-2 Fahrenheit (you won't collect much fire quanta to make it useful, also it'ld be your only PC-target)
-3 RoF (Fractix is about speed, if your opponent can cast enough creatures so RoF would be good, you've already a big problem)
+2 Deflags (shields will hurt you a lot, believe me; just think about Fire, Skull, Phase or Diamond)
+2 Fire Pends for quanta
+1 Minor Phoenix
Probably you may remove one Fractal for another Fire pend. Well, I've already seen a long discussion in Pestal to use one more or less of it, so test it and edit in your favour.
