Poll... Witch Ability: Illusion
Witches would have a secondary tap ability to be able to one time during battle create multiple illusions of herself that keep an opponents defenses confused for a short time as to which witch is the real witch. The illusions do no actual damage to the opponent only distract temporarily. To even it out, the enemies defenses could still target the real witch if she moves into its atk range first. However the illusions don't disappear by killing off the witch... the illusions would remain until either the enemy defense realizes it's an illusion or till there are no other usable units the attacker has (obviously).
