This seed has two villages, one on the edge of the jungle and the other a short distance away. Both villages have blacksmith shops, and one of them contains your first set of diamonds. Then deep inside the jungle, you can find a jungle temple with even more diamonds in it. Any time a seed has diamonds you don’t have to mine for, it’s worth it.
This seed has a wide range of features worth seeing. It starts off in a taiga with the mega taiga to your right and a swamp to your left. In the swamp, you can find a recluse witch at her witch hut. Then you can find two villages, one on the plains and another in the taiga.
This seed spawns you in a forest, but not far away you can find taiga and extreme hills biomes. Better yet, the taiga contains a village with a blacksmith shop. This seed keeps on giving with a ravine next to the village, and llamas in the extreme hills not far away.
This seed spawns you in a taiga with a village nearby. On the opposite side of the village where you spawned, you can find a ravine with an abandoned mineshaft. In the mineshaft, there are a dungeon and a chest minecart with a diamond. This seed seems to just keep getting better the deeper you go.
Jungles and mega taigas have some of the tallest trees in Minecraft. They also have other features that make them unique and cool to stumble upon. This seed has both of them close to each other so you can enjoy the benefits of both.
