Minecraft has a lot of blocks, but what if they had more? Why do we need them? Please don't just add lists of things!

I have an idea for a new weapon. If you could add spells and wands to Minecraft, that would be great. The wand and spells could be found in new structures, (like wizard towers) that are SUPER RARE, (both the structure, and the items) with several rarities, the better the rarities, the stronger the effects work. Some spells could be stuff like fireball spells, knockback spells, that knock back all enemies in a 5 block radius, then push them back by 5 blocks, freeze spells, etc. You could be able to apply the spells to the un-craftable wand using either an enchantment table, (spells instead of lapis, which could look a bit like exp orbs) or an alter-esc block, which acts like a crafting table, but looks like an enchantment table. The "alters" could be crafted with 2 diamonds, 5 obsidian, 1 special enchanted book, (which you can choose the name of, for I lack of a name for it), and 1 emerald. You could also make an advancement called "spell-caster" when you first use a spell with your wand. You could get spell book of each spell and right click to actually retrieve the spell, but it cost 5 exp levels to use. (Their could be 5 rarities, common, uncommon, epic, legendary, and mythical, with at least 15 different spells) You could also be able set hot-keys for each spell, which you could change in settings, or, for an alternative, could shift-right click to scroll through your spells, then right click to use the spell, (both while holding the wand, of course, and I would prefer this way) This could be like "a potion with durability."
