I ve been using this deck for the last week.
I ve gotta say it works pretty great; obviously sometimes you just get a bad drawing fist 3 hands and there is nothing you can do about it. But apart from that, very consistent deck.
On the upgrade subject:
I had 3 elite oughtys from my first gravity deck (yeah, i started having a semi-fast build-up gravity deck, with mark of fire; 3 elite oughtys, 4 firegravitons, 2 sphire chargers, etc.
If i had to upgrade from zero this deck i would do:
1. Oughtys (at least get 2 upgraded):
I can't count the times they have saved my ass eating my enemy's creature
2. Hourglass.
The time quanta needed is huge; plus you get to draw a lot of cards, so i would recommend (in contradiction with SG) to get a 40~50 card deck. Sometimes you just don't get good cards.
Maybe when you have no upgraded card, you wan to add 1 time pillar (or 2).
Each eternity costs 6, and 3 the magic (always talking about unuped weaps)
Hourglass costs 4, and 2 the magic
sundial costs 1
You will have the feeling you are always running short on time quanta.
3. Fallen Druid
Makes a huge diferrence in long games, when you get to build up your army of only elite monsters
4. Buy novas (or if you have previuos) upgrade them to supernovas.
For each supernova you add, takeout a pillar.
5. Start adding some more shields.
I ve found very useful:
1 (more) phase shield
1 fire buckler
1 procrastination
6. If you got any good weapons, add them:
the most useful on this deck IMHO
owls eye (help getting skeletons)
pulverizer (helps against poison/shielding/destroyer enemys)
also remember to add some flying weapons. (1 for every 2 weapons of the same type)
7. If you get any miracle or improved miracle put it in.
When you get FFQ on the table, you wil start having a lot of light quanta, plus helps a lot getting the element mastery. If you upgrade to Elite.FFQ, maybe not such a good idea.
8. After this, upgrades could go on anything, maybe upgrade weapons, towers, shields. (in any given order)
