In a way, this unit is an slightly improved version of Dudley Dan. Dan's boost can grant you a new unit, even if the attack fails, the down side is that it cost a counter blast of two, and he could only use it if he's supporting the vanguard. Mason, on the other hand, can use his effect from anywhere in the front row, and he only requires a counterblast of one plus the card in your hand that you chose to send to the soul, a cost that is shared by both units. Mason does have to deal damage to get his ability to work, but if he does fail, he's a grade two who can still intercept for you, unlike Dan in the back row.
