SkyBlock map on minecraft 1.16.4 (probably work on newer versions) with almoste every item in shop. There are 4 islands: setting island with every needed command in skyblock, end island with portal to End, shop island with scoreboard settings and shop, and the last main island where your journay begins. Map will be updated with new items and better datapacks in the future.

Edit: Map was created in void so mobs didnt spawn. So i reupload map with swapped biome by worldedit. Now everythink should work for 100%.
