i go 3 gate blink stalker every single game in team games basically.
you are able to hold most early rushes (cept 2 people ling rushing you perhaps, but still holdable)
you can help your teammates and beat lower tech armies with blink easily. very well-rounded early army of 1 unit :P.
get a forge too at some point once you have like 6-10 stalkers, and place a cannon in your minerals so you dont die to dts/other silly things. this isnt 100% needed, but it might save you :)..
transition into expansion with coloss + more stalkers OR storm + many zealots + your existing stalkers... recommend storm vs >1 terran on enemy team, and coloss vs everything else.
3 blink stalker:
gateway (13~ supply first gas) -> cyber (second gas right after) -> citadel -> drop 2 more gates @ 50% warp gate research/get blink.
IT IS IMPORTANT THAT YOU HAVE 16-17 WORKERS ON MINERALS by the time you are producing off the 3 gates. and then 6 more for both your gasses. take your second gas after you drop your cyber core.
TOTAL 22 or 23 workers!!!
keep producing stalkers on 1 base if you think you can win/harass someone to death. else you cut stalkers and take your expo.
this is basically a guide on how to get masters easily in any teamgame setup. obviously add earlier units if you scout extreme aggression...like zealots to block your wall and sentries to hold silly all in early rushes.
you may thank me by don8 :). I have been R1 in 3v3 and 2v2 (maybe r3 or something), and this is what i do the majority of games out of necessity. other option is robo, but you are half as mobile.
