Kings bane should be obvious enough. Cavern shiny finder to draw kings bane. Evasion to stall on a really big enemy board. Elven minstrel for card draw. Betrayal is good for killing wide paladin boards and token druid boards.
A fun deck built around kingsbane. Lots of weapon buffs, cavern shiny finder and countess ashmore to draw kings bane. Furnace fire colossus for a huge late game minion. Some card draw and minion destruction cards. All of the good stuff.
Furnacefire is sooooo bad tho
but, with kingsbane, if you play it near the end of the game, you can get a huge minion, and then just draw it again
