Barnes -  Dont play barnes on turn 4, know what you have already drawn and what to expect. Usually play barnes when you have a stealth toxin or a conceal in hand, so that you can draw from auctioneer or build your questing when it comes out of barnes. Barnes can be used to fish for spell dmg too, if you havent drawn your bloodmage and drakes the whole game.

Win-condition: General win condition is to stealth your questing then put an auctioneer to rinse your deck and finish off your opponent immediately. No problem doing close to 40 dmg usually if you play it right. However, that is not the only way to win. This deck has a pretty good tempo with your 2 drops, SI:7, tomb pillager and drakes. Be careful to look out for lethal with your cold blood with the minions on board. If your minions are out of aoe range, you can cold blood->hit->conceal any minion. (I once got a mana wrym from undercity, he pinged it twice, then I cold blooded it and concealed, forcing him to flamestrike one single mana wrym)

Against priest: You can play questing if they have an empty board, but buff it into a 4/4 then stop there. You can then cold blood it to hit for the next turn then conceal it.

Against mage/shaman/aoe class: Avoid flamestrike range by buffing your questing into a 5/5 before having it concealed, know all the aoe ranges for pala/shaman in the current meta and play out of range of it.

Against warrior: Tough game. You will lose most of the games if you are fighting control warrior, 2x brawl and 2x Execute is too much to handle. Try to finish early and take risks. Always hold sap religiously and not use it if he is playing a C'thun warrior. You need to kill one twin emperor with shadow strike and sap the other for lethal.
