This one is for teamgames, the problem is you can only use it in 3v3 but its really strong - the immortal elephant!
You need teuton, persian and byz.
The strat is a bit of a copy of the immortal ultra seen in SC2 a few years back: One heavily upgraded unit with lots of healing behind.
Persian ofc makes elephants. You dont even need that many. They wont die. Thanks to teuton, they cant be converted that easily either. So you need about 10-20 elephants, and you spam some hussars to kill enemy monks.
The teuton players has monks with double healing rate and 2x range (from byz). You will need about 40 of them, and a few halbs to protect vs l cav.
Byz has cheap counter units, so he stays in base and defends with whatever is needed while the immortal elefants push across the map.
That strat might sound stupid. Thats because it is really, really bad and you will lose every game above maybe 1800. But it surely is still 100 times better than a 150 pop gold army crawing slowly across the map.
