Make Copper useful

Copper is pretty useless right now. It looks gross, the armor and tools are pointless when you can get iron so easily. My idea would give it a use. BRONZE. You somehow combine copper with iron (maybe by adding a new workbench called the kiln) to make bronze ingots, that you can use to make cool looking armor and tools. You can also, with blocks of bronze, make a chariot that you can connect to a horse for storage or just for looks. Also make a rare structure in deserts called abandoned colosseums that contain fallen gladiators. For bronze, make it feel different from iron rather than simply being stronger. Give bronze its own strengths, weaknesses, and appearance. Bronze armor could have an ancient design, The abandoned colosseums could have broken seats, old weapons, traps, treasure, and hidden rooms. The fallen gladiators could be hostile undead mobs with different weapons and armor. These structures would make deserts more interesting to explore and fit Minecraft’s ancient and mysterious style. Bronze could be used for decorative blocks, statues, doors, and other ancient-looking details, giving builders another material while making copper feel worth collecting.
