Rider Waite is the most popular Tarot Card Set. I'm sure you've seen it.
Angelinity's avatar is the fool from that deck.
I however prefer the Albano-Waite deck as it's more vibrant and colorful.(same cards, just retouched, infact I'm pretty sure Angelinity's avatar is from the Albano-Waite version and not the Rider Waite version.)
The Devil would be a good card. It's the card for male sexual energy which is why the "Devil" is depicted, ala Pan, Kernunnos(celtic fertility god), The "Horned One". In some decks I've seen the devil is even depicted with a giant oversized phallus.
the suits are
Disks(Pentacles) - Earth Element - (material matters, monies, home)
Wands - Fire Element - (passions)
Swords - Air Element - (brain, intellect)
Cups - Water Element - (heart, emotions)
Some people don't use "inverted" cards. A big debate exists as to the authenticity of inverting a card, the philosophy is (1. If you stack and shuffle your cards CORRECTLY there won't BE any inverted cards and 2. The tarot cards are so informative as is that there's no such thing as a "dignified" and "ill dignified" version of them....You get what you get positive AND negative qualities )
However many if not most "professional" fortune tellers use the inverted cards. And in that case the lovers inverted is heartbreak, break-up, hatred, spoiled love, negative obscession.
