This is my simple tactics..: If you're a little patient.. build your troops first.. My troops is goblin/succubus/dragon rider/magic cannon/frost giant/centaur archer.. basically your Hero will be tank when the battle starts.. lure the enemy leader with comet and send him at your base kill him with your hero with a back up of long ranged attacks and then just stay there using comets and clear enemies with the phoenix.. after u have full troops and spells ready or u think u can destroy the castle send all troops i mean all!! then when revenged attack comes it will be no use if u have freeze trap it will clear the first revenged with the help of magic cannon and succubus it will all fly away.. and the castle will be destroyed before 2nd and 3rd wave of revenge can come.. eventually always use comet to avoid bomber also magic cannon destroys bombers it will delay u a little cuz your troops will be send flying.. .. thats for me haven't tried cave of trial its just my second run ...
