@Bill2401 You may be underestimating the tendency for you to pick your favourite. Ruby and Yang, who are a perfect fit together given their sisterhood both ended up picking the knight because they have a fondness of horses (Yang because ponies are cute and Ruby likely because of how the piece reminds her of the fairytales she loves). It brought together a dreamer and someone protective enough to care for her when her dreams became too grandiose (single handedly taking down the Deathstalker).

It's soft determination in its subtlest form. Ruby and Yang were likely never going to pick the King, Pawn or Bishop pieces, nor would they likely pick a black piece. Likewise Cardinal likely avoided the knights, rooks and queens. It was likely that Ruby and/or Yang, or someone like Yang or Ruby would pick the White Knight pieces and that they'd be able to spark a sisterly bond.

Interestingly, Blake's first instinct is to grab the black bishop, which likely would've placed her and Yang with Cardin and Russel.
