"Butterfly of doom" or some such. "King Moth" might work. "Slake Moth" would drive some people, running and skittering, from the fortune-teller's booth.

I remember with nostalgia the beautiful Mage-sque major arcana tarot as created by an old mate of mine, and the regret that I have no idea where it is any more. Sigh.

Don't forget to add a yellow sign, or at the very least some sort of jaundiced marionette, to the mix. And "Ask Again Later" might be appropriate.
