Same problem as the other two: Too easy. All you do is alternate sending a swordsman and an archer down one lane, and then once a unit gets all the way to the other side you keep sending swordsmen.
Too easy. Spam halberdier/random strong unit and then an archer, repeat this on one lane until your units start getting to the other side, then keep spamming halberdier/random strong unit. GG mate.
