Ditto. I crafted couple wild deck: big shaman and imba quest warlock (this one rocks).
Quickly hit legend 3k with warlock.

There are ofc more viable wild decks, like kings bane rogue, but i didnt try them out, though i saw them showing good results.

As for standart - for returning players they offer free standart decks. I took warrior. And it is pretty good for standart to move close to diamond.
