I've added the Duleep Trophy. This is the first class tournament between the 5 zones. In recent times, the Duleep trophy has been a 2 group affair with a 6th team being invited. In the last three years this team was Sri Lanka A, Zimbabwe BPXI and Bangladesh CBXI. However, given that the original scope of this project will be limited to India, my Duleep Trophy is just going to be a 5-team affair.
