The monks will have lower speed. The mage will have higher speed. Sometimes you have fewer angels than your opponent. And there are also crusaders. They are the ones who will deal with them. Although the angels will be dealing with the monks, and the crusaders with the angels. :D
It's unlikely that you will have both crusaders and monks at the same time... and the angels can be killed with squires or spearmen. And it's unlikely that the angels will be able to reach the monks right away...
:D :D
