Defensive Strategy
Healers do not last long if she is in range of a Single-Target defense or an Air Defenses, so make sure you upgrade and protect your Air Defenses as much as possible. Put your Air Defenses in the middle of the base to prevent ground troop like Giants from destroying it quickly.
As of the 24 February 2015 update, the strategies to defend against Healers involving Traps placement no longer work, as Healers do not trigger Traps anymore.
