What are we doing with this deck? Well, the answer is simple! We are drawing ourselves out and swapping decks with our opponent using King Togwaggle. The catch is, with the advent of Descent of Dragons, we have a new card to make this even more degenerate! Murozond the Infinite! When our opponent plays their Ransom to get their deck back, we play Murozond! Then, once they've lost all hope, we watch them concede or (sometimes) fight for our life in a war of attrition!

Tips:

Against Aggro: Always keep Loot Hoarder, obviously, but against these types of decks it doesn't hurt to keep a Spirit Lash or Holy Ripple. Bloodmage Thalnos isn't a bad keep if you have one of these alongside him. 

Against Control: Penance is a surprisingly strong card to keep to control the early/mid game. Your goal here is to draw out as fast as you can, saving Psychic Scream for only the most dire of situations. Finding and dropping Hemet, Jungle Hunter as fast as possible will have your opponent reeling in self-pity.

Against Midrange: Your toughest matchups are midrange decks. You need to know when clearing minions is essential, and saving Psychic Scream for the most opportune moment is key. Bloodmage Thalnos and your board clears are going to be the most important finds in the mid-game, but if you find yourself close to your combo you may want to commit. Remember, swapping decks is great, but if you have 20 or less life and they have a board it's going to end badly.
