(A2A) The answer to this has changed over the course of history.
In every Tarot deck inspired by the Hermetic Order of the Golden Dawn – including, most importantly, the Rider Waite Deck – Tarot Key 11 is “Justice.” However in every other deck, including every deck devised before the Golden Dawn, Tarot Key 11 is “Strength.”
Confusingly, the Crowley Thoth deck, which undoubtedly is GD-inspired in part, has its equivalent of “Strength,” i.e. “Lust” as number 11, and the counterpart of “Justice,” i.e. “Adjustment” as Key 8. This is not, as some believe, because Crowley was using his ipsissimus super-powers to change the order of these two trumps, he was simply keeping the numbering found in ancient tarot decks.
VIII Adjustment, in the Crowley Thoth Deck. Numbered 8, but nevertheless attributed to Lamed and Libra all the same.
The reason there is any confusion at all is that the GD came up with the idea that if Keys 8 and 11 were Strength and Justice respectively, they would correspond to Leo and Libra, and if you put the Fool at the head of the Tarot Trumps, the whole sequence would qabalistically map onto the 22 letters of the Hebrew alphabet. Hence the innovation was made by the GD in making Justice number 11: Crowley just changed the numbering back – although he did retain the astrological signification.

The Golden Dawn was my entry into occultism generally, and consequently the Tarot as well. Hence Robert Wang’s 
was the first deck I ever bought: it was the one on which I learnt. The trumps struck me as the most impressive, although I confess I thought the art-work was a bit ordinary. Nevertheless this is still my default deck today, the one which I most use for doing readings. I have to admit though that if I were buying a Golden Dawn deck for the first time today, I would probably get 
instead, mainly because the art-work is livelier.

This is not really a Tarot deck per se, more a Cartomancy deck. It is not based upon the traditional Tarot format at all: instead, each card represents a portion of the Enochian Watchtowers and the Tablet of Union. Meanwhile, the reverse of each card instead of having a uniform backing has elemental symbolism (corresponding to the Enochian associations on the obverse side) which can be used in skrying. The meanings of the individual cards take a bit of getting used to, although there is a logic to the general scheme which is based on GD teachings.
Given that the 
I decided to get hold of this after seeing a fellow Tarot reader use this. What I find most appealing is that the creators of this deck have based the artwork on Greek mythology. Hence: the suit of Cups is the story of Cupid and Psyche; Wands is the story of Jason and the Argonauts; whilst the characters in the Major Arcana are identified as Greek gods and goddesses. This is a visually appealing deck because, like the Rider Waite one, all 78 cards are fully illustrated. Also it is refreshing to see a deck which goes with an original idea for a change which comes off successfully.
Of all the Tarot decks which are available, the ones that particularly interest me are those created by Occultists – as opposed to the many which appear to be novelty decks, or created by people with only a superficial understanding of the subject. Hence my reason for being drawn to not only the Golden Dawn, but also the Crowley Thoth, Rider Waite, etc decks. I suppose it was thus inevitable that I would seek out the Builders of the Adytum, given that it was designed by not only an occultist but by an actual Tarot scholar, Paul Foster Case. The thing about the BOTA deck is that it comes uncoloured: the point being that as a student learns about the Tarot, they use their own knowledge of the esoteric associations of colour to colour it in themselves. Unfortunately I discovered that the BOTA deck is very hard to come by on Amazon – with one going for over £100.
This is something of a curiosity which came into my possession, and of which I have not made use since acquiring it. The trumps feature a lot of lurid artwork – dragons, monsters, scantily-clad buxom women, etc – which only vaguely references traditional tarot imagery. Meanwhile the accompanying booklet puts a Vama-marga Tantric spin on interpretation of the cards.
