Why would you ever spend the time and money to upgrade a Fate Egg?
My comments: it's too big, doesn't balance it's mana consumption well, and basically looks a mess.
Given those cards, I'd trim down to:
Mark of Time
10 Quantum Pillars
4 Quantum Towers
4 Golden Hourglasses
2 Steal
1 Fallen Druid
1 Improved Plague
1 Elite Otyugh
1 Fire Storm
1 Puffer Fish
1 Quintessence
1 Firefly Queen
1 Miracle
1 Electrocutor
1 Empathic Bond
You're still dramatically overtaxing your Time and Life quanta in that deck, but that's pretty standard Rainbow behaviour regardless. Sell those Fate Eggs and use the money to upgrade your Hourglasses!
