I think the most fun version of Pale Moon is the Nightmare Doll loop. All I know is that it's deadly if it gets off, but very fragile and can easily be bested by rush decks if you can't get to the combo fast enough. I only recently heard about it, so someone else should probably help you out with that and getting out a list. Thanks to the new Songstress from V-BT04, there is a loop that utilizes her that is making the rounds in tournaments. This is a decklist from a person who topped with it, which you can find on CanYouSayG's blog: It takes advantage of the magia keyword from premium, as well as the multi-attack capabilities of the Nightmare Dolls, revitalized thanks to the rebooted Alice, to create a multiple attack nightmare for your opponent. The Harri/Nightmare Doll multi-attack deck. Right now, I would say there are two builds that are competitive and topping tournaments: It still is kinda fun in premium and does top here and there.

Well, welcome back and interesting that you want to play Pale Moon in premium.
