Any dragon can be beat, but of course strong dragons are much more difficult. First, head over to the battle calculator and enter in the opponent dragon and its level. Find the dragon that you have that has the strongest chance of winning and choose that dragon.

Pretty simple, right?

In cases where you do not have any dragons strong enough (ie. all your dragons have a 10% chance of winning) then my strategy is to use any level one dragon since I want to keep my stronger dragons healthy for upcoming battles. I've won against really strong dragons with a level one dragon many times, it's just a matter of luck and perserverance.
