I can't be of much help to refining the build, but I wanted to share my experience so far. My friend and I do a gauntlet of the best PT decks all week before each game day, and this is the deck she'll likely be playing due to card availability.
In our testing, Pierre's list is great at not losing, but has a lot of trouble with actually winning. When you draw the right cards (a couple towers, a couple counterspells, plus any removal needed) this deck is very good. If you draw the wrong half of your deck, you spin tires for 10 or 12 turns and lose. When that happens, it feels like a ramp deck that can't stop drawing ramp spells and lands. That's been our testing and we're not sure where to go with it. Seems to have a particularly poor matchup against aetherworks due to basically being counterspell or bust, and not being able to burn them out before they just clobber you. We really like the deck and she'll probably be stuck playing it, at least for this weekend, so if anybody finds any improvements let us know.
Also, I definitely have no problem acknowledging that he didn't go 8-2 at the PT by mistake, and the deck is at least decent. It still feels really lethargic and inconsistent to us though.
