Suggested upping order?
Dials are a must, obviously. Next I'd say poison and then SoSac. Both of them are crucial i.e. the deck won't really work with them unupped. Then it would be Bone Towers, which also helps a lot. Last is Arsenics and SoDs.
Obtain these before attempting to use the deck:
6 Sundial
6 Poison
3 SoSac
Then, upgrading the following helps a lot:
5 Bone Tower
3 SoSac
2 Bone Tower
Now your deck is good to go. Upgrade the following to complete the deck:
2 SoD
2 Arsenic
1 SoD
