Time to revive an old topic... EmpressBethany and I have created a new public guardian farm which is off Savannah hub. You can get there through the red wing, through the tunnel marked with prismarine shards (Fish Basement tunnel). It has a looting attachment (resistance 2, strength 2, and regeneration included!), as well as a cafe with free food (thorns hurt, you know) and a bunch of mazes you can enjoy!
