Alternatively, if you want the Fire to fuel Death (quite fun!) try removing your Aflatoxins, Plague, Skull Shields, all of your Fire creatures, 3 Fire Pillars, make your Mark Fire, maybe remove 2 Bone Pillars, take out 1 Boneyard and switch with a Vulture, add a Fire Shield and a few other duplicate Fire spells until you reach 30 or 32 cards. That will probably provide you with the most flexible Fire/Death combo relying on creature destruction.
