     Mulligan Guide: Omnotron Defense System is a pretty challenging encounter. He will very quickly ramp up and put all of his bots on the board. I normally don't like combo decks, but this one is by far the cheapest and most consistent deck I've used to defeat this boss. Your most important card is Gadgetzan Auctioneer and you should hard mulligan for him. It's also pretty important to have either Innervate, Wild Growth, or a Jade Blossom to ensure that you can start drawing your entire deck before he puts out Magmatron and you kill yourself from playing cards. The only games I lost against this boss were ones where I didn't draw the Auctioneer.

     You've got a couple of pieces of removal in this deck, but they really aren't important. In fact, it matters very little how much Health you have because as long as you have the Gadgetzan Auctioneer you have the potential to gain a HUGE amount of armor from Earthen Scales and Feral Rage when you're drawing card after card.

     The whole key to making this deck work is major abuse of Electron. Once you can cast Gadgetzan Auctioneer you will be able to fill your board with tokens, buff them, and draw your entire deck. In most cases you should be able to use both Savage Roar and kill him on your next turn and there's absolutely nothing he can do to stop you.

     If you don't draw the Auctioneer or at least get one before turn six, then you just need to restart, because there is absolutely no way you can win otherwise.

 

     I've kept this deck as cheap as possible and don't suggest replacing anything. If you absolutely have to switch something just use any spell that costs 3 mana or less. Do NOT add any additional minions.
