NEEDS "SozoKa's Custom Crafter" TO WORK ! (because else, you will not be able to craft the spawners...)
https://www.curseforge.com/minecraft/customization/sozokas-custom-crafter
This datapack allows you to get the cores of the spawners and to craft them in the SozoKa's Custom Crafter.
You can break the spawner with anything you want and this work only for the 7 natural vanilla spawning spawners. (Zombie, Skeleton, Spider, Cave Spider, Blaze, Silver Fish, Magma Cube)
To know the crafts, just run the command /trigger spawner_help set 1 ingame.
The datapack will only be updated for [1.16.2+] !
