The big carry-home from this article is my rubric for playing Brainstorm over Ponder and vice versa and for playing Duress over Thoughtseize and vice versa.
Nice article Steve. After reading that though, I don't think the big carry-home is when to play Brainstorm or Ponder, or Duress or Thoughtseize. To me, at least, all of that should be obvious.
I think the most interesting part of the article was how you wrote about your note taking distracting you from the situation at hand in games, and thus forcing you to go to time more often. This is a problem I've noticed you had in the past, and noticed when I played against you last (I want to say during the Vintage Championship in like round 6 or something, but I can't remember exactly). When we played, you were scribbling notes frantically, while I was focused entirely on your actions, and a few times called out if a spell would be resolving or not before you even cast it (I'm not sure if you remember). I knew all the lines of play for you because of my focus on the match.
Notating storm count and knowledge of opponent's hand is important, as is how life is lost for each player (as this may need to be retraced later if a disput arises). Simply notating life total like this is enough:
20 19 PD ----> for Polluted Delta
15 QD ----> for Quirion Dryad
Other than keeping track of those 3 things, all of your energy should be focused on analyzing the opponent and lines of play. I see it worked out great for you in this tournament, and I think you'll be an even stronger player going forward because of it. I'm looking forward to a rematch.
