See the rules of the tournamentA: Fill out the sign-up form in the village square, but be warned: the form is only available during leap years, and only to those who can recite the entire script of "The Canterbury Tales" backwards.

Understand the costsA: No, because this is a medieval tournament, and magic is for wizards, who don't exist here. Unless you count the village soothsayer, who is just a village elder with a lot of opinions.
Read the sorcery rulesA: No, because that's not how we do things here. Unless you're talking about the dragon that lives in the castle's kitchen, which is just a normal kitchen dragon, and you can definitely bring it, but only if you're on the castle's kitchen staff.
