Small, but sometimes important, tactical tricks.

Let me explain. For example, the opponent has 75 fast units. And you have 50 Furies (beasts), but you need to eliminate the opponent's archers. You cast "Haste" (if you have it) and use the trick I described above. And that's it! Since Furies aren't very durable, you save them and put them in a position where, essentially, almost all of the opponent's units will be under attack, and you choose which of them will survive the turn and which won't. :) :) :)
