I had a lot of fun games with this deck soulwarden is such a fun card and Reckless Diretroll you can really choose what cards you put into the discard one of which i love to put is Mountain Giant and if your are just lucky with the doomgaurd drop or you are able to throw down Soulwarden with the other Reckless Diretroll the infinite loop starts to fall down hard. Also with Cruel Dinomancer the deathrattles really add towards Da Undatakah with either pulling out 3 cards from the discarded pile or just plain putting up taunts through Voidlord the relaxation starts to kick in.
Try this deck out loads of fun.
