Hello! This Boss became one of the most difficult encounters for me. Tried lots of different decks before visited this page.

Thanks tingozhu for sharing it. Worked perfectly good on my first attempt, though beginning of the game was really difficult mostly because of the bad starting hand. So if you're going to try this deck, keep in mind - don't give up and wait :)

Good luck!

This worked for me on my third attempt but I got extremely lucky on some draws. Good luck!

Soooo difficult to pull this off, but after about 10 games I managed to get a bazillion (4) Sorcerer's Apprentice down, along with the Oracles for lots of draw. 

Got it after 5-6 tries.

From what it appears, you need about 7 specific cards in at least 8 specific turns to make this work. Hope for a Sorcerer's Apprentice, Mad Scientist, and Echo of Medivh. Hope the scientist drops a duplicate so that you can play sorcerer's apprentice. Hope that Antonidas also drops, and hope you draw board clears until you can get one fireball, play sorcerer's apprentice, echo that, play both of them, and then get free fireballs. 

I don't know about you guys buy I'm not much for hoping for anything like that to work, and after about 10 tries, I haven't gotten close yet. I'll keep trying my own variations and wait to see if a more viable deck surfaces. Good luck, all.

Took me about 4-5 tries but I did get it with this deck. I also don't have Doomsayer and still made it work. 

ideal starting hand?

I went for card draw. Coldlight Oracle and Arcane Intellect. I dug to get Sorcerer's Apprentice. It's very hard to get the enemy to kill your Apprentice's for Duplicate, but when it happens you're well on your way. Then just Echo of Medivh to get more Sorcerer's and keep putting them on the battlefield. Echoing Coldlight Oracle as well is nice, you get a LOT of card draw, then you can finally make it to Archmage Antonidas + 4x Sorcerer's Apprentice and win the game.
