This Works TOO often

need to be in team game

and Enemy purple is really strong and enemy green is very weak

sayTO ALL lets go attack green he is weak right now then purple moves at least half of his force closer to green then go and attack purple DIsinformation is the best.

CreepColony's Opinion: You can also say TO ALL early in the game "I am going mass muta" and make them make tons of air defense, and then go mass hydra instead.
