I don't think anyone has said anything about your reading that was all reversals: that could have happened because you were feeling a lot of self-doubt (about the situation, OR about reading on it).
Personally I don't ask the same question twice. Not without a good amount of time between. I have also given up rephrasing, because I feel that's the same as asking twice and if someone keeps asking me the same thing in different wording, I get fed up.
Besides, as others have said, if we're taking the tarot seriously, you're just making the cards repeat themselves! (I know you're talking about different decks, but still, the way I feel it is "The Tarot" doing the answering - the universe, I suppose.)
I do find that each deck has its own "speciality" kind of question. For example I'm getting to know the Wild Unknown and the Illuminati, and for myself I find the WU wants to talk about me, my level of spiritual health and the home truths that I need to be told, whereas the Illuminati tells me more about others, and about "real world out there" stuff. At the moment, that is - may change by next year.
And every situation has these different angles to it, so if I wanted to keep asking on the same thing, I'd be able to ask the WU what my responsibilities are in the situation or what opportunities it holds if I have the courage to seize them, or what I should be aiming to do, those things... while I could ask Illuminati who I may find blocking my path or being helpful, if there are practical details I haven't thought of, that kind of thing. There are far more questions than "How will XYZ go tomorrow?"
So that's sort of asking the same thing of another deck, but it's more like having conversations about the same thing that's on your mind, with different people. Which we also do when we're considering something. Each occasion of talking it out / reading the cards offers new insight.
Thanks for this thread - got me to clarify something I knew but wasn't aware I knew, something I do but wasn't aware I do!
