New Use for the Dragon Egg and the Resurgence of Ancient Creatures

Today we know that the dragon hatched from a dragon egg is something that everyone asks for, but I propose a new use for it: the mystical incubator. By combining a dragon egg crafting in the center, diamond-shaped glass shards, and redstone at each corner, you would create an incubator, which could be fueled with blaze powder... In this incubator, you could add fragments of mythical creatures from Minecraft's past, requiring the player to explore structures to obtain a fragment of a specific creature. For example, while exploring the Nether, you could rarely find a phoenix fragment, such as a feather. When used in the incubator with several blaze powders, after a long time, a phoenix egg would be generated. However, this egg could only be hatched in the spawner of one of the Dungeons located in caves. It would be like clicking a mob egg in the spawner, but in these cases, the phoenix would begin to hatch slowly, surrounded by light. Once hatched and grown, you could tame it and fly it around the world or the Nether, which would be a useful tool. Instead of elytra, there are happy ghasts, but they are slow and fragile. Flying in the Nether. And this could be just one of the creatures from the past; there could be griffins, Krakens, and all of them could serve as mounts. The location of the mob spawner could be themed... From the phoenix to the Nether, from the griffin in the caves, to the Kraken in the sea.
