a few more :)

is:karooland might be nice too in case those come back again
produces:(name of color), for example "produces:r ritual" finds red rituals on scryfall

We now support is:filterland and is:tangoland and is:karoo. is:filter and is:karoo are not supported on Scryfall so we will not support those.

produces is covered by #8613 and #11736 and gets mentions elsewhere too so closing this.
