Strongly disagree. As it stands, you are paying 5 quanta to *break even* the turn *after* you play the hourglass.
(the first card you draw with the hourglass just gives you what you would have drawn if you had not drawn the hourglass at all)
It has to survive unmolested for two turns and requires a total outlay of 7 quanta to get you to a 1 card advantage.
Sundial, on the other hand, is maybe worth talking about, but not hourglass.
