The Combo

1- Play Uther of the Ebon Blade

2- Use your Hero Power, and bounce back the Horseman with either Youthful Brewmaster or Ancient Brewmaster.

3- Hero Power again, make sure the Horseman isn’t the same one as the one in your hand. If it is, you’ll have to wait one more turn and try your chance again. If it’s a different Horseman, then bounce it with either Youthful Brewmaster or Ancient Brewmaster too.

4- Make sure you have 10 mana. Play the two Horsemans in your hand, play Garrison Commander, and Hero Power twice to perform the OTK.

Notes

– Gluttonous Ooze (if you face decks with weapons) or Eater of Secrets (if you keep losing to Secret Mage) might be good tech options.

– Cards that could be considered: Righteous Protector, Forbidden Healing, Hammer of Wrath, Crystalsmith Kangor*, Spikeridged Steed, Nozari*, Acolyte of Pain, Loot Hoarder, Bloodmage Thalnos*. I’ve found this version of the deck the most effective. *I didn’t add these Legendaries because I wanted to keep this deck relatively cheap.
