Edit buy the welcome bundle first . Everyone can buy it once . It ' s a fantastic value $ 10 , good for new players and old . I recommend buying all adventures with money , gold is best spent on cards or arena runs . Any real money you want to spend on card packs beyond that is just helpful extra cardsdust . You should be able to keep an up to date collection on a goldonly budget assuming you do your quests everyday and use cash to buy adventure expansions which tend to be cheap , $ 20 . BRM and LOE will be rotating out aka the cards still exist but they ' re segregated into Wild mode where all the old cards go , it ' s a fun place in 34 ish months . however I highly recommend purchasing at least the first wing of these two expansions before they rotate out . This is a paltry price and it ensures that the entire adventure ' s content will always be available to you if you choose to unlock the rest of it , even after the adventure rotates out . Really , if you plan to play the game for some time into the future , grabbing at least one wing of the adventures now will save you a lot of headache when your collection starts to grow later . So , you ' ve got a $ 50 budget ? You can buy almost all the currently available adventures with that . The cards in each expansion are set and many are quite good . It is a good purchase compared to packs , which are random in terms of contents . At very least the first wings of each , to make sure you can get the content later on .
