Infinite Knife Throws

Use both of the Deathspeakers to give the Necrotic Geist and the Knife Juggler immune, then play Lord Godfrey to give infinite knife throws, as long as there is a minion that Godfrey can kill with his battlecry. You can use Emperor Thaurissan to decrease the cost of the combo in your hand. You need a total of 11 decreases. Another way to trigger the combo in a better way is to use Grim Patron.
