Mark of Gravity
10x time tower
10x bone pillar
6x reverse time
(note- you can also add an eternity if you want)
Simple. Get your pillars out and then get a mummy out. Use reverse time on it to turn it into a pharoah. Keep doing that and use pharoah's ability to get scarabs out and eat your enemy's monsters. Just keep doing that on level 3's until you have enough money for a better deck.
