As a person who really enjoys the Abyss Actor archetype and loves the design of it all, I really wanted to make a fun and casual Abyss Actor deck just so I can have one. I tried to mainly go with pure Abyss Actor / Abyss Script in the main deck except for Pendulum treasure to have as a way to immediately help get the engine of the deck going and let the extra deck be the one to have a lot of good cards that can work together, such as the Nightmare archetype which I also thought looked cool and could work well together if you managed to get that many Abyss Actors out on the field to Link summon.
Along with that, in the side deck I added other Abyss Actor cards that I would think are better cards to add to the deck if there are some cards in the main deck you don't like or just want to add them and have a bigger main deck. I also didn't bother to add cards like Ash or Nibiru since this is a casual deck that I wanted to make budget friendly and if you want to add those more expensive cards, you can. But I don't think I needed to tell you that.
Overall, I really just wanted to make a base for myself as I enjoy this deck and had a lot of fun when testing this out. This may have potential as a rogue deck to cath your opponent off guard that you're crazy enough to play Abyss Actors competitively, but who knows maybe this archetype wins regionals and we're all laughing about it because that would be awesome (although I severly doubt it but I will stay a believer). But, do what you want with this deck, I just want to see people enjoy this archetype!
