I will update my winrate with this deck as long as the season goes on
This is the deck I used to reach #41 rank in the EU legend ladder
the deck is not so easy to play and focus on the combo cards 1) pint-size potion + void ripper for early board clear and 2) cabal shadow priest to steal midgame threat with pint size potion or late game threat with the acolyte.
void ripper also helps to close out the game considering how high are on health your minions
This deck destroys paladin decks (dude and murloc, thanks to the add of the combo void ripper pint-size potion to the overpowered duskbreaker), control warlock (you steal every voidlord or rin they play), beat quite always hunter and have a great play against mage (thanks to priest of the feast and duskbreaker) and is quite 45-50% against combo priest.
If you are facing more control like warrior or kingsbane rogue and more combo priests you should remove 1x mind control and 1x elise to add 2x divine spirit and play like a combo priest to finish the game with a void ripper or an operative-stolen inner fire or divine spirit.
If you are facing too many warlocks and combo priests just take off 1x potion of madness 2x power word shield and put inside the deck skulking geist to block their combos with cube or with inner fire (as I did in the end of the season)
MULLIGANZ and HOWTOPLAY GUIDE (deep search means to mulligan all the cards that are different from the chosen one )
MULLIGAN: always keep the combo Cabal Shadow Priest - Pint-Size Potion with the coin, keep Kabal Songstealer and search for Twilight Acolyte to kick his giant or to activate the cabal shadow priest later.
GUIDE: the Control version is an easy matchup: play as a combo priest in the firsts turns if you can (dragons and shadow visions) then use Cabal Shadow Priest with pint size to steal their rin or first voidlord. Then fill your hand with mind controls to steal their late game voidlords and close the game with void ripper to make them 9/3. Do not forget that you can also steal and kill their minions with the combo Pint-Size Potion Potion of Madness Void Ripper;). If they go rin and sacrifice, just slam down everything you have and try to pressure much as you can so that he cannot use his seal
The Cube version is more difficult because of doomguards and giants. to beat them you must have a twilight acolyte for their giant and you must pressure them with early priest of the feast and dragons and then steal their voidlord to spring off the last damages. The most important thing and the more difficult is to not fall too much behind.
PALADIN: pally is not a difficult matchup at all, because we have Duskbreaker Primordial Drake AND Void Ripper combo to clean their board more and more time. this is the matchup where void ripper shines and makes the difference
MULL: always keep potion of madness. shadow vision if you have the coin, northshire cleric if you are going first and deep search for void ripper and duskbreaker. do not keep pint size potion in your starting hand if you have not void ripper, you will die before you can find a void ripper, but if you find him in your starting hand it is ok to keep him because you will have 4 possibilities to find a pint size potion (the 2 cards + 2 shadow visions).
GUIDE: just try to not fall too much behind with potion of madness and your early pressure and then you should statistically have an AOE effect by turn 4 or 5 if you mulliganed in the right way. Be careful to use your AOE effects : think if you can afford to take some more damage to clean more things the turn after, but if you wait too much you will be rekt. Note that the void ripper+ pint size potion can also full clear a tarim board. It is usually better to wait a Call to Arms before using your AOE, if you can.
vs PRIEST: if he is a control we are near 50% if it is a combo a little less if he is a spiteful a little more thanks to anduin
MULL: here you should keep your early minion drop, void ripper if you have the coin and drakonid operative always. I also keep shadowreaper anduin if I have the coin and priest of the feast and twilight drake near always. it is a good idea to keep near all the dragon package to keep a great board pressure.
GUIDE: if you know he is a combo priest then you should keep the board as clear as you can, Their and also your board, because he can always steal your minions and kill you with them. So I never left my minions with more than 3-4 health after turn 7. use one void ripper combo to clean their early board full of 1/5 3/7 and so on, and slam your dragons down to keep the control of the board. here shines shadow cabal priest because you can steal their drakonid operative and twilight drake. Here anduin make a great work by giving health, removing big threats and pressuring them.
If he is a spiteful you should focus on value and keep anduin and twilight acolyte for the big beast. Remember that double pint-size potion and void ripper clear near everything.
If he is a control then you should never lose the control of the board and focus on elise and shadow visions combo to bring you advantage in th late game. do not draw with the cleric in this matchup.
MULL: deep search for duskbreaker and twilight acolyte for the big boss that comes with barnes. I also keep the dragon package and priest of the feast because you really need to pressure him if he slams down rexxar on turn 6.
GUIDE: keep duskbreaker for their wolves and pressure him with your bigger minions. also priest of the feast can help healing you if you are too low on health.
MULL: Deep search for duskbreaker and priest of the feast and always keep the void ripper if you have the coin. I also keep potion of madness if I have the coin
GUIDE: here you should be careful and take less damage you can. Then you can clean their board with your AOE effects and heal yourself with priest of the feast. If he does not draw aluneth you should be fine but it is always a good idea to put less pressure and to heal yourself every single turn you can afford it.
MULL: deep search for drakonid operative priest of the feast and twilight drake. always keep twilight acolyte to kick their vancleef
GUIDE: here is the match where you would like to have shadow word horror instead of void ripper. this is a difficult match where only the board control counts. Slam down your threat and try to keep the control of the board with potion of madness and cabal shadow priest combo. remember that he can deal up to 20 damage in a single turn with leeroy and the longer the game goes the best it will be for him.
vs dead hand WARRIOR:
GUIDE: it is our worst matchup: the only way to win is to pressure him and steal a dead man hand with drakonid operative.
