New player started late August, unlocked Naxx and BRM but haven't really constructed a real deck yet.. any suggestions?

Climbed decently high with a makeshift facehunter deck few days before season ended. Have been doing pretty poorly in arena.

Which class do you like the most?

You want to spend $$ for packs or mostly gold?

Mostly gold, might be willing to throw a little $$.

I like mage warlock the best, but don't care that much and happy to build into the meta

Patron Warrior. E wins Low Cost. (And requires both solo adventures) However you need to practice a trick or two and the turns you actually end the game. It will be fine just go grim patron warrior

You want a brand new player to with Patron warrior?

ya that's kind of dumb advice... smorc warrior would be possible.

@op just play w/e class you want and an archetype you are comfortable with. tempo mage, freeze mage, and mech mage require very different cards.
