The hero of Zelda has on a few occasions used the mystical Four Sword to split himself into four, so that he can cover enough ground to save the world. If the sword didn't exist however, or magic failed us, this is the team of heroes that could take his place.
The reason Link is the one who uses the Four Sword is because he is the best. That said, he has to stay on the team.
The Merc with the Mouth might be a lunatic, but he's a damn good swordsman. With an outrageous healing factor, the ability to teleport, and various other weapon proficiencies; not to mention the ability to quip at any situation; Deadpool has to be one of my 4 swordsmen.
Yeah, he's a bad guy, but he is a swordsman to one hell of a degree. The blade he wields is twice the size of him, yet he never manages to nick himself mid battle. Although a very close eye would need kept on him, he could do well if properly monitored.
As one of the chosen ones of the Charred Council, War is a natural swordsman, as well as automatic member of a team of 4 already. He would know perfectly how to work with 3 others, and wielding his own sword Chaoseater, would be an obvious choice to join my 4 Swordsmen.
