I'm making a survival build for guardian druid for dungeons, lfr and a bit of battleground. I have Soul of the Archdruid and Dual Determination. Now I got Cinidaria, the Symbiote. Should I choose it over my existing two?

hello, so i am following this deck - https://www.icy-veins.com/hearthstone/elemental-mage-deck and i was wondering which card i should buy next and i dont have much dust left. I need the following cards
Primordial Glyph x2
Pyros x1
Arcane Keysmith x2
Blazecaller x2
Frost Lich Jaina x1
 
I have 1945 dust left with the option to disenchant "Archmage Arugal" with a total of 2345, because i dont use it, nor do i know if its any good?
 
 
I can either go with x2 Primordial as the guide says this is needed for the deck + x2 Blazecaller for late and x1 Arcane Keysmith? but then  i wont have the pyros for early or Jaina for late.
 
Or i can go balls out buying x1 Frost lich jaina and x1 primordial glyph ? / Or just Pyros and x1 Primordial. I dont know.
 
My last scenario is buying Frost lich jaina and x1 primordial by selling some rare cards, then use "Archmage Arugal" instead of Pyros for the time being and combo it up with AI for 2 extra cards, and hope its something good.
 
 
 
any help is grately appreciated.

Hello! 
I'm pretty good with weak auras and even some lua code but i cannot for the life of me figure out how to make this weak aura.
heres the basic function i want:
Prototype Personal Decimator - only fires a missile when you are at least 10 yards away.
I want the icon to show when I am <10 yards ( too close) to my target to remind me to back up. Once i am >=10 yards, i want the icon to hide.
it sounds simple but i cant figure it out
can anyone help me figure this out please ? :)

As a retribution Pally should I equip the Insignia of the Grand Army instead of either Soul of the Highlord or Chain of Thrayn.  Could not find in the icy-veins guide about this ring.
Thanks
 

I have enough dust to finally craft a legendary card but no idea  which card to craft. My deck has dk anduin in it. It isn't a top tier deck. This is my deck list> ###
