It's too bad that Time Spiral with its awesome throwback reprints was so long ago. I never see Pandemonium anymore. It is probably my favorite red enchantment of all time, and generally one of the coolest enchantments out there. At four mana and with a rather volatile effect, it is unfortunately lacking in a home as a tournament card. It is not Legacy playable and doesn't have a niche in Modern either. Then again, those formats have huge card pools and tend to see focus on breaking the game. Pandemonium was viable during its tenures in Extended (once from Exodus and once from Time Spiral). So for a casual player who likes fun cards, but doesn't want the most broken stuff, maybe Pandemonium is a great fit. I can think of a lot of uses for it. My earliest attempts involved Phyrexian Dreadnought, but power-level errata invalidated that deck, something that was eventually reversed.
