Abilties i would suggest you take out are:
arcane missilies, everlasting cold, counterspell, mana agate, brittilize,polymorph, spell ricochet, blink, cold front,smoke or croak, frostbolt, fire and ice, and pyroblast.
You should use abilities like nether fracture, fizzle, metalmorph (i see you have 1 in there but you will want more than 1),blast wave (again multiples of that card), dragon's breath, invocation, and possibly touch of ice and brain lock if you want to lock them out of card draw even though you are fire.
When deckbuilding it is pretty key to try not to use only 1 copy of a card. Sometimes is may randomly fit only using 1 but it is important to run copies of the good cards so they appear more often when you need them.
