I am level 30. I can't beat Laiken and Razakel in Hall of Echoes arena. Should I first attack the Dream eaters or the two of the them? I use the Summon Ghost level 10(because he heals me) and my creature for defense, and Fireball level 10 and thousand strikes level 5. Laiken (or maybe Razakel) uses the spell that inflicts around 1500 damage to me, and that is an attack that i can not evade.
