Counter-heroes in duel mode (3.1).

More replays. As it turns out, Deleth from version 3.1, who isn't exactly a weak hero, can put up a fight against some. For example, Shaq initially has to deal with Imps, not Devils. And Ravenne rarely manages to do anything against Anwen; in this case, she was lucky with the Vampires. They weren't enemies and spawned almost every turn.
