ok... 1st of all make sure u have comic (RECCOMMENDED) equipped or a differant attack spell (make sure it has quick wait time) (EXTREME IMPORTANCE) now have a balance of Gr8 units and weak units that spawn quick when u enter battle build your units until enemies get close(ish) and by now ur spell should be ready use it on their hero and forward ur units their hero should die quick (IF U HAVE THE BALANCE RIGHT) then get close to their castle and the remaining units u have built up forward them and their castle should be down quick(ish) THIS DOES NOT WORK ON CAVE OF TRIALS BUT SHOULD WORK ANYWHERE ELSE IT HAS ALWAYS WORKED FOR ME
I always found that you last as long as you can with arrow and goblin spamming whilst saving up for the best guys you have. You wait until you have full of all guys (goblins optional) use an attacking spell on the enemies' boss so he starts running at you and then you unleash your full blast on him.
