Counter-heroes in duel mode (3.1).

Anwen vs. Ossir Ossir's defensive strategy against Anwen doesn't work – it's been proven: diamond dragons in the center eliminate all archers in the first turn. Then, Anwen, with her magic, simultaneously attacks (Magic Dart, preferably with a slowing effect) and heals (Regeneration on ents and unicorns). Anwen's druids are generally ineffective due to their small numbers; they are only needed to transfer mana to the hero. The ents and dancing with death/wind creatures first eliminate half of the ents, then all the unicorns (by this time, your unicorns should have finished off the ents...).
