Lots of laddering. On occasion someone like pig, light, jimdiddy or whoever asks for some practice matches. Those are good, but not part of my usual "how does I get this build and transitions to work"
While you have a great mindset of practicing transitions, I feel you are under utilizing practice partners, ladder will never be as effective as correct practice with teammates/friends.
For example, you want to know build A vs reaction A,B,C,D,E so you practice 5 games, then you want to do the transition out of A. so then you have, A vs, A1,A2,A3 ALL of the different possibilities. You can grind this out in a day. This is how it is done because its the most effective, sure it sounds boring etc, but that's how when you see Koreans make instant decisions, its because they don't have to think they already have played every possible situations and practiced what the best response is.
Try the practice partner way and i guarantee your game will be boosted 100x higher. Even if you don't have a team to do it practice partners can be effective for this as well.
