When it comes to magic, there's no one greater than Merlin. Too bad the same can't be said for his nephew, who has no focus in his hocus-pocus. Oh, he's got the wand and the cloak all right, but unfortunately Trafalgar uses magic in ways he thinks are hip, even if it creates more problems than solutions. But that hardly worries Trafalgar. He just wants to have fun and sees magic as "the power of cool and my wand is the tool!"
Trafalgar represents the element of determination, an element that he made for himself unlike the other elements in The Elements of Teamwork.
