You want to open Baker/Chapel regardless of your strategy. I don't like opening Adventurer, but the best way to counter it is to first get a really trim deck and only then go for Familiars, so that you give your opponent all Curses in 4 turns (ideally 2-3-3-2, i.e. I wouldn't play the first Familiar if I don't have to). Merchant Ship doesn't fit in with this strategy, and if you go for an early Potion, as KingZog did, you should get Alchemists until you're at the point where you draw your deck each turn.
