I’ve been using the megatheriums and I’d just like to say never use them for the dragon, I had a full team of megatheriums with 10k hp and around 520% melee and they got demolished I thought it would work because of how quick the broodmother went down but no the dragons ranged fire is to much so megatheriums are not good for ranged battles but if you do want to use a megatherium bring a flyer that can pick up a megatherium and drop it on a enemy in pvp
