Old but Gold protoss

As everyone mentioned Skytoss is expensive, the real way to deal with it other then going skytoss is hitting enemy before he gets the golden Armada. And even if he gets it you dont loose your chance because other than phoneix skytoss is too immobile, you can make him split his armada by dropping some zealots even archons to extensions, and worst case scenario you can go for base trade while proxying some pylons across the map that way you can outrun golden armada and finish your enemy. PS:: Archons not that useful except massvoidrays because their low movement speed, they will evaporate before reaching tempest and carriers
