i would say to take out both the fire bolts. because your never going to generate enough quanta for them to work well. i would say to get rid of the fire bolts in favor of 2 fire shields.
they are utility spells, they are great CC, and you do have enough quanta for them to be effective, since they are mainly used for CC, after an immolation, u r likely to have more than 10 quanta, and that's 6 damage plenty to take out most creatures, and you will still have about 10 or so (which means you can play a dragon or phoenix next turn) quanta the turn after.
fire shields are great and all, but they are slow CC, and in PvP1 people generally use rush decks, and a lot of them also use a lot of growing creatures (the grow out-heals the dmg from fire shield).
fire shields also cost 6 quanta, that's a lot, considering this is a semi-rush
