going lategame is fine, you just need a mothership and a good amount of voidrays, and eventually archons too. If you want to macro, find a build that gets you a fast third base.
immortal timings are strong, FFE into: 3 immortals + warp prism + 8 gates + lots of sentries. aim to hit at 10-11 minute mark. Don't have a precise build order myself, but that's what you should aim for.
