Indeed; my opponent and I discussed how much a +Actions or +Buy would have helped that engine (though the latter might have helped his Gardens deck enough to end the game before I got going).
I'm sure there is some optimization to be done (on both sides; Warehouse was mentioned post-game as the card he probably should have been gaining, over Oasis). But there was something pretty thrilling about going from a deck that's struggling just to get to $5 on turn 11, to an insane turn 12 with the addition of a single card.
