This the old, Heart of the Swarm, zealot + immortal with warp prism, all-in from Naniwa. I made a few changes to adapt it the LotV changes and works for me perfectly. A lot of master players don't manage to defend even when they scout it so it's good for higher leagues too. You don't need perfect micro to make it work and it's easy to learn.
The second warp prism is to fight easier. One warp prism for microing damaged immortals and one for warping in units or when the first one is killed. After the first wave of warped zealots, if there are no zerglings/roaches, warp stalkers as most probably mutas are on the way.
