Add Tag Hierarchies / Sub Tags.
For example, allow us to expand Card Advantage to see which are draw, impulse draw, self-mill, repeatable draw, etc. Expand Removal into creature removal, artifact removal, destroy vs exile, etc. - Hitzel#4158


Not sure exactly how to link properly, but I just made a post for a graph to show this kind of breakdown, along with a suggestion of how it might be implemented: https://moxfield.nolt.io/1208 :)
I’m glad this exists, I can to request it and found that it’s already been suggested.
My idea for implementation would be to treat tags as fully qualified, but have some character signifier that makes them hierarchical. Tags could then be expanded and collapsed as the viewer wants. This should also allow for staggered hierarchies
E.g.
#!Ramp/Dork
#!Ramp/Spell/Land
#!Ramp/Spell/Ritual
#!Ramp/Rock
#!Ramp/Rock/Signet
#!Ramp/Rock/Talisman
Cards would show under the tag Ramp, but if this is expanded they show respectively under
Ramp
Ramp/Dork
Ramp/Spell
Ramp/Rock
And then if Rock were to be expanded the list would show
Ramp
Ramp/Dork
Ramp/Spell
Ramp/Rock
Ramp/Rock/Signet
Ramp/Rock/Talisman

Recently heard of something that could be useful for this: Scryfall Tagger. It might be a bit overkill for what would be useful for Moxfield, but could be worth a look nonetheless: https://tagger.scryfall.com/
Integration with Scryfall tagger would slap
This would be an awesome feature! Subcategories of tags are sweet
Any updates on this? Would be such a great feature.
