Alright, step one, Enchantress's Presence over Verduran.
They're in there. He has twelve enchantresses, and I would never run fewer than eleven; otherwise, the deck stalls too often.
I've been testing mono-g and G/w versions for a little while now, and have come to the conclusion that trying to go for pure speed is not an effective strategy. Almost all other combo decks will be able to race you, and it isn't terribly difficult for aggro-control to counter your combo pieces long enough to win. There are a few options I've thought of:
1. Running a U/g version, like what is being discussed in the Open Vintage thread. While this does have merits, you're probably better off playing Trix if you're going to play a blue deck with a two-card combo.
2. Playing a mono-green version with maindeck Null Rod and Root Maze. Explorations and the enchantment acceleration put you at an advantage under Root Maze, so you'll have a better chance against combo and possibly Control Slaver.
3. One could play a G/w control version of this, seeking to play an enchantress effect and a Solitary Confinement to hold out until the combo can be found. I personally doubt this can work, since it is somewhat slow and quite risky, but it might be worth a try.
4. Somewhat a combination of #2 and #3: starting with a decklist similar to what JP posted earlier, but with some combination of Solitary Confinement, Root Maze, Null Rod, Ground Seal, Seal of Cleansing, Oxidize, and Engineered Explosives (for Chalices) between the maindeck and the sideboard. This is what I've had the most success with so far, but I'm having trouble finding room for everything I need - enchantments are just too damn narrow

As far as SuperGro, as stated earlier, Psychatog is just too much better for it to work. Unless a version that has a better game against workshops than Tog can be built, there's no reason to play it.
The problem with Parfait is that it just sits on its ass while opponents do broken stuff. It still has the same problem that has plagued enchantment-based decks since their invention - they are control decks that lack Force of Will. That being said, it -does- have a respectable chance of winning against anything non-combo. Because it will almost surely lose to any form of combo, however, the chances of it making top8 at a competitive tournament are rather slim.
