Laura Tuan's decks are lovely - there are several (and if your friend is in Paris, Librairie L'Inconnu on Rue Cherche-Midi usually has them all - as well as other unusual French decks.)
Two more - Patrick Jeau or the Manouche. OK, Tarotgarden has them - but it's much NICER to get them from France.... and I have to say - cheaper.....
It is just possible they might find you the Tarot Ambre (Magnin - VERY hard to find - and I just saw it in a shop window !) or the Médiéval (Degome and Montangero) which Tarotgarden DON'T have and which I got in the store I mentioned ! I love it !
PS and I would second Le Tarot de l'Ange Liberté.
