So... let's list the main problems I see with the deck.
- It requires large amounts of 4 different quanta (

)
- It needs time to set up, but it lacks defenses to do so.
- It needs a number of cards to set up a combo.
- All this has to work unupgraded and without rares you don't have.
It might be hard to solve all of them, but I'll try.
- Replacing the fire shield and procrastination with eg. 2 fog shields lowers the use of fire quanta and time quanta and improves your defenses.
- Remove 1 boneyard because indeed 1 is enough. In fact you could remove both boneyards and rain of fire, and instead concentrate on speeding up the mummy+rewind combo.
- Short sword and graboid might be a good source of damage, but they are not useful in your combo. Replacing them with eg. 2 reverse times (or an Eternity if you have one), would increase your chances of igniting the combo, while you can still use any excess reverse times on your opponent.
- The whole deck still needs a number of cards to work properly, so you might add an hourglass to help in case of a bad draw.
- The deck is still quite heavy on

, especially if you add hourglasses, so adding a few

factories might help.
The resulting deck might look like that:
4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 52t 52t 52t 52t 5c6 5c6 5og 5og 5rg 5rg 5rg 5rg 5rg 5rk 5rk 5rk 5rk 5rk 5rk 5rl 5rl 5up
Of course you don't have to make all these changes, just change anything that fits your playing style. I just hope my suggestions help you to develop your idea.
