Dervish

Strategy

 * Don't be afraid to use your Dervishes aggressively because they disappear at the end of the turn.
 * All Dervishes are affected by Fireblaze and Windstorm Obelysks' buffs while the Obelysks are still alive and undispelled.
 * Windstorm Obelysks can be counterproductive because the extra point of health they give wind dervishes mean that the wind dervishes are more likely to block each other from attacking.
