This thread is one year too early.
I am hoping that Mustafizur will be the replacement for Mashrafee in ODIs, though I doubt he would be of much use in test matches due to lack of express pace (below 140k). His stats suggest that he bowls wicket to wicket with good line and length.
As a "Medium-Fast" bowler he will make a good replacement for Mashrafee next year.
