well, way back when i played 3v3 or 4v4 games, i would play as UD and send an aco a bit distanced from the enemy base. Then i would build a few zigs and the enemy would notice and say something like wtf!? and well, it was fun because basically everyone would tp right to my new town center and own the hell outta them. Some games i would scout the base if there was an UD playing on the opposite team. if so, i rush in and build a few ziggs. then upgrade em. its good fun
