Sky Archtree

Using ONLY SKYBLOCK i intend on creating a giant tree, and all legitimately too
i am doing it alone in singleplayer...(forever alone)
eventually when minecraft 1.4 comes out, i will have access to almost every item in the game thanks to villagers and witches, which is planned in my blue prints.
it is planned around 1.4 in mind so it is gunna take a long, long time.________________________________________

The inspiration is drawn from demon's souls old monk, and a dark souls archtree.
it will have multiple layers, with an npc village(once 1.4 comes out with the abilities to make villagers out of zombies)
as a prison. a spleef arena, library, mob trap... etc

----------------------------------------------------------------------
i did all of this without hacking, i would tape my mouse down to get stone while i ate a sandwiche or did something else, iron ingots drop from zombies, which i use to make shears for the leaves, which i am saving for the roof

Additional Notes

lastly i have plans to try and get a blaze to spawn.
i have no idea how i will, yet, but i have a world set around testing where blazes can spawn, even using the extra buggy top of the world spawns, as in skyblock adminium doesn't exist at the top layer, which makes it possible.
