of the mp I will put in the bank if it's not from items I received during this challenge.
