I probably beat the Warriors 10-15 times (or more?) with the 76ers last year in PNO games. Sometimes the users even knew what they were doing!
Definitely have to be active on defense. Have to stay on your toes on that end, for sure, and be prepared for an early onslaught of pace + 3 point shooting.
On offense you just have to take good shots. Don't rush anything and wait for the defense to make a mistake. Trust me, they will, and when they do you take advantage of that.
