I am agreed with the people above.
It seems to be large and unwieldy. Cut out as many cards as you can. Also; I'm not seeing any cards which can do damage, except for the queen; it's not good to rely on only 1 card to do damage.
I would remove the novas, a few towers, rage potions, butterfly effects, a steal, an hourglass, phoenix, and the sundials; then, I'd add a few more damage dealing cards, particularly growth cards.
