I noticed that a few people have difficulty with the suit domains in 1PSE not providing enough information to work with, so I put together lists of alternative domains for each suit using a few sources (primarily Peach Garden Games’ Carta). 

The final options for each suit were included with Ironsworn specifically in mind, but should work with other systems.

• Hearts (Cups): Water, healing, kindness, emotion, love, or health
• Clubs (Wands): Fire, ambition, courage, movement, growth, creativity, or momentum
• Diamonds (Coins): Earth, stillness, reality, wealth, materiality, or supply
• Spades (Swords): Air, thought, calculation, fear, intellect, trials, or spirit

Hope this helps someone.
