I’ve been trying to look online for ideas for decks, but all of them assume you buy 3 core sets.

I am not doing that.

I do have some other packs, would anyone be so kind as to help me come up with a deck using what I currently own?

Core x1
Wolves of the North
Lions of Casterly Rock
House of Thorns
Taking the Black
The Road to Winterfell
The King’s Peace
No Middle Ground
Calm Over Westeros
Across the Seven Kingdoms
Called to Arms
There is My Claim
All Men Are Fools
Guarding the Realm
The Fall of Astapor
The Red Wedding
Obyern’s Revenge
The Journey to Oldtown
Kingsmoot
Pit of Snakes

I was trying to use this: https://thronesdb.com/decklists/find?faction=&tournament=&author=&name=&sort=popularity&packs[]=1&packs[]=8&packs[]=12&packs[]=24&packs[]=2&packs[]=3&packs[]=4&packs[]=5&packs[]=6&packs[]=9&packs[]=10&packs[]=13&packs[]=17&packs[]=19&packs[]=20&packs[]=21&packs[]=22&packs[]=28&packs[]=27&packs[]=43#allowed_packs

But it seems like every single one assumes you have 3 core sets, and I am just not doing that. I have plenty of cards as is, and I’m not looking to join any tournaments, I’m only going to be playing with friends and want something simple as a new player of what to look for, for synergy and deckbuilding education, so I don’t need decks that are like “this deck won the world championship” kind of stuff.

Thank you for any help!
