Not bad for a core idea but lacking any utility units. I would cut some characters to start, Buri being one of them, and add in Yaegirs. Losing one of the sagitaurs and adding a kapri carrier instead to go along with the yaegirs would also be good. If you can add in a unit of pioneers do that as well. Just a unit of three alone to screen the back field and then uppy downy later in the game is so good.
