Miasma:
The thing with the Norse is even though they mostly start with Block they’re not that strong in the bashing game. Most players have AV7 so its fairly easy to KO the players. Also the Berzerkers and Ulfwereners have Frenzy so it can be fairly easy dismantling a cage for the running game. Use your CD blockers and Bull Centaurs to grind it out if you get the chance score with your Bull Centaurs if not at least a Hobgoblin and hope for Dirty Player skill at the game end
