Nemleria is definetely my favorite deck to come out in a while. The main idea with this build is that since you don't use your Extra Deck, you can still get value from it using Nadir Servant and Dogmatika Punishment. There aren't a lot of cards that get value off of it in this deck so you can max everything and just run the 5 cards. Dora is here because it's better for the deck's playstyle, but Gustav is fine too. Dragon Master Knight for pretty much exactly Chaos Angel, but it also lets Punishment out a lot of random stuff. The ratios might look wonky, but the Nemleria stuff is super easy to search, so its fine to have 2 of most of it.
*In all honesty I made the deck for TCG/OCG format, so imagine the Extravs as Prosperities and Bishbaalkin as Garura. I had to build it for OCG format to get Repette, which meant I had to sub some stuff.
