Currently the playing card wiki links to heart, spade, clubs, and diamond (shape) to be used for the four different card suits but since we also have the tags hearts (playing card), spades (playing card), clubs (playing card) and diamonds (playing card) it feels like it would be better to make these the primary tags for the sake of consistency and to avoid lumping them together with everything else, since clubs and spade are ambiguous tags and heart and diamond (shape) covers so much else.
If we go this way the first two can be aliased over but the last two will need some manual sorting through.
