If you want to defeat colosus ..... you must build a wall at his back leg ....If you do that right it will can't hit the wall ...... this will give you the time to hit him ......use the magic units because it's weak vs the magic and use a powerfull unit like black dragon to kill the enemy's small units.... this will take a time but it worked with me.........
