Lots of times probably, but when your deck has 8 Ventures and 2 Coppers has got to be up there. Much better to have the Copper in your hand. Too bad I didn't realize the advantage at the time.
A lot of really interesting interactions in this game, which I don't pretend I played as well as I might have:
http://dominion.isotropic.org/gamelog/201303/10/game-20130310-203331-019d611b.htmlProbably should have picked Minion or Venture rather than trying to combine the strategies -- Minions like Minion density more than anything. But when I saw the opportunity to Mint away my Copper, buy some Ventures, and then Mint more Ventures, I couldn't resist. Should I have Minted the last two Coppers away too? And then I foolishly didn't fight for the Nobles because I thought I would grab the Provinces fast enough to make them moot, which obviously didn't happen.
On the other hand, there's nothing more satisfying than playing a Venture and knowing it will find all the treasure in your deck.
