The strategy is actually pretty similar for a lot of the FGs.
- Get a Quint'd Otyugh and Quint'd Druid in play as fast as possible for creature control.
- If you can wait, play the Boneyard and Bone Wall before Rain of Fire, to give both a nice boost.
- Use the Dimensional Shield and Sundials to stall until you're set up.
- Use Eternity to prevent from decking out.
I always found I was stuck with a handful of Sundials and Hourglasses, so I took out one of each and put in a Miracle and 3rd Quintessence for the FFQ, and it helps a lot. It takes time to set up, so the big threats are any gods that can put out lots of big creatures quickly (Divine Glory, Eternal Phoenix, Osiris, anyone who tends to use Fractal) or who can cut off your quanta supply (Dark Matter, Decay, Seism). Once the lock is in, this deck is hard to beat; I've actually decked out Rainbow using it. The deck is focused on surviving long enough to get a very specific combo out, so if you keep that in mind, the strategy will come to you.
Useful cards:
- Thorn Carapace or Fire Shield, against Divine Glory
- Purify, against Scorpio and Morte
- Reflecting or Jade Shield, against Octane
- Dissipation Field (upped), against anyone. In the late game when you have quanta to spare, I think this may even be better than Bone Wall.
Chaos Lord, Destiny, Elidnis, Ferox, Fire Queen, Incarnate, Miracle, Neptune and Paradox are all pretty simple, as long as you don't get a spectacularly bad draw.
