It's not that For example, the Ten of Cups. Crowley hated that card, not because it doesn't mean emotional completion anymore, but because completion is not a fantastic thing to begin with: to him "change is stability", and completion is fixed, static, ultimately just a way to be at odds with the ways of nature: the true completion in the water suit is perhaps the Six of Cups, Pleasure, because it's dynamic.
Thus what the GD still considered a card of perfect and unrivalled success just became "Satiety", a very neutral term, indicating a mechanistic way of filling yourself and then feeling empty, and so on, only because you have a weird idea of being emotionally fulfilled.
if you don't mind me asking, I might be muddled- is your term of emotional completion similar to perfection? I am looking up the meanings for this card and it seems to do with the illusion of perfection and the hunger for it, with the destructive forces of Mars always present to attack this... maybe leading to spoil and excess?
edited to add there seems to be a reference in LMD'S understanding Thoth to this descent being necessary for completion..
