One of the reasons I asked you to repost was because I had the feeling, rightly or wrongly, that you were taking to firm a line on your correspondences. I have strong doubts about the use of correspondences, beyond the simple use as triggers to thought - and a willingness to let that thought turn back on itself and reject or strongly modify the correspondences.
The reason for that is that planet, signs and houses are not tarot cards and for that matter, planets are not houses or signs. I mention houses there, even though you did not raise them in your post, because from an astrological perspective, when considering a question such as this, houses would be vital to the answer.
What I'm about to say, you may see as being negative and unhelpful. However I hope to dispel that impression by following up this post with a second which uses Astrology to answer your question - a branch of Astrology that is known as Horary and existed long before Tarot came to Europe. That doesn't make it any better; I simply say it to show that it, too, has a long and distinguished history.
My first point would be that there's no exclusive set of correspondences. Yes, I know that certain deck designers have 'built in' claimed correspondences for their deck but I'm also aware that readers tend to keep to their own perceptions, even if that means ignoring the designer's intentions. So I make this point general to all decks, whether there are claimed correspondences or not.
Judgement, for example, has been identified with Saturn, Mercury, Virgo, Pisces and Fire. That's a fairly disparate set and it's obviously not exclusive as you have used Pluto and I'm sure there are other viewed correspondences for the card.
The Tower (Maison Dieu) has been identified with Capricorn, Scorpio, Jupiter, Venus, Taurus and Mars. (You have used Mars)
The Wheel of Fortune (base card) has been associated with Mercury and Virgo (by quite a few authors) Mars, Scorpio and Jupiter (which you have used). Again you'll see a spread and note that the same correspondences have already been used for other cards from your draw.
I've never used correspondences for individual Minor Arcana cards, but that's by no means any reason not to do it. There's not really an agreement on elements for suits but, If I remember rightly, Cups tends to be seen as Water (though strictly speaking a cup is a water container - something that I'll come back to again in the reading that I did for this question).
My point here in this post is that correspondences shouldn't be seen as literal equations. Judgement is not Pluto (or Saturn or any of the others); The Tower is not Mars (nor any of the others I mentioned) and the Ten of Clubs is not Mars in Pisces (or anything else.) The correspondences are no more than hooks to start building possible trains of thought.
One final point here before I go on to the reading. You said that you took Pluto and Mars to be in conjunction because they are both Fire Signs. Neither Pluto or Mars is a Sign, they are planets and planets do not carry exclusive element meanings. Mars traditionally rules two signs, Aries; which is a Fire Sign and Scorpio; which is a Water sign. However it can and is able to be placed in any of the twelve.
Pluto, of which I have deep reservations, is associated with Scorpio, which is a Water Sign. It's not an association I would personally make. Pluto is seen by many as destroying the old and replacing it with something entirely new. Again that's not something I would subscribe to; though I'm sure Dave would. I raise the point because you appear to draw your conclusion about Mars square Mars, from Pisces being square to a Fire sign (It does square Sagittarius but it also squares Gemini, which is an Air sign.)
So there's no astrological reason why you should treat Mars and Pluto as being conjunct in your reading and no reason why Mars should be squaring itself. Indeed that is a situation that could only occur if you are comparing two charts - for example a natal chart and the transiting planets at a later date. If you are using the three positions to signify Past, Present and Future, then the latter interpretation would make some sense. The Future bringing whatever Mars signifies into conflict with its present situation/meaning/signification.
I'll post my own reading, for the question 'What should I do?' tomorrow. using the background information that you supplied. I won't attempt to interpret the Tarot cards, merely a horary chart for the question. I hope you will find the answer helpful, not necessarily because it's the 'right' answer but because it stimulates you to consider other possibilities or helps to confirm your own perceptions.
