Help with installing mods that don't have core files?

I've been trying to download and install The Firemind's Scion of Darkness's, and East Bay's decks, among others, but even when I attempt to move all of the separate content into the correct folders in the "Custom" folder created with Riiak's Deckbuilder, the decks do not appear in-game and appear incomplete (missing artwork or cards) when I view them in the Deckbuilder. So far I have been able to install all of the mods with core wad files without encountering any problems, but haven't had any luck with any of the individual mods except Balmung. Can anyone give me some advice on how to get the decks with downloads split across multiple files working properly, or be kind enough to upload some of them as single core wads so that I can get them working myself? Any help you could offer me would be greatly appreciated, as I've tried downloading and installing the Firemind's, Scion of Darkness's, and East Bay's files and decks multiple times without any success.
Thanks for all your help.
