For example, when BM dismounts the machine gun, the clone goes over and controls the enemy's machine gun T (stuns) your image. Then BM either teleports over and spins directly, or runs over and spins. This way, the machine gun won't be able to stun you, allowing for better synchronization with the machine gun.
Also, when AM uses 30, you can first summon a water elemental, then control the enemy’s machine gun T to stun your water elemental, after which AM can cast 30 without being interrupted by the machine gun. In short, the stun from the machine gun is very important.
Now that everyone knows the shortcuts, they can use them more effectively. There are many more small tricks to explore as time goes on.
