I reached rank 2 with this deck , playing it with a 74% W/R out of 73 games 54/19. It is a tempo Control deck with a whole lot of value in it , it wins against everything except OTK decks , which are winnable but you need to have a bursty hand , I have a 50% W/R against them. This deck wins 90% of Midrange matchups and losses the other 10% to lucky draws and a bad hand. Aggro is easier to win than expected , 68% W/R against Pirate Warrior , maybe one of the only matchups in which Reno is valuable , other aggro decks are not a problem , except a very interesting aggro Paladin which ran 2 Deathlords .

The main Win condition is attrition for sure , this deck plays very well on curve and sticks on the board very easily , of course the best way to win is the Shadowreaper Anduin, Raza the Chained combo (which I will call Shadowcannon from now on) , hence comes the name . One of the best cards in this deck is Elise Trailblazer,  it is a 5 mana add 6 0 cost cards to your hand with Battlecry deal 2 damage , and that is without adding how much value you get from the best set of cards in hearthstone , even if you get shitty cards or lower cost ones that do not give you that much of the desired value , you get 12 damage for free +4 from summoning her.  I chose her over Lyra the Sunshard because even though she is basically infinite damage on her own and another spell , she can make you clog up your hand , especially if you save up cards for her , replacing Elise for her should only be done if you face Fatigue Control matchups which are not common.  Another possible replacement for her might be Recruiter, it is a 5 mana inspire mechanic card , if you have drawn your Shadowcannon Combo it is a 10 mana 14 damage combo . 

Another good card that saves most games is Obsidian Statue , best card against control  decks , usually Entombed by Priests because they cannot deal with it , which is their biggest mistake , not taking the Sylvanas is commonly really bad .I run Stonehill Defender just to get a second one , or against aggro , a Tortollan Shellraiser .

Another combo is Shadowcannon and having Brann Bronzebeard and Kazakus , ( bonus points for saving Radiant Elemental and Maybe a Power Word: Shield ) for a burst of 16 to 20-22 damage for 10 mana , (meaning you count in the 1 cost spells you make that deal 3 damage).

As to what wins me games , 60% are the Shadowcannon games , 30% are N`zoth games and the last 10% is Reno , from all the variety of Aggro decks that you do could not control out the early game .

Mulligan:

Raza against Control and MIdrange is a must keep in hand , Reno is a must keep in aggro .Of course if you have good synergies in your hand think about taking them out but Most of the times still keep them.

Deathlord is a unique Beast ,it is one of the cards that amazes to this day how it can destroy combo decks and aggro , in the mirror , velen`s +it is still a nightmare.(Coin it one 3 and then on three velen`s for best results , even zombie chow +coin velen`s is good)

Other than that  , keep sticky minions like Zombie Chow and Radiant Elemental ,when you have synergies in hand .

Shadow Visions is really really much better in this deck because you have a select few of the spells in the first place , only 8 without her, it is essential for combos and should often be use to fetch a second Pack from Elise 

Board clears: First off , for this moment , Lightbombis better than Dragonfire Potion , reason is Aggro runs higher attack lower Health , Midrange runs Higher attack and lower health or exactly 7/7, 8/8  stats, Bonemare has risen up even in the wild format so this helps with that too.

Excavated Evil is a bad Board clear , gives your opponent a card that is useful ,and helps with Fatigue, the only good matchup for it is or another Mirror which runs it ,so you deactivate their Reno and Kazakus and Raza, and still it is slow, Holy Nova is better because it keeps you ahead on board and you have many high health minions ( this is another reason Lightbomb is better than Dragonfire Potion) . The other Board clear you run is Shadow Visions , very versatile, also Kazakus`s 5 and 10 mana potions are very good , with Shadowcannon they give you a good 4 more damage. Best minion that helps with aggro is also Primordial Drake .

It is also important to bate out entombs , Priest Mirrors certainly need this to win. Against any control, unless you have fallen behind , having 2 entombs is great , so commonly pick it up from Shadow Visions .

Jade Druid :

Here`s an example of how you should have the game setup .https://m.imgur.com/gallery/Jc5h3da.

Before the screenshot ,the mulligan was a little hard , kept Reno Jackson for a case my opponent had a better than mine hand, turn one pass , after that turn two was a Golakka Crawler turn , I just topdecked it and he had a 1/1 jade , wanted to compete with the board , turn 3 was doomsayer after clearing a 2/2 jade summoned , healed up Golakka and put doomsayer , turn 4 was Kazakus into 5 cost spell , I wanted to have some damage and be able maybe to revive doomsayer , didn`t happen , got an equally good potion though , deal 5 damage and deal 4 to all , which can keep me against the next waves . Next turn I shadow visioned into Lightbomb , his 6th turn was innervate aya jade idol , i still had Kazakus on board which he did not clear , his mistake . On my sixth turn I played Lightbomb after removing Aya with Kazakus , and next turns I played some deathrattles (shredder and Sylvanas ) which he had to avoid or destroy , on 9 I already had drawn Obsidian Statue , he was gonna push jades but played safely and did not develope , (one of the many reasons that card is really wanted from stone hill <3) after that he managed to remove my board and I just N`zothed ,still have two board clears for his board mainly , and a butt load of value , keep in mind he had 10 mana 3 turns before me .Your mulligans should be for having a better board and Doomsayer and Deathlord , sticky minions.  Everyone seems to have a problem with them , playing like this should up your W/R by ...a lot

Priest Mirror - try to out value them , do not let them get the upper hand , play on curve and KEEP RAZA !!!!!! Also having the Shadowcannon first usually wins games ... Also worth noting that other Reno Highlanders actually have Shadow Spawn and deal up to 22-28 damage , with them taking 21 , this is mucho importante not to miss, always ALWAYS heal yourself if your opponent has 10 mana and their Shadowcannon , this is important because if they have Shadow Spawn and Mirage Caller plus a few other cards you are out of the game , meaning you have to be aggro and attack harder and control harder, basically that is the only way you lose .

BIg Priest - Really hard to win , you need entomb deaths and Kazakus 5 mana polymorphs ... that is it ... if they get your fast from the beginning , always keep Potion of Madness , really helps .(try to remember the names of players who play it so you are not confused  what to Mulligan .

PIrate Warrior : I am not even half joking I have not DRAWN Golakka Crawler ONCE , EVEN FREAKING ONCE , try to control the board and ALWAYS KEEP RENO !!!!!! Triggered

OTK Mages: It is easy , be a hunter SMOrc them down with the Shadowcannon , mainly you need it to start chipping away their health , you cannot forget about yours too , it is basically the Priest Mirror , so yeah winning before their combo is complete is great

Murloc Paladin: You know , turn one turn two , try to stop them from developing the board quickly and playing their Murloc War Leader , have Reno Jackson in hand , save your board Clears for the right moments , do not be greedy 

Tempo Mages: annoying , try to control the board , do not forget they have Counterspell first thing you should test after Mirror, they usually swarm the board and play Cunterspell , so going second is a charm at times , but having them play mirror image and you save your doomsayer for a board clear is also essential , they do not commit and you can draw your good answers .

Silver Paladin : You know , that Paladin , coins out Steward of Darkshire , plays Muster for Battle , Lightfused Stegodon and then Quartermaster ,Blegh , do NOT let them do that , save a Shadow Word:Pain , play something sticky and remove their board always .

Hey that sound much like ....

AGGRO SHAMAN: TBH  not that good , competitive enough for the other decks , but this one just dominates it , kinda sad really .

But always have in mind that Sneaky Bloodlust , keep Reno have Deathlord , deal with their board , develope your own and cycle through .

There are some OTK Druid decks around , mainly play Deathlord and wish to disrupt the combo , Stonhill into Rat saves games ,   But know you are really F-d if you do not push them against the wall.

There are a few players who love competitive Wild format , so keep in mind you rematches , I emphasized it on the Big Priest , it is very freaking hard to win against so BE careful.
