Trader golem

Mob idea I think would be really cool and add a use to some other things: The “Trader golem” is a variant of the copper golem that uses an emerald block instead of copper. When it spawns, it’ll spawn with an embedded chest, which is a normal chest but embedded with ores, mostly emerald and iron. The golem is attached to that chest but not any other embedded chests than the one they spawn with. By right clicking the golem, and completing a trade, the golem will sync with that trade and, using the materials in their embedded chest, it will automatically trade with the villager, it will then bring the traded item to a nearby copper chest, for it to be sorted by the copper golem, or if there are none around, it’ll put it in a normal chest. Also gives more use to the crafter, because you can make emerald blocks turn into normal emeralds for trading, or even turning the normal emerald to blocks after trading. The golems can be upgraded with a “trader upgrade” item, crafted with 3 diamonds, 5 emeralds, and 1 lapis block. By right clicking a golem with it, the golem will gain the ability to do 2 trades instead of 1.
