Yeah, I would take out the fire shields. You're either going to win really fast with this deck, and you won't need them, or else you'll fizzle and run out of steam, and it won't matter whether you have it or not. I'd also consider using vampire stiletto instead of fahrenheit. You can cast it off immolation, and given your low fire quanta production, a fahrenheit is unlikely to ever do more than 5 or 6 damage, anyway.
I don't know if you ever plan to upgrade the deck, but RoLs instead of photons and maybe two seraphs squeezed in there (in place of fire bolts perhaps?) could possibly work, though as Gandora mentioned, Lava Golem is also a great suggestion, and probably better than seraph. You could look at adding one or two other cheap splash cards cast off of the immolation, like nightmare or fog shield or lightning or things like that, but in the unupped environment there are very few good ones you can cast for just 1 quanta, so I probably wouldn't bother other than the vampire stiletto I mentioned.
