Is there an easy way to search for lands that provide specific colours of mana?

I figured I didn't need to include "on deckbox" in my post, but zi emeant in my inventory on this site...

I linked Metamox because Deckbox does not have a functionality like that.

It's not perfect, but you can make the filtering work for you:

On rules text you can use {W}, {U}, {B}, {R}, {G}, {C} to represent mana symbols.
Set the Type filter to Land and then you can play around with the text to find the lands you are looking for.

For example, here is a search for all UB lands https://deckbox.org/games/mtg/cards?f=27QWRkIHtVfSBvciB7Qn0*!335. Notice how Underground Sea is missing though? Some lands on Deckbox are missing the rules text to search on so this is why you might want to use Metamox.

EDIT: Now that I'm playing around with this, it looks like {1},{2}, etc. also work for colorless lands that haven't been updated to use the new colorless mana symbol. For example, here is a search for all lands that add {2} to your mana pool: https://deckbox.org/games/mtg/cards?f=27QWRkIHsyfQ**!335.

EDIT 2: I'm continuing to discover more keywords: Use {tap} and {untap} for their respective symbols.

Thanks Avon, that's really helpful - I figured there'd be some sort of shorthand for mana symbols like that but i couldn't find it...
