Just so it's easier to see...

3 hourglass is too many for a 30 card deck, IMO... also, if you need to slow the game down a little you could add sundials... it'll give you a chance to get more scarabs out and maybe help you get control of the board...
-3 hourglass
-1 reverse time
-1 nymph
+ 2 eternity (if you have them)
+3 sundial
maybe? I'd give that a shot and see how it works... and go from there...
