Angels and paladins – how to use them? There are also discussions about them here.

:) Well, it's like saying, "all units attack, bang, boom, hurray!" and victory=))
And how many of these horsemen did you have?=) Against them, it's better to use Knights of Isabel, as you need to eliminate the enemy as quickly as possible before they overwhelm you with magic (and in general, when you have a decent number of horsemen (20 or more)) and the enemy isn't a die-hard Berserker fan, then only Knights are the best choice (by the way, if you already have Anti-Magic, then it's the same, only Knights).
