Here's a game I just won:
http://dominion.isotropic.org/gamelog/201202/13/game-20120213-125122-f90084ba.htmlScrying Pool makes me very nervous, as I don't consider myself very good with 'em. But my opponent opened Pirate Ship, and I figured that with him trashing some of my Coppers, Scrying Pool would be really strong here--plus there were good Actions to load up on, Native Village, Stables, Oracle, Smithy, and Cutpurse. No extra buy, though.
I got decently lucky in that most of his initial Pirate Ships miss entirely--of course, I was loading up on Actions, so I'm not sure that was unexpected. Anyway, everything goes according to plan, he knocks me down to just 3 Coppers, my Scrying Pools go great, I keep him under attack with Oracle and Cutpurse, and I score an easy win.
My question is this: If he hadn't opened Pirate Ship, should I have still bought Scrying Pool? Or done something fairly conventional with Stables, or Smithy/Big Money, or Oracle/Big Money?
