pre to nano ( space ) pocket  bronze

as soon as you hit bronze you need to upgrade gold and iron mining along with towers and if you have mass food
tribute some to your wing so he can build up a lot faster to better help you survive

you will need to build a few seige factories at your wings base, you provide the catapults while he provides
the infantry for attacking, you need to attack the enemy wing forcing the rest of his team to come to his aid
and use up their resourses in doing so, 4-8 catapults should be fine and dont take a lot to make, try to stay
behind your wings army and if you see army trying to kill you, run your catapults back behind the wall and 
regroup for your next attack
