Hearthpwn

The most annoying deck you will ever play against. Currently rank 3 in wild.

Great matchups:

Everything aggro incl. Paladin, Shaman, Token Druid, Face Hunter, Secret Mage. You need some real terrible draws to lose one of these games. Use Grove Tender for mana so you can spreading plage and AoE earlier.

Win Condition: Fatigue.

Good matchups:

Razakus Priest, Cubelock, Maly Druid. All these decks have to draw a lot especially in the early game and unless all your card draw is in the last 10 cards you will just mill all their important stuff. Once you destroy one or more combo pieces (Raza, Anduin, Spawn of Shadow, Malygos, Aviana, Kun, Mal'Ganis, Cube, Doomguard) you can just outheal them. If you know it is the Naga Sea Witch cube lock hard mulligan for poison seeds. If you get it you win, if not you'll most likely lose. Great game design, Blizzard.

Win condition: Mill, fatigue and armor.

Mediocre matchups:

Dragon Priest, Silence Priest, Recruit Paladin and everything else midrange or relying on deathrattles. The problem is that druid has no powerfull removals for high health minions so you have to be very careful with your removals.

Win condition: Fatigue.

Terrible matchups:

Control warrior, especially when they play geist because fatigue is then not an option.

Win conditon: opponent disconnects.

Big Priest, even though I'm still 50:50 this matchup is terrible. You don't want to give them cards unless you can mill at least a few cards. Be super greedy with your removals and use cards like feral rage to remove their big stuff. Always keep poison seeds for their spellstones and keep track their resurrects and eternal servitudes to know exactly how many removals you need. Kill smaller minions to make their resurrects worse.

Win condition: Survive somehow.
