I don't have three Fahrenheits, but I tried this deck in the trainr and it worked like a dream. Of course, perm destruction is an auto-lose. However, earthquakes don't necessarily kill this deck, depending on how many your opponent packs.
The strategy I used was to wait until my opponent can't quite kill my in two turns, then start chaining dim shields. This will at least give me a chance if he pulls momentumed creatures/perm destruction.
With all that fire quanta piled up, Fahrenheit finishes the game in 6-8 turns.
I can't think of anything I'd change, but then again I can't test it against in-game AI5s (I hear they play differently in the trainer).
Against gods with explosions/pulvy, you can try adding 4-5 enchant artifacts and a couple aether pillars and changing your mark to earth.
Thanks for posting, keep up the great work!
