4. Ptolemaic Camel Archer Rush.
Instead of building a barracks after the 2nd house, you build a stable and start making Camel Archers. In a 4v4 teamgame, your pocket can even send you a bit of food to get even more camels out even faster. With good micro, you will not lose many of your camels, especially if your enemy didnt expect that rush. Then after you annoyed your opponent for 5min, you could add your own barracks at some point and go back to eco-ing while still using your one stable to keep up some pressure on some women somewhere (maybe the enemy pocket or the other flank?).
But I like to double down on my rush instead, by adding a second stable and using the cc as a stable aswell. Once you have like, 30-40 camels its gonna be hard for your enemy to do anything, as he doesnt have the stables to make enough counter cavalry.
If the game goes on to 2nd phase or further, remember: If you let your camels take damage, you already mis-played... so you don't need any armor upgrades. Only ranged damage.
[I like this strategy as I wish to believe I invented it (most likely someone did it before me, but I didnt know about that, so I came up with it myself, okay?!)]
