Okay, this is a better strategy against newbies. But anyways, once you begin as toss, build your pylons, gateways, cybernetics cores, ect. Then send a single zealot out. this is your "kamikazi" zealot. dont give it orders to fight, just walk as far as possible into enemy territory. this zealot wont live long, but his purpose was well served. (dont use a probe to explore. you may be tempted to, but zealots shields and toughness are what made me choose them.) then send a probe directly above his base, and another directly below. then build gateways and start pumping out dragoons. then send a group of say 19-24 zealots from your base into his to draw attention. then send in the dragoons. it is best if you have 2 groups of 12 on each side. this requires crushing amouts of minerals, so have say 20 probes working on it. this will overwhelm your opponent, and before you know it, all d is gone. then you move in, and we all know where it goes from there.

CreepColony's Opinion: This is a pretty cheap strategy, but may or may not work depending on what your opponent has.
