So this is a deck anti meta doing good against most enemy leaders even Usurper.

There are some nasty classic combos here:

Olaf --> Knut (Butcher can be played with Knut if you feel safe)

Dagur --> Harald // --> Regis (can have Greatswords prepared)

Kambi --> Mrkvarg (Endgame closing combo)

Regis --> Greatswords.

Houndsnout --> Priest

SWAPS:

You can swap Undying Thirst with Spearmaiden (for some straight set up damage) or Samum if you want better set up options for Regis and the greatswords.

You can swap disgraced Brawler with Dimun Warship.

Try to lure the locks and the traps with the longships or the priests so you can have your strong combos unspoiled. Or even try throwing a Greatsword, its ok to sacrefice it because Dagur --> Harald with 1 greatsword in addition is a very strong combo

Play smart with the card advantage, if you have to play a card to win a round throw a protector, a priest, a longship or a fanatic.

Use Protector mostly between the longships.

If you are behind and want to catch up a round just play (Royal Degree if you don't have both) Olaf and Knut or Dagur --> Harald

I also included Fanatics among with the totem if you face an aggressive enemy.
