So, first of all, in starting handtry to leave the cards that can draw Kingsbane, like Cavern Shinyfinder and the Raiding Party. After that just buff your weapon with cards you have.
For more late-game, the keey card is Kronx Dragonhoof which you can copy a lot of times with the Shadowstep, Potion of Illusion and Togwaggle's Scheme if you had it in early game.
