Van vs Valkyrie

[Saber Cherry]

Use "hold and attack rear." The enemy squads will advance, leaving the leaders, mages, and archers unprotected at the rear, and then they will be surrounded by flying units and die... unless the enemy does something unexpected. But it usually works. I even got massacred by Mictlan Eagle Warriors (which are really weak) once because I was not expecting them, and my superior army routed with no leadership.

You can also do "attack archers" ... sometimes people hide their leaders in a block of archers.
