Please this would be good.
In addition to this maybe a legitimate way to aquire enchantments on tools and armor, Potions(alchemy), and a way to acquire new fish, turtles, and dolphins.
Also a way to enter a superflat world and purchase flat plots, in order to make pixel art that can be displayed via vanilla minecraft maps. Could be used to make some very cool posters, paintings, documents, arts, and fliers.
