I'm having a huge problem solving the Zedruu puzzle. That is, making a deck where she's important but the deck isn't just a lame donate duck. Mixing control with getting the engine going and eventually winning is quite a lot for that uneasy mix of colours.
I think I've found the key to the puzzle that allows Zedruu to give away crazy permanents ....... for benefit!
One obvious additional advantage to Confusion is that you don't need Bazar Trader, Donate or Zedruu to give away your nasty artifacts or enchantments, they just fly away automatically when they come into play. Other players are extremely unlikely to choose to pick up a Lich's Tomb or Illusions of Grandeur from some unfortunate victim which makes sure your gifts remain given.
