I figure this would be an interesting excersise.
So this type of deck will only have 20 unique cards in it.
60 card deck.
* Note: the Streets are an exception, if 1 of each is put in... they can then have 22 unique cards.
OK so vote: 10 characters, 5 resources, and 5 non resource non character cards.
For me:
Charachters: Wex Pyke, Tarle, Alannys Greyjoy, Victarion Greyjoy, Wendamyr, Vale Refugee,Herald, Carrion Bird, Fishwhiskers, Harbor Thug
Resources: Streets, Gatehouse, Sea, Red Keep, Chambers
Other: To Be A Kraken, Risen from the Sea, LIV, Support of Harlaw, Scouting Vessel
If you notice... this is very hard since we all like to put 1x or 2x utility cards in a deck... but this does not allow for that.
