How to duel?

Well, here's an example.

Me: I of [Team Name] shoots [spell name] at [person of opposite team]! (You would just put their username with an @ symbol before it, to like, mention it and stuff. The result would be DarkeCatnip I use you for all of my examples, sorry!)

Other Person: I overpower [spell name shot at this person] with [more powerful spell].

Is it complicated? I hope not.

Also, be reasonable. Stupefy can't overpower Petrificus Totalus, however, vice versa could happen. Beating someone gains you five points, which you then comment (along with your house) on the "House Points" chapter. You would do that saying:

Other Person: I earned five points for [insert house name].

So now you may ask: what's the point of teams? There is none! You can gang up on others, have backup people... Yep, that's basically it. Besides, who doesn't like teams?

Also, if you think I'm going to post all the spells in existence up here, you are sadly mistaken. That's what Wikipedia is for. And, you know, basic knowledge of Harry Potter.

No use of Unforgivables! Any use will take away five house points.
