I went for a Baron double Tactician deck, vs. my opponent who went for an engine with a ton of Laboratories for draw, and a Baron for +Buy. I get a great start with a Tactician/Lab T3 and T4, by opponents engine sets up a little faster than mine. He builds up to 1 Province and Laboratory turns. I screw up my double Tact by Forging all my hand so I can't trigger my other Tactician on T11 and lose a turn. I also Forge 2 Estates that I need for my double Baron.
At the start of my T13, I haven't bought any provinces, and my opponent already has 3. I try to just buy provinces hoping that he will stall, but I'm just to far behind to win doing that. A double Tactician with Cellar, can hold a lot more green than his deck can (cellar just loves big hand size). I decide to give up on provinces and drag out the game as long as possible while buying any gardens as I can. In the end my deck stays strong just a little bit longer and I'm able to win by 1 point. I think reacting to your opponents deck composition, is really important but is rarely talked about.
