How it works:
People submit their best works in this thread, and at the end of each month staff will decide who is worthy of being that month's champion. The person that receives that title keeps it forever, that is unless they go inactive for over 6 months. This rules out other players trying to better you like observed with the previous Champion Hall system.
What's so good about a champion?:
Well, if you're a champion you get some pretty cool perks. You get a place in the new Champion Hall building which is located under the pagoda at the end of the river, or by typing /warp champions. Here you can stand amongst others akin. You also get 8 cards that are exclusive to you and well, see for yourself.

Great, how do I become a Champion?
In order to participate you must post your in-game name, build coordinates and screenshots of your creation. (2 minimum, 3 maximum.) The staff will then decide if you're a worthy candidate and you may find yourself a champion at the end of the month.
Good luck, and have fun.
