I don't really think either is good, but especially not the Adventurer. You MIGHT pick up a Scout, because the re-ordering could help Mystics. I think you want a lot of Mystics, and you want to gain them from Universities. I would open Potion/Warehouse, pick up a Spice Merchant ASAP, and aim to eventually play multi-Possessions.
This isn't the greatest plan, if only because your draw is limited, but you can trash well enough so I'd still say it's got to be better than just kinda playing a BM-ish deck... especially because I suppose you can make Thief relevant if your opponent tries to do that.
