Hylia created all of reality , she is the be all , end all of zelda , the alpha and the omega . The fact that there are three different deities from entirely different pantheons tells me that they are less likely to be anywhere near as powerful as Hylia . Also , the master sword gets more powerful according to how evil the being it is fighting is , so you saying that aku is this big bad evil threat only makes it MORE likely that the master sword will work against him . I think you have a critical misunderstanding of what the triforce is , saying he would need that to get the Scotsman ' s sword and then use that in tandem with the master sword to defeat aku ? at that point if link has the triforce it is game over for aku , because the triforce gives omnipotence , it is said to be able to grant any wish , and was created by the three golden godesses who are just parts of hylia who have a solid universe creation feat . So , unless the three gods involved in the creation of Jack ' s sword also have a similar universe creation feat , then they aren ' t as powerful , simple as that .
