Hearthpwn

This deck is midrange, so you have to manage your board in different ways for each match.

Match-ups:

mech Paladin:

This match can be very complicated, but in gerenal it is very simple you keep cards like Aldor Peacekeeper, Keeper of Uldaman and Zephrys the Great this make this match very easy, you play minions and trade, you have a lot of heal and taunt to protect you, you better wait for him magnetize the minions before playing the debuffs.

Secret mage:

With a lot of healing and good minions you will play in a more defensive way making trades when necessary, since mage has many ways to deal direct damage count on them Eater of Secrets is one of the best cards agaist them, if they have a slow start try to play more aggressively, Eater of Secrets and Zephrys the Great can help you to find lethal agaist a possible Ice Block

Renolock

There is not much to do in this game you have to play aggressively, you cannot gain value against them and you will hardly win this match

RenoMage with Quest

Just like Renolock, They have a lot of RNG and ways to stop their Progress with very annoying OTK, Zephrys the Great is essential for this match to speed up your pace, or find lethal, stay smart against the Ice Block, Bad Luck Albatross can stop some draws and the reno.

Mecha'thun Warlock

This game different from the other is very simple, you will play normally since the opponent has slow plays focused mainly on draw, Bad Luck Albatross possibly has the most important role in this game, since most seem unaware that is prevents the combo from happening if you play when the opponent is doing the combo possibly you win that game, or at least delay your opponent enough to find some way lethal

Pirate warrior and Rougue 

Another easy game, your minions have better status, so making trades is not such a big loss, if you have Reno Jackson it could mean instant victory, and in late game your big boys will do the service, so its very important that you have a low curve in these matches, this applies to any fast and aggresive deck.

Priest 

the Priest has some archetypes big and Dragon, Against Big you have to make a quick game if you manage to be aggressive enough i should be enough, against Dragon making trades is very importante since the Divine Spirit Inner Fire is very dangerous.

and that is for now, if you have any tips you'd like to give or have any questions, just comment.
