Deck search colors limited

starfall

While build a deck for a planeswalker, the search function is limited to searching for only cards of that planewalkers' color, or colorless. So, for example, when building a deck for Vraska, I can only set the color filter for black, green, and colorless.

But there are multicolored cards in the game! I cannot search for all the white cards that Vraska can play (e.g. Vona, or Arvad, or Conclave Guildmage)
