Tactics for playing as the Sylvan faction.

The Unicorn helps against melee and some ranged units. Its tent heals: for example, with one Unicorn, you can easily defeat a horde of Gremlins. Elves are not only strong with archers; they also have swordsmen, druids, and Ents. If we talk about the early game, archers are definitely needed, but you'll quickly run out of wood. However, what else can you do? Upgrade the archers, and if you have enough resources and wood, upgrade the swordsmen with Wind - a mobile tank with a super ability. I once played as an Elf on the "Contested Island" map. My hero was Gilraen. After the Phoenix, I noticed a "Darkness" skill in a remote area and decided to take it, even though I waited a long time. The result was defense, leadership, darkness, and racial skills - not bad! The computer was probably surprised when I subdued it, and with the druids, I raised spellcasting to 13, so it wasn't just for show. And the darkness spells were really effective. The "ironclad" swordsmen wiped everyone out - that's it!

...but you can't attack archers and mages anymore, so it's better to take Ossir - he has at least more archers....

There are more archers, no doubt, but an extra support unit won't hurt, especially since what idiot would attack archers (not upgraded) with mages or archers? It's better to conquer small groups first and then, after a week, organize an expedition to the mines.
