Errr, so how do you summon Ra? Read Mogu text: If your board is full of MOGU CULTISTS... So Shudder do nothing here.
The only way that I see is using Thaurissan reducing Grumble, mogu and spell stone, then using the elemental that reduces 1 for grumble. Then next turn use 1 mogu + spell stone + grumble, now you have 5 mogu in hand, then us 4 mogu + spellstone. Otherwise, how do you summon Ra??

Electra Stormsurge to double the effect of Greater Sapphire Spellstone on Mogu Cultist, then kill electra with Lightning Bolt and play second Mogu Cultist. Another option is to play Emperor Thaurissan and Drakkari Enchanter with both spellstones and both cultists in the hand.

Shudderwock is here to draw cards after playing Jepetto Joybuzz and to get the second heal Reno Jackson.

I know it's a meme kinda, and it's not supposed to be consistent but making it a Reno deck is really pushing the limits lol. I played a lot of overload spellstone shaman back in the day and let me tell you, it is HARD to upgrade those spellstones. I would still put the overload(3) cards back in the deck like Drakkari and Rain of Frogs. Also shudderwock with doppelgangster is not doing much here, its hard enough to make a reno shudder deck. Imo is good if its not a reno, but just my opinion

It's not that hard to upgrade spellstones, Storm Chaser is here to draw them. Crushing Hand and Elemental Destruction can upgrade spellstones. Shudderwock is for the heal, Doppelgangster can potentially make it infinite, although I'm thinking about replacing it with Fire Plume Harbinger.
