Lol! Elf, I love your imaginary entry!
Anyhow, I have the deck right now, and have been using it since Saturday. But of course, I haven't actually started on my One Deck Wonder year. I'll be starting on Halloween, you see.
I'm not sure what I would have done if I received the traveling deck during my year of deck monogamy. How strict do you want to be with yourself and your deck usage? Do you want to be strict vegetarians, so to speak, or are you willing to eat turkey on Thanksgiving.
I think that the deck already has such great energy, it would be a shame to miss out on sharing in that.
Perhaps, if you didn't want to "cheat" on your one deck wonder decks, you could use the traveling deck for non-reading purposes? While I've used the deck for reading, I also used it for meditation, and I gave my little brother a few lessons in tarot-reading with the deck. Those lessons mostly involved story telling and talking about the imagry, rather than reading the cards.
