If you want to finish Nozdormu the Eternal quest by actually winning the game, then you better pick the character which you hate most! (or at least i do) Which is :

The freaking mage!

Why?

Because for obvious reasons
Mages are known by their massive spells and their abilities to draw more cards and eventually outplaying the enemy if they survive long enough to get to the endgame so that they could spam limitless spells when they have alot of mana (like 8-10)

If you are having a Nozdormu The Eternal Quest, You might as well as having all sorts of Dragons with you because Nozdormu is a dragon but a single dragon is useless and if you want to win the game you must pick as much combination of a sort as possible so in this case we're going to pick as much dragon as we possible can!

Check out how cool they are i.e if oyu happen to get this card going on your battleground it will just like the FIRE LORD card, attack 9 damages (firelord does only 8) and the good part of it is that you don't lose any hp because it will DEAL 9 damage, it is not going to ATTACK, so it will use a ranged ability to hit the enemy or their minions (even if they have a divine shielded taunt minion, or lets say arbitrary 7 of them on the battleground, you can still win the game by hitting the enemy hero, though it is only 1/8 chance)

Can you imagine having them on your hand at the 9th turn??
I really like the Nozdormu Card because if both of you have it, you and your opponent, then what will happen is: turns will finish in 15 secs, which is boom you put a card, your opponent puts a card, there is no time to think, so that's why i put all these dragons as they are very powerful and there is a chance that your opponent have the nozdormu too, so having low cost cards won't help you and you need really high cost and effective cards to finish and beat your opponent in this small 15 secs timeframe

Imagine if your hand was empty and you for some luck reached this card and used it and you are a mage!!!!!! KABOOOOOM game over. The amount of spells you will get at the 10th round will easily finish the game by doing at least 10-20 dmg and it is alot when you consider the fact that the heroes has 30 healths...

You won

AND If you happen to heal yourself or decrease the enemy's hp

Here is some help,

Admit it, it is cool and useful BECAUSE you can heal 8 health to your hero and survive 1 more round (or two) or you can deal 8 dmg to the enemy hero or any of their minions (again if he has a taunt minion, you can jump over the taunt minion which you normally can't with a flat attack card)
