I was thinking of veilstone amulet to protect the combo from everything but counters as its a global effect and only requires a cast not a resolve.

As far as I can tell there's no kill mechanism there yet is there? I think cunning wish is standard, and stroke of genius + braingeyser in the sideboard. I don't have much experience but 3 cunning wishes seems decent.

Spell pierce seems more versatile than disrupt. It can catch artifacts and the occasional rogue enchantment, and is harder for someone to get around by paying the mana. Have you tested it?

How about lotus petal? Since you don't have any moxen/lotus available it should be good helpful.

That leaves 3 slots. If you're getting crushed by wastelands and/or blood moon a basic swamp would be good.  If you do add a basic swamp, switch the scalding tarns for fetchlands that can find swamps of course. If you have trouble with leyline or other graveyard disruption, another chain of vapor or echoing truth would be good. If you have trouble with key spells getting countered, spell pierces are useful.

I would put another chain of vapor in the sideboard to wish for. If you're running into people with power, null rods would be good too.

a lot of dragon decks used either stroke of genius, caller of the claw, Oona Queen of the Fae or even bitter ordeal as a win con for a dragon deck. you are missing a win con for sure

also can probably add

Misdirection
Frantic Search
Demonic Consultation
Darkblast

maybe add in Tormond's Crypt or Relic of Prog in the main deck too *for dredge*

I just may add to this respect that in case of adding any graveyard hate I'd add Tormod's to prevent any weird but possible drawback from Relic.

you should play a fourth WGD main deck and 1 living wish sideboard. that way you see the dragon with study or thoughtseize more often and, you can board out 1 dragon for 1 wish for extirpate defense.
as far as maindeck hate like crypt/relic, i wouldn't recomend it. however if it is a course you deem to be beneficial, i would suggest something with flashback to increase intuition synergy. ancient grudge, ray of revelation, or coffin purge.
also being unpowered you have sufficient room for an altermate win con. i would focus on that in the decks construction. maybe Iona and a reanimate spell. or better yet something eay to set up with tutors that doesn't abuse the yard.
