That's very goo MrFool. You might not know all of ZvP yet but you still have all the knowledge that is extremely good.
I haven't seen the replay but I'm surprised player didn't make roach. They are very standard in ZvP. Cheap, easy to use and very efficient. Hydras are very good vs Stalkers and Immortals combo since they both target armored units and Hydras are light. When you begin to have templar, Archons, you need T3, Broodlords or Ultralisks.
