I keep seeing Scarab Mummy decks and the marks are always Gravity, which allows you to maintain at maximum one Scarab a turn. Wouldn't it be better to have a Death mark, which would allow you to play only one Mummy every four turns, but since you're going to Rewind it anyway, you don't really need the Death. In addition, you could always Fractal the Pharoahs, which (I'm assuming) would give you a hand full of Pharoahs.
The other thing is Fractal/Hope decks. Yes, you could simply RoL, but that's boring. I was thinking Death/Light (Condor/White Nymph/Boneyard) would be viable now, with some form of creature generation and destruction (Fractal + Spark/Alfatoxin with Thunderstorm/Unstable Gas)
