Notes & Combos
Going first: Summon blocker + protection. Golgonda is great against Vanquish Soul. Still, Vanquish Soul is quite tough.
Going second: Summon blocker + Moon Mirror Shield / Nadir Servant / Herald / Raigeki.

Thanks for this list! I kept getting to D1 and then deranking with other decks. Decided to try this with a few small tweaks and finally made it.

Here's what I ended up with: https://www.masterduelmeta.com/saved-decks/6565eef1c7ad3b2f56f566f2
Morganite was really useful in the grind game, love to see it in an opening hand. The tweaks the ED were mostly because I didn't want to craft new URs. I never was able to use Granguinol's effect to summon Despian Proskenion, but I thought that possibility was fun. Mereologic came up in a couple of games, but it's effect is slow so I don't love it.
