1v1
i use prophet of regret because it is a good rusher and defender if you know how to use it well because of its energy shields and the upgrades for it. I usually just scout the enemy base with my ghost and see what the enemy is building. when my prophet is ready (i get temple>warehouse>warehouse) i get the fuel rod cannon upgrade for my prophet immediately when i can, then i go to the enemy base and destroy any buildings that are building and aim for the temple and warehouses. Later when i have more units, i'll send them. (i always keep my base locked down to make the enemy think i have no units) If they use infantry, i use wraith and jackals, if they use vehicles, i'll use hunters and banshees and if they use air, i'll use vampires and grunts(because in the new patch, grunts do signifigantly more damage to air units and they are a defence against other units the enemy might make that the vampires will be weak to. If the rush fails, i'll retreat. if the rush works, i upgrade things for my prophet only to improve rushing.
2v2
I get captain cutter because of the odst drop ability and the mac cannons. It is good in 2v2 because the enemy doesnt really have much time to build stronger units before we actually attack and that goes the same for us. So i get odst's because they are simple and useful and i can send reinforcements to allys when they need it. I dont have to worry about the enemy getting strong units because this is 2v2, not 3v3 so they dont get as much time to build up their army. plus i can talk to 1 ally better than to 2 people. I also bring along a few spartans and some elephants when i attack the enemy base so i can get reinforcement flamethrowers if they have infantry and spartans if any of the original 3 die. I use the spartans to jack the enemy's important vehicles and i kill them by surrounding their base with infantry so they dont die as easily.
3v3
I get prophet of regret because it is a very good unit for clearing an army or damaging it in 3v3. I dont build units like i normally do or rush. all i do is scout first with my ghost, then i take any reactors there are on the map and i hurry and get to tech level 3. Then i get 2 scarabs and 10 engineers. This is a very supporting army for my other 2 allys. If the enemy builds scarabs, i can use my prophets ability to damage the engineers(if they have any) that are around the scarab and damage the scarab so it is easier to kill with my scarab. i also get the engineers to heal the scarabs.
Please tell me what u think about these strats.
