How come the hsreplay stats suggest this an average deck? It seems to perform poorly versus druid and paladin.
Sample size is pretty small. I found the deck by looking for the top 4 popularity decks at diamond 4 in Americas on HSReplay. That showed Libram Paladin, Stealth Rogue, Bomb Warrior, Guardian Druid. That covers like 37% of the match ups. Then I looked in the match up part for a deck that had positive winrate vs all 4 or close to it. I found this while looking at that. The stats definitely show it doing poor in those match ups, but obviously that wasn't my experience. The Paladin match up probably poor, in that match you really want to go first and then control the board the first 6ish turns, then use Blade Dance with big attack to clear giant shit and go face for a lot. Going second makes the match a lot harder, but not unwinable. You really just want to keep the board clear on their side so that they can't effectively buff.
Bomb Warrior is mostly just about timing things out and just efficiently using mana to max damage to face. That's a match where you really need a good macro plan on how you get their. Polk shines in that match. Priest is a lot like this as well. You're just looking out a few turns and figuring out how to burst them out over 2-3 turns.
Guardian Druid was never really a hard match for me. You can get a pretty good early start, Blade Dance if they get taunts/draw guy.
Stealth Rogue you basically just control the board and out heal them by getting a lot of healing on warblades with twin slice/lapidary. This is pretty similar for the Shaman and Mage match ups.
It boils down to you can set up some pretty nasty 2 or 3 turn kills that are pretty hard for them to stop, especially when you save Magtheridon for a board clear. Shit, I even had a game vs Big Warrior where I went through a divine shield ruffian guy, and 2 of the 7/7 taunt deathrattle another 7/7 taunt and had damage to spare. It's definitely not an easy deck to play, and if I wasn't playing out of my mind I probably easily lose 7ish of those games. /shrug
I also think for this deck their is a learning curve on people playing the deck well. People not knowing what to do with Magtheridon, people not knowing how to piece together kills over multiple kills, people killing things they don't need too and wasting cards, people going face when they should be clearing etc. If you look at just legend for the stats it gets a lot closer in most of the matchups. Though I honestly can't say why there is such a disparity in my experience vs Druid and what the stats say. Maybe just variance.
