I think that when playing as the Elves, the main thing is to play without losses, and for this, you need to carefully plan your attacks. Here, it is important to focus on speed and initiative. For example, if Hydras reach the enemy on the first turn, the Lizards that are already behind the enemy lines will bite not one, but several opponents. The same applies to the double attack of Minotaurs. Pin down the enemy and use a wall of fire with an upgraded Pyromancy skill + bite + fury. If you invest in attack and mass acceleration, the initiative of the Furies will be 25+, the unit is fragile, so you need to try to use it as much as possible, and so on. Dark Elves are a delicate matter; I'm experimenting myself. Good luck in battles! :)
