If I sum up correctly, you just want to:
- play scarabs because you like them
- have EM because it's electrum-friendly
My suggestions then:
- come back to the origin deck, no novas, more towers, 6x sundials.
- add maybe 4/5 aether pendulums (remove some towers), it will help with time to add hourglasses to the deck.
- add 3 hourglass, you really need to have them upgraded
- just play 1 pharaoh maximum (even 0), you have no reason to play him in fact (no quints, no shards of readiness, etc).
- just play 3/4 scarabs
- focus on the fractal/scarab combo (it will also increase the importance of the bonds) - I think 4/5 fractal is ok
- play less buffs, your scarabs should be big enough with just their brothers on the field (should give you rooms). Just 1 or 2 upped plate armor should be enough.
- don't play the druidic staff, the bonds should be enough to heal you for the EM (if you really want a weapon, play a pulveriser for PC or an upped vampiric for healing power).
If you ever choose to follow my path, tell me how it goes.
