Well,
the basic stuff we do in academies, is dueling eachother, having fun, learning from eachother and making decks together.
We also have tournaments from time to time, and on occasion, we can find ourselves in a war with another academy.
Most people join academies to learn from the better players, some join because they like the idea, and some for helping others. But whatever your reason would be to join, it's always a joy to have someone new.
I hope this small but to the point explanation helps you onthe way for academies. And if you have any more questions, you can always ask me.
