Mason villager revamp

Since the cave update is being added, I think it’s about time we get a villager for trading away all the mining junk we get. Especially considering we will have more mining materials from this update. Assuming players do more mining from this update, the insane amount of ores you don’t need or want to use will need another use, or for copper blocks, which are super expensive, there has to be a new way to get it. I think there should be an amethyst tier to the mason villager, granting 8 different possible trades, which include 5 copper for an emerald, one that gives a copper block for 2 emeralds, and more. Leave ideas in the comments!
