I hope your character actually knows how to use a sword. Swing that thing the wrong way and you get punched through a wall.
Why swing a sword when I could make the ground beneath your feet loosen and make you fall into a hole and make it so its formed perfectly around your head.
Even if you punch me whose to say the wall will be harmful, I too can make it turn into sand for me to fall through and be fine except for the punch you gave me. As long as I have the materials at my disposal I can shape anything into a desired form if of course it's of the same material.

Also I must also ask this but if I am to transmute stuff do I have to be in physical contact with it or can it be more or less be telekinetic is the way that for somethings I can change with my mind but in others I must do with physical contact.
