Load the goliath,tank,and one cloaked ghost in the dropship. Unload the dropship somewhere in your enemies base(Not where detectors are). Then bring the other ghost outside the entrence of your oponets base. Make shure he stands still and doesn't die. Then nuke somewhere close to the entrence of the base. Then say crap i forgot i cloaked my ghost. Then they will probably kill the ghost thathat is not cloaked outside the entrence of their base and think thethey killed the ghost that is nuking.

CreepColony's Opinion: Yeah it will work as long as they don't know you don't have a cloaked ghost in their base.
