Try to have the T1 Python upgraded to level 2 or 3, and seven of them trained by the time your reach level 5 (and your protection expires). Begin attacking other players as soon as possible, choosing ones hat are weaker. Three of your T1 Pythons should be enough to take care of one machine gun. Four or five should be deployed for two machine guns. All seven will be needed if there are three machine guns. Use the targeting option by tapping the machine gun and your troops will focus their fire on it. Use quick strikes on resource generating buildings. Even if you lose the battle, you may get some resources. Move all your troops together when planning the next attack. Take defensive buildings down one by one, instead of randomly shooting at them with limited troops. Use a grouping, attacking, regrouping, attacking cycle.
