Here is another quest which I am going to open is it worth to get the card but if you get above the burn value it will be fine.
Not bad to get lots of cards and I think after some card we need to burn them.
I don't think fighting a lot and get a quest reward these potion will be meaning full and they are not worthy until you buy the packs in the future.
you need a lot of money to buy pack officially to get some good cards which are mostly promo cards and they remain costly entirely in the season of new series as well after that too.
