There are definitely good chances. If, for example, Wing + Osiris appear, a good start is guaranteed. Without losing anyone, with enough time per turn (5-6 minutes+), and after acquiring the planned skills, they can give it to the undead, whose progress isn't going so well (they messed up skill 10, they messed up skill 20, they gave the wrong skill - the undead become much weaker). The secret to the Elves' success lies in the implementation of archers. The second week should be entirely dedicated to finding resources for building (although we're always looking for wood and scouting for it on day 1).
