This unique macro allows you to put each of your Blocks on separate mouse keys. For example, the first block will be set to the left mouse button, the second to the right mouse button, and the third to scroll the mouse up. 

After each shot, each block will shoot in turn with an interval of one second, which will allow you to literally destroy the enemy frame with the first shot. 
Thus, you will be able to effectively repel the attack of enemies and destroy them.
