Tactics for playing as the Sylvan faction.

It won't be easy for the Elves against mages. After all, they have 3 ranged attackers. I think the best approach is to develop skills in Light, Leadership, Defense, and Attack. And somewhere along the way, find a way to increase Dodge, otherwise, the archers will fall after the first shot from the Titans.

Actually, it's easiest for the Elves to play against mages. So what if they have 3 ranged attackers? Mages have very low defense, and their troops are generally weak (unless the game is very long and there are 3 mini-arts). Even if there are 1-2 mini-arts on key stacks, such as Golems and Titans, it won't save them from Luck and Blessed. With Tap Shoes, Dancers, Fairies, Battle Rogues, and Dragons, they can reach the archers in one turn.

If you take Wing and add mages to the Blessed, (I think they are more dangerous than Titans, even if they are not as strong), then these mages won't even be able to fire, and you can also manage to inflict significant damage on the Titans.

If you take Wing, nothing will save the mages:), because the mages' entire hope is not on the Titans, nor on the mages; in general, the mages' troops fall apart quickly. The most important thing for the mages is the hero, but against Wing, the hero won't have time to do anything.

If Elves are fighting against mages, then you can take Chaos --> Magic Resistance, Defense --> Dodge, and then develop skills in the following order: Light, Luck, Leadership (Logistics).
Or take Attack --> Archery.

I wouldn't take Chaos against mages. Their troops have good magic resistance, and they also have mini-arts that reduce magic damage. You need to focus on attack to quickly eliminate the troops. It's better to take Attack, Light, Luck, and Leadership (for the aura), and Logistics.
