Thank you so much for the wonderful answer guys! this is why i love hearthpwn community when you ask a question the answer would be quick and very detailed i'll stick to grinding golds and opening card pack hoping to get the cards that i needed for a deck, I'm currently using Odd Rogue and Spellstone hunter

as the title says, I didn't played that much this season due to my collection.... 

 The time I enjoyed that game the most was when I started ! 

I had nothing and I was trying to build some 100% custom decks out of cheap cards because I was missing 70% of cards of every meta deck:P

Yes, it was totally unfair, but the pleasure I had every time I managed to outvalue and beat a tier 1 deck (full of booms,rag beltchers and owls!) was irreplacable!

..and now that I can play every single deck, I play hearthstone for less than 2 hours per week

Best way to grind gold is arena and i've found help watching top arena players that explain their choices.  Also hsreplay.net shows the tier list for standard, wild and arena so it can help when deciding classes to choose from.  pay attention to synergies but don't be a slave to them when there is a better "value" card to choose.  a lot of arena pros state how useful the 2 cost minions can be since you might not always get your 1 cost minion to start things off but a 2 cost minion is usually solid for more turns.

Learn when to commit different cards instead of going all in like alot of standard games go.

It's all about having the answer to the board and keeping ahead of your opponent.

 solid post, thanks
