prismarine tools and ore

i've seen both of these ideas posted before, but not together. basically, I think it would be cool if players could find prismarine ore in the oceans, an ore that drops prismarine shards when mined (obviously). and then, prismarine shards could be crafted into prismarine pickaxes, swords, shovels, and hoes. swords could be as effective as netherite, but only against underwater mobs, but that might be to powerful idk. prismarine pickaxes could let the player mine underwater without being slowed down, and so could the shovel. the hoe could maybe be used to turn sand into tilled or plowed sand so that the player could farm kelp or coral or something.

prismarine armor sounds cool, but it may be unnecessary. if added, it could allow the player to walk on the ocean floor, and swim back up by holding the jump button. or maybe it could compliment the turtle shell helmet by giving the player more air bubbles.

anyway, this would make underwater building, fighting, and mining a lot easier, and also make ocean monuments more useful.
