how can you obtain cards without paying?

can you farm legendary cards without paying or is the only method from farming dailies and get 100g gold packs? or doing arena?

 

disenchant cards and craft one of the dust

 

solution 1 : buy pack by paying real money and hope to get one (statistically you get one legendary every 20 pack or so) (best solution if you are loaded ^^)

solution 2 : buy pack with 100 gold and hope to get one (worst solution imo)

solution 3 : do arena, this way you can obtain pack + a chance to get additionnal dust (best solution imo)

So here are your options.

For me the best way is doing arena to stockpile dust and then being able to craft the legendaries i want.

do you create you own deck in arena or do you let it do by the bot?

 

i do it manually.
