Everything Renewable

Does it bother you that some things in Minecraft aren't renewable? That the only way to get more sponges is by plundering more and more of the world? Are your dreams haunted by the looming prospect of running out of deepslate?

Well, look no further! This pack makes everything renewable. Hence the name.

By "everything", I mean every item that can be obtained (in the inventory) in vanilla survival mode without commands. Sorry, reinforced deepslate enjoyers.

Changes

• Tuff, calcite, tall grass, large ferns, spore blossoms, and sponges may be offered by wandering traders. (Each of these offers has a random chance of being added to a trader after it spawns.)
• Tall grass and large ferns can be obtained by breaking their bottom half with shears.
• Dead bushes can be smelted from peonies, lilacs, or rose bushes.
• Suspicious gravel and suspicious sand can be duplicated by crafting them together with gravel or sand. (Note that player-placed suspicious blocks don't drop goodies when brushed.)
• Two raw copper, raw iron, or raw gold can be crafted with a piece of flint and two copper, iron, or gold ingots.
• Deepslate can be smelted from smooth stone.
• Coal, iron, gold, diamond, lapis lazuli, and emerald ores can be crafted from four coal, raw iron, raw gold, diamonds, lapis blocks, or emeralds and five stone. Copper ore can be crafted from two raw copper blocks, two raw copper, and five stone. Redstone ore can be crafted from one redstone block and eight stone.
• All deepslate ores can be crafted in the same way as their ordinary counterparts, using deepslate instead of stone.
• Nether gold ore and Nether quartz ore can be crafted from four raw gold or quartz and five netherrack.
• Two calcite can be crafted from two dripstone blocks and two pieces of quartz.
• Four netherrack can be crafted from two nether wart blocks and two deepslate.
• Gilded blackstone can be crafted from one blackstone and eight gold nuggets.
• Copper, iron, gold, and diamond horse armor can be crafted from six ingots (or diamonds) in an 'h' shape and a saddle in the bottom-center.
• All nautilus armor can be crafted: The recipe is like a chestplate with a bottom corner missing and a saddle in the top-center.
• All pottery sherds can be dug up by sniffers (rarely) or given as gifts by mason villagers. In either case, the available sherds depend on the biome. In biomes without archeological structures, the trial chamber sherds (flow, guster, scrape) are given instead.
• Enchanted books—including ones with Swift Sneak or Wind Burst—can be given as gifts by librarian villagers.
• All banner patterns can be copied onto blank paper in the crafting grid. (See note below)
• Any music disc can be copied onto another disc in the crafting grid. The disc on the bottom is the template to copy; the one on top will be overwritten. (See note below)
• Nine disc fragments can be crafted from music disc "5".
• Eight echo shards can be crafted from a sculk catalyst and eight amethyst shards.
• An enchanted golden apple can be crafted from a golden apple, four blocks of gold, and four diamonds.
• An Ender Dragon drops a dragon head and a pair of elytra, and it has a 1⁄5 chance of dropping a dragon egg.
• A Wither drops either some diamonds or one ancient debris on death (in addition to the Nether star).
• A heart of the sea can be crafted from a Nether star and four buckets of fish: one cod, one salmon, one tropical fish, and one pufferfish.
• A heavy core can be crafted from a Nether star and eight obsidian.

Note: The crafting output will only show one of the copied item. This is a limitation of the datapack system: A crafting recipe can't output more than one non-stackable item. So instead there's a hidden advancement, triggered by using the crafting recipe, which rewards you with the second copy.
