<Snipped quote by Giovanni Carter>

What is the extent of his magic power? Can he make wind blades? Summon tornadoes? Incinerate an entire forest? Simply light a cigarette? Also, you mention the arsenal of blades and their effects. What weapons does he have and what do they do? It's important to declare these things before a fight begins.

Don't leave vague generalities or space for interpretation in your CS, it will lead to arguments later on. State statistics if necessary, or just be as clear as possible as to anything your character can do beyond human capability, which is the assumed average for anything not stated (or required, for example having strong bones if your character has superhuman strength is pretty much a necessity in physics terms.) 

You can use terms such as mid level or low level manipulation of an element, but you'd be expected to keep to that level by whoever you pick as  a judge for ranked matches, so you're at the mercy of someone else' interpretation of your abilities.
