Ooh I really don't like keywords, I find them too distracting and find that sitters often focus on the keyword and nothing else. They almost don't here what you're saying because there is a keyword like 'fear' or 'futility' there.
I know that Thorhammer says don't say Thoth but I think the titles on the Crowley Thoth deck are really keywords
.
Other decks that spring to mind:
Glastonbury Tarot,
Waking the Wild Spirit Tarot,
MerryDay Tarot,
Voyager Tarot,
Parrot Tarot,
Navigators of the Mystic Sea,
Osho Zen Tarot
There are loads of them about
