A familiar perches on each of your bishops: for the rest of the game your bishops may also step one square straight (up, down, or sideways), finally changing their color.
You draft Twin Familiars in Buff mode. Passive: it works on its own the whole time you hold it, with nothing to activate.
As a movement card, it changes how one of your pieces is allowed to move.
“One for each shoulder.”
Affects your bishops.
