Clone the Magic

Normal Sudoku rules apply. There are three magic squares (3x3 regions that all rows, columns and major diagonals sum to 15) cloned (numbers are in the same posions in all three clones) in three of the boxes in the grid, to be determined by the solver. In four of the boxes, the only allowable places for 5 are highlighted blue. Numbers with an X between them sum to 10.
