Advice on Machaka appreciated

[Pirateiam]

Here is my Machaka strategy:

Create a typical Main army just like some of the posters have explained but also creat a 8-10 equipped assassin army also. Keep this group in front of your main army and just before you main army strikes set them to assasinate. The assasinations take place before the armies fight. Even if you are only 50% succesful taking out 4-5 commanders or mages can cripple an army that has to fight right after that.
