Always Keep: Backstab, Deadly Poison, Kingsbane, Cavern Shinyfinder, Leeching Poison & Plated Beetle

With Coin Keep: Elven Minstrel

Keep: Fan of Knives & Blade Flurry

Aggro Druid (30 / 70) - Aggro Druid is the toughest match-up for this deck. It feels almost impossible to win. There is just not any way to clear wide boards with such high health minions when buffed. Surviving long enough to buff up your weapon for Blade Flurry is the goal. Sustain with Leeching Poison and Doomerang can get you through the rough turns. I have not played against this deck enough, but I can say it is an incredibly difficult match-up. Luckily it isn't super prevalent on the ladder.

Jade Druid (60 / 40) - Since this match-up is easier than aggro druid, we do not mulligan for it. You want to draw through your deck as quick as you can. The goal is to build a Kingsbane faster than they can build up their Jades. Save Doomerang for later in the game if you can, you want it to swing your health or push for lethal while still clearing big Jade minions. Greater Onyx Spellstone after Valeera the Hollow is key to winning the game when the board is flooded with Jades.

Keep: Eviscerate, Blade Flurry & Loot Hoarder

Midrange Hunter & Spell Hunter (60 / 40) - Your goal is to always make it to the late game, not go for face damage. Focus on killing your opponents minions with your own. Draw deep for your Blade Flurry for when they play their Greater Emerald Spellstone. When the time comes Kingsbane, Leeching Poison & Doomerang swing will provide you with the health needed to lock them out from winning.

Secret Mage (40 / 60) -  Your goal is to disrupt the secret mage as long as you can until you get your sustain on. Set up to always be able to take out Kirin Tor Mage. Putting Deadly Poison on your hero power if you do not have Kingsbane yet is a common play. Play Southsea Squidface or Plated Beetle if you suspect a Explosive Runes to minimize the impact. Figuring out how to play around Counterspell may be difficult. I would focus on getting rid of low impact cards first such as The Coin or Preparation when encountering a Counterspell.

Quest Mage (55 / 45) - Quest Mage is interesting as a match-up. Never focus on clearing their minions. Your goal is to buff your Kingsbane and push face damage as quick as possible. Quest Mage doesn't have many ways to stop your weapon from pushing damage. I have used Shadow Strike on my own Southsea Squidface just to buff my weapon for more damage. If you suspect they have lethal use Valeera the Hollow to go stealth to buy an extra turn.

Control Mage (60 / 40) - Fatigue the Control Mage to beat them. Save your Doomerang, Greater Onyx Spellstone, Blade Flurry all for taking care of Water Elemental. The worst thing that can happen in this match-up is getting freeze locked so you want to avoid that at all cost. Patience is a virtue in this match-up. Valeera the Hollow is a good way to escape from getting freeze locked.

Keep: Fan of Knives & Blade Flurry

With Coin Keep: Shadow Strike

Aggro Paladin (35 / 65) - By far the most annoying match-up and the match-up that kept me down the most while climbing. The deck is just so aggressive and goes so wide that unless you have Fan of Knives on the ideal turn things can get out of hand. You need the right answer, for the right turns. You want to try to hold off on Fan of Knives until after Call to Arms is used if you can. Shadow Strike is used on Corridor Creeper. Toward mid-game, once you hit Kingsbane, Leeching Poison & Doomerang you can generally quickly turn the game around.

Keep: Shadow Strike, Southsea Squidface, Lesser Onyx Spellstone & Loot Hoarder

Razakus / Anduin Priest (60 / 40) - Your main worry this game is getting one turned killed. This is the one match-up I will say that substituting a card for Evasion if you're seeing a lot of them will dramatically increase your chance of winning. Evasion will completely stop any kind of Burst from Shadowreaper Anduin for a turn. You want to draw and buff your Kingsbane as quickly as possible. Without a buffed Kingsbane you will not be able to sustain after the Shadowreaper Anduin turn. If you're going to play Loot Hoarder try to drop it when you don't have other minions on the board. Otherwise they will Potion of Madness it and steal your draw. If Southsea Squidface is silenced try to save a Deadly Poison or your second Southsea Squidface for the turn after you use Valeera the Hollow. This way you can double up later in the game for the one that was silenced. Late game you just push face damage until you win, using Doomerang if they try to burst you down.

Dragon Tempo Priest (60 / 40)- This match-up is difficult to navigate initially, but once you understand it will be much more easy. The main issue is not drawing fast enough to reach end game. Onyx Spellstone will be your best friend this game. It will help you clear big minions especially on the Spiteful Summoner turn. Don't be afraid to use Onyx Spellstone before it hits 3 minions. You do generally want to save at least one Onyx Spellstone for after you use Valeera the Hollow. Late game your Kingsbane should be all that is needed to keep control of anything they can play.

Big Priest (60 / 40) - Big Priest is probably one of the funniest match-ups. It feels amazing to just slay huge minions one after the other. As long as they don't Barnes out Y'Shaarj the match-up is incredibly winnable. By the time they cast Shadow Essence you will already have minions on board or a Shadow Strike to kill the minion. After you should have more than enough removal to keep killing their big minions. When Y'Shaarj is summoned is when I avoid clearing the board initially and go into Valeera the Hollow. Having them summon more minions to set up for a bigger board clear with Greater Onyx Spellstone or Blade Flurry.

Keep: Fan of Knives, Shadow Strike & Lesser Onyx Spellstone

Tempo Rogue (50/50) -  Tempo Rogue can have some crazy starts. If it wasn't for huge early game Edwin VanCleef or double Prince Keleseth starts this match-up would be much easier. Some games are just over from the start from sheer luck of the draw. However, games which aren't over from the start are incredibly winnable if played correctly. Always try to minimize board size and use Onyx Spellstone as a last resort. You want to have the board completely clear on turn 6 to prevent a follow-up Bonemare on turn 7. Shadow Strike will aid in dealing with Corridor Creeper and Cobalt Scalebane. Late game it is all about clearing the board with Onyx Spellstone and Kingsbane & Doomerang combos. 

Mill Rogue (50/50) - If you realize your opponent is a mill rogue do not try to draw. You want to focus on doing your best on holding off on buffing your Kingsbane until you have already used Valeera the Hollow. You never want your opponent to have a stronger Kingsbane than your own. Eviscerate will aid in obtaining lethal late game.

Keep: Backstab, Fan of Knives, Blade Flurry & Loot Hoarder

Shaman is a class? Anyways, they all normally go wide. We mulligan for wide boards and it is generally pretty easy to keep up. Control Shamans are just laughable against us late game.

Keep: Southsea Squidface, Lesser Onyx Spellstone & Loot Hoarder

Zoo Warlock (55 / 45) - Zoo warlock is not that prevalent on ladder right now. Even though we do not mulligan to beat them, they are easy enough to beat regardless of that. Just draw to late game and use your removal efficiently to clear minions. You will need leeching poison as quick as possible to survive any damage.

Cube-Lock (65 / 35) - One of the best match-ups for us. The main idea is to out control Cube-Lock. I generally end the game with extra removal left over. This game is all about draw, draw, draw. Your minions will aid in destroying their threatDoomguard and Voidlord. You want to save Doomerang for destroying Doomguard behind taunts. Most games you lose will be from getting burst down completely randomly. You're playing for the long game. Be patient and don't use your Greater Onyx Spellstone the first chance you get. Save it for the moment that you actually need it to survive the following turn. You always want at least a 9 attack Kingsbane by late game. 

Rin Warlock (70 / 30) - Rin Warlock is easier to beat since they do not have the burst like Cube-Lock. You want to hold onto Cavern Shinyfinder and Doomerang as long as you can for late game. You will always be able to draw your deck out before Azari, the Devourer drops. The trick is keeping your weapon in hand and not in deck so they can't destroy it at that point. You should be able to kill them before coming close to running out of Kingsbane charges though!

Keep: Fan of Knives, Lesser Onyx Spellstone  & Loot Hoarder

Warrior is a class? 

Pirate Warrior (45 / 55) - Pirate Warrior while not impossible is not nearly as strong as other aggressive decks in the current meta. Most warrior decks are also control at this time, so the mulligans are built more toward control over Aggro. Against Pirate Warrior try to avoid taking face damage as much as possible. Even if it means using removal in-efficiently, it is worth it. Pirate warriors tend to run out of steam faster which allows us to capitalize on their lack of threats compared to other decks at this time.

Control Warrior (65 / 35) - Control Warrior is interesting since at this time they can generate infinite value through Dead Man's Hand and Woecleaver. By the time they get to late game we already have our Kingsbane ramped up though. In general, using our Kingsbane and Greater Onyx Spellstone is enough to take out their threats and push for lethal.
