It's completely beatable, you just have to do it fast, before he manages to boost these to this level of str. I personally play this deck too and got injuried a lot with weather for example. Also I try to split str between more cards, since everybody wants to kill my hawekar support with scorch.
It's possible to defend your hawekar support with the Idaemam card, so one special card will not kill them, and there is need of two.. but still.. beatable, piece of cake.
I see an issue with monsters. I play the deck with HS and there is no chance at all to play against monsters, because they always starts with geralt or eredin and then pass. This is such a big advantage, gold cards should not be able to stay on the battlefield to next round. This is OP since golds are invincible with most decks (just Northern can degrade it to silver).
