Kitty Kahane is light, fluffy, shrill and pastel-mad. Or do I totally underestimate this deck? Hmm... the jury's still out but I have the feeling Kitty has quite a lot to give.
I guess when I saw Silhouettes first, I thought it's all fluff but I was completely wrong, it's a powerful deck with expressive use of lines, composition and colour. The cute toy look of some figures misled me. So no, it doesn't fit here.
The Harmonious tarot? It looks gentle, beautiful, lovely. In readings, I find it honest and kind, not fluffy either, but tactful is maybe the right word for it.
Another sooting, gentle but very readable and clear deck is Dreaming Way. Like Badgers Forest, it's certainly not fluffy but speaks with a nice, friendly voice.
Among the decks i have, there is no fluff, they're all serious once you take them seriously. Hello Kitty, Gummy bears, what else is out there? I don't have them so I can't say.
