This. Stack some gold, get your garunteed legendary in your first 10 packs for the year if the dragon expansions (will stay in standard longer than the others). Once the new Meta has settled after a few weeks craft the cards you're missing.

yeah thats probably a good idea. Decent of Dragons is bringing many game changing cards

You should craft a Whizbang. He'll give you a lot of, mostly bad, but fun decks.

Hello guys! The title speak for itself. Left the game when K&amp;C was released and now I'm really excited to play again. 
Recycled all my wild cards and now have 30k dust to build some decks (play standard ranked only). Should just wait until December 10th?
