I tested this kingdom a few times earlier today and this is what I learned:
game 1: Basically that this can be very fast. My opponent does not play very well, with some weird sort of masq-BM, with a late potion. Regardless, I was one coin away from being able to have the buying power for 8 provinces in 13 turns. I opened celler/potion, getting apothecary/market square t3/t4. From there it just rolled, picking up a second potion and having 8 apothecaries by the end of t9.
game 2: A much better opponent. I was forced into the celler/potion here because of a 5/2, and Breezy went masq/potion. I got my second potion before a market square here, which i think is a mistake. We end up even on the apothecary split, but I am starting to run into some trouble when, after 10 turns I have 3 potions, necro, and OE due to his masq passing. So I purchase a double urchin t11 which I am able to start playing on t13. I think Breezy would have won this one had he just gone coppersmith, but he got distracted by the market square when-you-trash-from-your-hand benefit, gained some golds, and really slowed down his deck and prevented his apothecaries to be really useful. I end up with 5 provinces in 16 turns, which is enough to win.
game 3: accidentally played this one with 3 estates, which makes a huge difference because of the lack of villages. I again open celler/potion to his masq/potion. I get my market square before my second potion, and a little due to his bad luck getting EEECP t3 I am able to win the apothecary split 7-3. He is also unable to utilize his masquerade as well, and I am able to get 4 provinces by t12 and slog it out for 6 provinces after 16. One variance I added here was utilizing begger to gain coppers.
Overall thoughts: I would like to play this game opening masq/potion just to see how different it is, but I really like my celler/potion. celler provides better (or just as good) cycling as masquerade, it is not a terminal (important), and is much more useful late game. I really liked how I was able to clean up a bit mid-game in my second game purchasing urchin-urchin then quickly utilizing the mercenary. Overall, the uncontested engine is a clear win, and I think that apothecary/celler/market square/coppersmith is the backbone of a winning strategy (with a crossroads for actions).
