After watching top battles to see how it's like to play with Prince Renynn l realized that it's too powerful summoner. When you use this summoner together with Flesh Golem it becomes extremely hard to kill Flesh Golem because of the tank healers, high health, self heal. Also your range monsters will have 1+ range attack which is another great advantage of this summoner. Though it's a powerful summoner you can win him easily with your 2-3 summoners.
