@Oatmeal Shudderwock? He's pretty fun. There's a seemingly pretty effective OTK deck with Saronite Chaingang + Lifedrinker + Grumble, and I think something else. it's pretty great since it will make you really hard to kill and give you a high probability of winning even if the combo doesn't OTK, which is good because it seems the order of Shudderwock's copies are in a random order every time. I made a variant of it in Wild that uses C'Thun cards and Reno Jackson, it's pretty nutty. I don't think he'll stay popular forever, but he's practically a Yogg, and can literally become a Yogg if you play Yogg before it. So that's fun.
I'm tempted to build this list, I think I'm only 3200 dust off from it, which is fine, since I have 5700+ atm with something like 20 packs to open. I theorycrafted it during spoiler season, I'm sure it's far from perfect but it looks a lot of fun on paper. Over half the deck is draw, removal, and stabilization, and the rest is just ways to burst. Not 100% sure about Thaurissan or Woecleaver or the lack of any Brawls but that's an easy change to make. Don Hon'Cho might be worth adding in just for the combo with Leeroy + Inner Rage + Sudden Genesis.
