Nemleria

Like Snake-Eyes, one of the main appeals of this archetype is that it uses a small core engine, so you can cram a bunch of hand traps and board breakers in to fill out the gaps.

Lava Golem and Small World go together. You can bridge it to Dreaming Nemleria using Ash Blossom, or turn an Ash Blossom into most of the Level 10 beasts by bridging on the 2500 DEF. Fenrir and Unicorn are mostly to bait out handtraps and offering a first layer of interaction on your opponent's turn. Eater of Millions is at 1 because I only have the one copy. It can let you use Dreaming Nemleria's effect very early, but be careful because you might want the ED fuel for cards like Repeter or Dream Tower.

The Extra Deck could be almost anything, the only main one you would want is Linkuriboh, or another Link-1 that you can use to get Dreaming Nemleria back on top of the Extra Deck after using its effect. Theoretically you can make Baronne de Fleur using one of the Kashtira monsters plus Ash Blossom, and then Psychic End Punisher is an option using one of Dream Defenders and Effect Veiler. From there just pick a Rank 10 toolbox, although Gustav Max and Liebe are good options for closing out games.
