Joining MDB boards.

I wish to join two MDB boards. Actually the boards look like MDB and the surfaces are grain printed. I would like to peg the boards but I do not have accurate equipment. I do have a DeWalt slot maker for 2" biscuits. Will MDB boards joined this way be satisfactory mechanically?
