While I can appreciate what you're going for, it feels like too much is going on. For example, the Devourers and Sparks contradict each other. In the long run, just four Devourers and four Sparks are useless (they don't do enough). In order for either of these to be effective, you need to fractal them; but due to quantum production, you'll probably have to pick one. Do you want to kill them with sparks, or drain them with Devourers? You can't do both at once. Further, if you intend to just Immolate a Spark, then you have to wait until you have both cards in your hand, since the Spark only survives for the turn it was played--individually they are just dead weight. Even if you Immolate all four sparks, you've only gained 28 fire quanta, so your fire bolts will only do 9 damage, maybe 12 or 15 if your QTs have made some extra fire, but you're certainly not going to kill someone off. If you Immolate Devourers, you're gaining fire quanta at the cost of your draining strategy.
You're being 50% effective in three different deck strategies. I'd try to focus more by using a speed deck: Fire (Fire Bolt them to death), Darkness (Devs drain their quantum, Vamps drain their life/heal you), Aether (Dim Shields to stall, Lobo for creature control, Twin Universe and Fractal to make an army).
