Like 100 Mayan plums + the odd siege rams fighting both sides of the map on a 4v4? *cough cough* *cough*
That's a nice army you've got there buddy; wouldn't it be a pity if a couple of siege onagers came along and flattened it all?
Those are some nice onagers you have there, wouldn't it be a pity if some eagles/hussar/paladin/mangudai/other onagers came along and and killed them??
