One thing that's helped me engage with my current decks and stop looking for new stimulants is interacting with the Your Readings forum. I get to pull out the decks used by the posters there - if I happen to have them - and use them to help interpret the target cards or spread. These are often decks I haven't taken out in a very long time. If I don't have a deck, I use both the RWS and the Thoth (my standby), honing my experience in combining cards every time.
