You guys think its possible? I tried something but my ability only goes as far as copying decks and playing it. 

Using an all Naxxcards decks isn't viable, since they don't synergize that great.
Okay, you have the deathrattle theme, but the best deathrattles aren't in the naxxset.
You have some interesting counters (like Deathlord), and some interesting "ideas" (swords).
Nonetheless you want to fill up with some basiccards to round out your deck, since naxx lacks any instant removals etc.

Still will try to troll some casual mode with it in two weeks. ;)

I'm sure Total Biscuit will stream some all Naxx decks as well.

only 22 naxx cards possible in a deck (after all wings release), even less now.

You're forgetting about duplicates.

How do you figure that?

15 non-legendary cards from boss rewards (can put two of each in a deck), 6 legendaries (one of each in a deck), one class card (2 of those).. more than enough to make a full deck. Once all wings release.

You can't do it yet, though. Once the Construct Wing is cleared, you will be able to.

 You can do it. Good luck on winning consistently. :)

Naxxramas brings us 30 cards
9 of these cards are class cards
You can only pick one class for a deck
30 - 9 + 1 = 22 cards max.

It pays dividends to read some of the posts in the thread:
