You know that ONE GOD FORSAKEN CLASS you don't own those FEW cards for that make up a good chunk of the decks you can find on here or any other site

me? DRUID

God I hate getting quests for druid because I don't have Force of Nature, Tree of Life, Ysera, and Cenarius

not to mention i've seen Aviana pick up in popularity

Priest, rogue and shaman, simply because I don't play them

Warlock fo' sho.

Maybe Rogue as well.

Druid and Priest, in no particular order. 

I do not lack the cards, but the playstyle of these two classes I simply can't wrap my minds around. 

Rogue because i don't have Preparation

Rogue...Rogue..and Hunter.... do not like the playstyle of those types.... Priest used to be.. but with the new dragon decks now this class as at least the ways to dominate the game... before it was just about reacting what your opponent did

those FEW cards for that make up a good chunk of the decks you can find on here or any other site

For me trying to make a good deck, while having a limited card pool is the best challenge and experience in TCGs. Try not to net deck, try to be creative to make a decent deck with what you have, try an unusual archetype.

Of course, it's much easier and quicker to net deck, but you are missing a major part of TCG experience then.

Definitely Rogue. I still can't figured out how to play her. I only have record of 20 win games with her. When my other class have over 100 wins/golden portrait.

Rogue, although it can be quite a challenge should I take it, with positive overall experience. I just can do only oil rogue with no preparations, and the playstyle of a rogue is kinda "too tricky", and oil deck is too dam unreliable.

Shaman and Rogue.

Formerly Warlock and Priest.

Shaman, Rogue and Warlock because i don't play them. 

well i play 5 classes so there's fairly low chance that i end up with quests that don't roll to my favor

I'm missing 'key' cards for all of the classes but the ones I am most likely to reroll are Warrior because I don't even have a Warrior deck.  With only 9 deck slots, 8 of mine are taken up by 'class' decks and the last slot is for experiments or adventure mode decks.  I had to give up one class back when I decided to work on Naxx heroic (a lot harder when you have a small card collection) and picked Warrior since it felt the least fun for me to play.

I also don't really like Mage much but I have a Mage deck specifically for the Spell quest that has almost all spells in it.  I don't expect to get wins with it and the goal is to just live long enough to cast as many spells as possible to get the quest over with.

The classes I am most likely to try to finish 'win' quests with are Hunter (beast), Shaman, Paladin, Warlock and sometimes Druid.  I consider my Druid deck to be terrible but it's kind of fun to play and it wins more than I think it should.  It is mainly my 'big minion quest' deck and just has a ton of cards that cost 5 or more (unfortunately it is missing the Ancients, Force of Nature and one Druid of the Claw to make it a 'real' Druid deck).

NONE, I play ever class.

Every one .

I don't like being told what to play for some gold .

I just wanna play my best decks and win as much as possible. 

Murlocs, regardless of the class

Shaman and Priest.  Because I've got gold heroes for both Shaman and Priest. 

I reroll anything that isn't Hunter or Priest. For the last season I've played only two decks. I want to build something new for this season so that I don't have to reroll quite so often. 

Druid. I have never enjoyed a deck from this class. Ramp and Jade both were not fun for me. The egg Druid seems interesting, however I don't have living mana yet.

Rogue. I have no quest, no Auctioneers, no Leroy, no Patches, no Aya. I have no interest in the class and there's just no way to make a cheap, competitive deck without any of those cards.
