The Connolly Tarot is a set of 78 pretty vibrant and vivid cards. They have kinder and gentler tarot images with Christian influence. The author has also toned down two scary cards in the deck: Death is now Transition and the Devil is Materialism.
For the most part, the letters follow the Rider-Waite-Smith example, but there are some significant differences. Death has become the transition, showing a man exiting a dark building toward an outside exit. I think this detracts from the power on demand, but at the same time, this particular representation is good for those who may be intimidated by more traditional symbolism.
The same is true of the devil, who has been replaced by materialism. A man chained to the representations of the elements. However, the potential significance of the cards narrows. Still, the changes aren't too important
