This is my plan when I get home later.
Any tips? Sounds like Majordomo is the big one for the Mirror fight.
For Heroic?
The first is the Medivh vs Malchazaar fight. They key here is using the god tier spells with your apprentices and keep them alive. Malchazaar has bad clears and as long as you keep clearing his stuff your apprentices will stay alive. Without them you will quickly go into fatigue and run out of ammo, you need that engine plus 3 cards draw every turn. Requires some luck because of you start getting stuff with no Arcane Missiles and no Spell damage then you might get rolled over.
Against Silverware Golem you want lots of granular AOE damage. I used Priest but I feel Grim Patron Warrior will be superior. Double WW, Ravaging Ghouls, Unstable Ghouls, Death's Bite, Grim Patrons etc. Hell even throw Revenge in there if you want to. I am pretty sure if you get a board full of Patrons then he's done for.
Second one is tough without Majordormo. He summon a 1/1 copy of whatever minion is played on his side including your own. Deathlord is godly in this match because you can get out a big minion really early. His deck is insane and very well synergized though he plays it like a dummy. I beat with Astral Druid after rolling a few times. Biggest problem was Mirror Entity, I would insta lose of he had it in his opening hand.
Third is just the chess piece only you can't discover chess pieces. This is not so bad until you realize you have very cards on your deck so you have to finish fast. All the special pieces you need to extract maximum value out of and use the move position option in the late game to optimize damage. Sometimes playing an extra minion means you don't get double damage on his minions so don't summon extra stuff. You want the Queen on far right after you have a lead on him so she can start dishing out face damage. I would restart the game if you lose the queen.
