Howdy yall, this would be my first post ever on Paizo
Welcome aboard!
I do not know is who the god actually is. The DM of my game has what he wants it to be, but refuses to tell me.
That's a house-rule then; Oracles get their spells from several sources and not from a single Deity.
My character's end goal will probably to destroy the god, after amassing a good following, and then ascending to godhood him/herself.
That's going to be tricky: when your powers come from that single God, you'd be a high level Commoner the moment it dies.
I don't think you're going to have good enough stats to play an oracle who does both offensive spellcasting and melee. As such eldritch heritage (draconic) isn't going to be good for you - the claws aren't great and the later powers aren't better than the spells you can get as an oracle. If you must have some dragon flavour then traits like blood of dragons, or draconic infusion would be better for you IMO. A better feat would be noble scion (scion of war), or combat casting, or burning amplification.
Assuming demand is a typo for command all 4 of your 1st level spells are attack spells. That's a bit much. You want at least one spell for defence (sanctuary, obscuring mist, shield of faith, or maybe protection from evil) unless you're suicidal. Maybe drop doom? On your 0-level spells, bleed is useless - replace it with anything else.
The misfortune revelation is the highlight of the dual-cursed archetype and I'd get it at level 1.
Bleed is inferior to a thrown dagger, which isn't going to miss a helpless target often. Still, if your GM says you might need it, you might I guess. Just keep a dagger handy too.
Do you have to have the Eldritch Heritage (draconic)? If you have attributes like Str 13, Dex 13, Con 13, Int 12, Wis 9, Cha 17 (which is about as martial as those rolls allow an elf oracle who wants to cast offensive spells) then you're still going to be pretty hopeless in melee with the claws.
Wildblooded isn't technically available via eldritch heritage, it's an archetype. Besides that Linnorm still isn't that good being fairly low damage. Just 1d6 when you could get it at level 3 as your sorcerer level is character level -2; enough to take out a kobold warrior in one hit 1/6 of the time, and to disable it another 1/6. Not good odds.
Most of the attacks of the 1st level bloodline powers are forgettable. If possible you'd want to search out one of the few non-attack effects or to accept the feats as a cost of getting a good Improved Eldritch Heritage at level 11.
As an example of the first, Destined or Martyred give minor buffs. For the second, Shadow gives a nice stealth ability as a level 9 bloodline power.
