I thought I'd found a bug with one of the recently added DMU cards, where a Mono-white card is somehow coded as Gold/Multicolour (White & Black) behind the scenes.
The Affected Card:
DMU # 008 - Benalish Sleeper https://deckbox.org/mtg/Benalish%20Slee
ting=67257
Replication steps:
If you filter by cards in the edition Dominaria United, with the filter 'Colour' set to 'exclusively all of' set to "white", it doesn't show up.
If you then change the filter 'Number of colours' to be 'equals 1', it doesn't show up.
If you then change the filter 'Number of colours' to be '>= 2', it shows up.
If you then change the filter 'Number of colours' to be 'equals 2', it shows up
If you then change the filter 'Colour' to 'is one of' "White", it shows up.
If you then change the filter 'Colour' to 'is one of' to any of Blue, Red, Green, or Colourless, it doesn't show up.
If you then change the filter 'Colour' to 'is one of' "Black", it shows up.
If you then change the filter 'Colour' to 'is all of' and set both "Black" & "White", it shows up.
If you then change the filter 'Colour' to 'is all of' and set any combination of any other two colours, it doesn't show up.
However, I then noticed / remembered its kicker cost. I can see the same behaviour works with the following two cards.
Is this normal behaviour for cards from previous sets with different-coloured kicker cost(s)?
