Easy shulker shell farm

Adil Gamez's build of a Chinese shulker farm design, reworked by TheySix. Fifteen snow golems drive shulkers to duplicate and the offspring are killed and collected automatically, giving well over a thousand shells an hour from a single starting shulker. The build itself is followable, but getting the first shulker seated is the part that costs people hours, and several builders call it the hardest farm they have attempted.

• The item list is missing pieces the creator himself posts in the comments: one armour stand, one flint and steel, 30 snow blocks and 15 pumpkins. Builders add one activator rail on top of that.
• Shulkers always eject southward, so the killing chamber has to be oriented to match or they never slide in. This is the mistake that costs people days.
• Kick the shulker off the rails with an activator rail rather than expecting it to stop by itself.
• If the shulker only teleports instead of duplicating, AFK for three to five minutes before assuming it is broken.
• On 26.2 shulkers commonly get stuck cycling between the boat area and the top layer, which is the most reported failure on that version.
• Flying the shulker in by boat under a happy ghast and dropping it on the second highest roof is far easier than the rail transport shown in the video.
