Whilst Warrior is easily the toughest class to get 9 wins with, Mage choice of cards seems designed purely to be bumfunning you. 

Like a bad day going through international Customs. 

nb - this is based purely on my experience of international travel and dungeon runs. And at least after sticking 2 un-lubricated hands up your back passage the dungeon run allows you to try again. With no prejudice. 

I have just finally won mage using a full hero power deck with ring of justicar and stealth to my minions, try it out it just steamrolled the dungeon :P

Mage was by far my toughest as well. I had 90 boss kills before my first completion. Either I got bad draws on treasure's/decks or I would have an amazing deck that steamrolled everything, then I would run into Azari and he would eat all of my good cards. I finally ended up winning by fatigue against the Shadow with a kinda amalgamation of a deck, but it had Arcane Giants and Frost lich Jaina.

Every other class gets to 7 wins easily.  Mage is just so bad and you're lucky to win 4/5 before running into a wall/boss that was made to counter every single thing Mage can do.  It's the only class I haven't beaten Dungeon Runs with and I'm about to give up

If you know the right combos it could make the run easier

Here is a list of combos I used to win this run:

Cloack of invisibility and magical armour is good every hit doing one hit is pretty useful and magical armour can't be hit by minions so it should help on almost every boss.

Exodia mage is what I used to beat king toggle woggle just bring magic mirror and copy your sorcerers apprentice. Usually you want to pick magical friends when you can with cloack of invisibility.
