Tbh I dont think there are really any different builds at SEA top level than anywhere else in the world (or at least, not greatly different). What does go on is mind games because every top player hits every other top player in every tournament. There arent "secret" builds - just every day builds have been given new names dependint on who popularised them within our region. Targa banes = bane bust. Jerry build = hidden mass ling.
To find replays you can look on this website's uploaded replays, however you won't find much in the way of zvz at the tip top level as mafia mentioned since players dont want to reveal their styles to each other in case they need to face off in a tournament at some point. Youre just as well off looking at games from any other pro players which have more accessible replays.
