Eagle

The Eagle is considered by many as the strongest unit in the game. Its strenght isn't on the attack vale, but it's on the good movement cost, allied with the Catapult attack, that allows the Eagle to easilly circumvent the opponent's defenses.

Like almost all Combat Units with movement cost of 2 and Medium category, the Eagle has many advantages on one to one confrontation with Combat Units having movement cost bigger than 2. And it's Catapult attack gives it a great advantaged against units like the Kamikaze or Rain, that can be quite troublesome if not destroyed.
