I'm still on the fence about writing this. I really like Lucifer's design, but when I realized she was an OCG-exclusive collab card with no support cards that I'm aware of, I decided to try building a deck around her in an era before Synchros existed, hence why we're in the GX era.
I built this deck for casual duels with friends. I did my best to optimize it, but with thousands of cards to choose from, even limiting myself to the GX era, this was about as good as I could make it. (I set my filter to only show cards released through December 31, 2008. I know some Synchros came out in late 2008, but I'm not using those anyway, so I'll say it's fine.)
