I've been working around a combo where I get out 4 dreadsteeds, then play either 2 undertakers or knife jugglers, trade my 4 dreadsteeds to proc the abilities 4 times each then play a belcher. The next turn I then trade the 4 dreadsteeds again and then play a dread infernal, which procs the abilities on the knife jugglers or undertakers another 8 times. With 2 undertakers they become 14/1 each with playing the belcher the previous turn too. You get even more value out of the knife jugglers if you get lucky and hit mostly face. I've built a deck that revolves 100% around dreadsteed and it's working so incredibly well with the absolutely stupid draw I get off of cultmaster. There is a trick to making a deck revolving around dreadsteeds viable though. Sacraficial pact and sense demons with only 6 demons in the deck. You will always have a dreadsteed, sense demons makes it so I always have both dreadsteeds and Malganis before turn 6. Sacrificial pact is a crap card but it's the only life gain and Baron Rivendere will only live 1 turn most times, if you have a sacrificial pact in hand with a mortal coil or power overwhelming you are able to get up to 4 dreadsteeds in one turn if they have at least a 1 damage minion on board and the moment you have 4 dreadsteeds you have as much card draw as you could possibly hope for. The absolute worst case scenario is not getting baron until late in the game, but with 2 dreadsteeds and worst case scenario using a faceless manipulator to make a third it actually seems viable with every card added specifically to combo with dreadsteeds. Reading this I realize it seems like a stupid amount of set up, but I've only lacked dreadsteeds a single game and was able to pull through anyways with the value from baron and kelthuzad. Alright that was much longer than I expected I should have just posted a deck list.
