Hearthpwn

For several expansions I've seen the evolution of this deck, which is of course supposed to be only for fun. However, I wanted to make a list that kept the fundamentals of the deck while actually holding its own against some of the decks on ladder right now. The way I did this is with the inclusion of some finishers for after you combo, Arcane Giant and Umbral Owl. I'm actually quite surprised I haven't seen any lists that include Arcane Giant, because it really is one of the big things that pushes this deck into the realm of being able to beat some decks. Jade Idol is also a win condition against control decks after you've already played both Yoggs.

Against any deck, you're always going to want to keep Gadgetzan Auctioneer and Witchwood Piper (which draws Auctioneer).

Against control you're going to want to look for Biology Project and Overgrowth in your opening hand to get to your late game as quickly as possible. Once you've played all your big drops, you can win through Jade Idol, potentially comboing that with a leftover Gadgetzan Auctioneer.

Against combo you'll want to keep Ferocious Howl and Branching Paths. This is certainly your weakest matchup, but the way you can potentially win is by milling them with Naturalize.  Also, if you can get them out fast enough, it can potentially be hard for a combo deck to deal with two Arcane Giants early on.

Against aggro, you really just want to be looking for Gadgetzan Auctioneer and Witchwood Piper. If you get to play Auctioneer on turn 6, then you will actually win most of your games against aggro, but unfortunately if you don't get it by then you have almost no chance.

Obviously this deck is not top tier, and if you want to climb you should look somewhere else, but if you want to have a lot of fun while actually being able to win games, then this is the deck for you. My winrate with this deck in wild legend is around 51%.
