Hey I got all the basic decks from the quests etc i bought some expansion packs, normal packs, etc. And i have a lot of resources to craft.. What are the best decks in the game atm. So what should i craft? btw any good guides for this game? I found this. But it doesnt look much updated. So what would u guys recommend?
