VIRTUALLY UNLIMITED MOB HEADS/STORM!!!!!!!!!!!!!!!!!!!!!!

With this farm, you can get virtually unlimited mob heads in a single thunderstorm!!!!!!!!! Even getting piglin heads is made very very easy!!!!!!!!!!! Not difficult to build (hardest part is linking nether and overworld sides, but guides are in the schematics). Build the nether side first, placing the schematic so that the blue wool pillar is located at the in-chunk X coordinate 9. When done building, you should place 9 minecarts in each dispenser at the beginning of the railways. Then, go to the overworld and place the mob spawning tower schematic so that the taller tower's nether portal is linked perfectly (X and Z wise) to the blue wool pillar in the nether. The water should be at sea level. Then, load the overworld side schematic and line up the jigsaw block with the other jigsaw block in the spawning tower schematic. You have to place 3 boats in the hopper minecart inside the waterlogged leaves block. Inside the droppers facing the portals, fill it up with junk items. Also, load the dispenser facing the right-side water scaffolding room with healing or regeneration potions. To use: First, in the nether side, load the upper barrels on both sides with items. The number of items equals the number of creepers/mobs you want. You can upgrade the barrels to double chests to get up to 3456 mob heads per storm (or flick the lever to go unlimited, not recommended). Once you load the barrels, the minecarts will start circulating. Then, go to the overworld and AFK on the upper platform, under the solid blocks. The farm spawns around 1200 creepers and 1200 mixed mobs per hour. Once you waited long enough, press the button beside the right portal. The mobs should enter the water chambers. A lag spike is normal. Once the mobs are in, dispense healing or regeneration potions on the creepers. Then, press the button beside the lightning rod to expose it to the sky. Now, wait for a thunderstorm. Once a thunderstorm happens, you can either throw a channeling trident at the lightning rod or wait for lightning to strike naturally. You can AFK there for a storm. Once the creepers are charged, enable the feed switch. Then, go down, press "release mobs", enable auto head farming, and stand on the trapdoor near the killing chamber. You can hold a shield up against the opening to prevent all damage, or use a regeneration beacon and resistance 2 beacon. I will eventually make a tutorial for this farm.
