Multicolor card search filter

Can we have an option to search for multicolor cards, please?

Here's how I'd do it; add an additional toggle option to search for multicolored cards; lets call it MULTICOLOR here.

If you select MULTICOLOR and no other color options, it shows you ALL multicolor cards.

If you select MULTICOLOR and any color options, it shows you all multicolor cards that share a color with those colors selected.

So for example, if you search for MULTICOLOR and white, it'll show all multicolor cards which are part white; if you search for MULTICOLOR and red and black, it'll show all multicolor cards which are part red and black (which would mean, in addition to all 2 color red and black cards, any 3 color cards which are part red and black, e.g. Darigaaz)
