Some interesting pairs I've come across...
Temperance + Five of Pentacles (As I was trying to interpret a dream no less!)
Ten of Pentacles + Queen of Swords
Ten of Swords + Tower (Since the first word that came into my mind when I drew the Tower for clarification was "epiphany" I still believe this means a sudden realization will cause them to cut off and leave behind a piece of themself, but that has yet to pass...)
Three of Cups + Five of Cups (There's something significant in the RWS symbolism of three cups being held up in the first card and three cups being overturned in the second, but their meaning still escapes me...)
