Garbage trader

A villager that is a trader and you can trade with him, not emeralds, but you like trade “trash” into emeralds, like let’s say wood, or idk dirt or stone or so. And the trader like comes in two different forms, that there is one, wandering one with a donkey, and maybe that the trader also like has a house that you can find, like the witches house, but you can find him in all biomes. And that the trader isn’t rare but also isn’t common to find, but he still can spawn in specific areas or so.
