Can you apply the effects of Tarot: Magician to the golden knife in Farmer's Delight and the machete in Nether's Delight?

you can already do this with a datapack, simply add "farmersdelight:golden_knife" (or any golden item) to the "tarotcards:items/golden" tag. other tags can be located here.

for more info you can check out datapack with tags.
