Looking at your proposed set, what I see is a mixture of different damage types and debuffs, with a lot of fancy names. I'll ask the same question I've posed in various other such threads - what, specifically, makes this set "magic"? If it's the animations, then those could be added to or expanded upon for every powerset. If, ultimately, what you're after, is a set that deals a bunch of different damage types along with a smorgasbord of secondary effects, then propose that. To shoehorn in a specific origin is just counterproductive...
