If Graaz loses its abilities for some reason, then Juggernauts you control will not have to attack each combat and will be able to be blocked by Walls. However, due to how continuous effects are applied in layers, other creatures you control will continue to be 5/3 Juggernauts in addition to their other types. Unstoppable, indeed!
