I loved playing the pure version listed here for a long time. But now it seems like you really need the aleister/silent magician combo or just aleister version of it. There is too much graveyard disruption and banishing to try relying on quintet magician too much so I'm switching to the other build.
I would go with Grass is Greener, but I can't exactly risk milling all my copies of Magicalized Fusion. That, and I'd need a bunch of other Spellcasters for filler.
As for Peten, I'd need something to replace him with. Thanks to being able to discard him to CMG and Tricky, plus being able to mill him with Lyla and Merchant, he works pretty well as a temp-wall and a deck-thinner.
