Since it reads "Draw until", having even one Corrupted Blood in your deck will immediately kill you

That's a lot of draw, but fills your hand to bursting, and costs too much.  Doubt it will be used.

But thank god old Malygos is gone.

Quote from xskarma >>

Old Malygos will only be usable in Wild and Classic. New Malygos will be usable in Standard and Wild. Blizzard have already announced there will be no dust refunds for the Classic set going to Wild.

 No refund for revamps? Source?

OTKS are inherently bad design in Hearthstone as there is no opponent interactivity like in MTG and Yugioh, I'm happy for this change.

Well, Malygos OTK's were fun while they lasted. 

Well this is one way to limit Spell Damage OTK's in standard now.

This is a much better version as it can be run in any deck and is a perfect topdeck.

So this replaces old malygos? No more otk? What if we have a gold and regular copy of this card?

I don't know for sure, I'm guessing- It will hard replace them, with doubled refunds, except for Classic mode.
