Yep thats right, already a new datapack, and ive got a few more on the way!

This time i bring you deadpool, the merc with a mouth.

Heres how to use it:
Every 20 ferns(Not large ferns) you break, you get a tobacco leaf, craft a cigarette with one tobacco leaf, one paper, and one flint and steel in any order and placement.
Drop the cigarette at your feet to use it Do not place it, you will lose it if you do.
Upon using a cigarette, you catch cancer, once you have cancer you will take damage every so often until you die, if cancer kills you, you lose cancer.
While having cancer, you can throw a book onto a lectern to craft a Weapon X contract, throw the contract on the ground to be cured of cancer and gain your powers!

Once you have powers, place an armor stand wearing full leather gear and throw 4 red dye, 4 black dye, and two iron ingots at it's feet, after a bit the leather armor will become Deadpool's suit and katannas.

To remove your powers simply do /tag @s remove Deadpool
