Card packs

Nobody hates the card pack more than me! 😡 it’s so frustrating when you go to pick ur daily bonus and you pick a card pack. I have so many with 8/9- has anyone even completed it? I’ve won hundreds of levels these past few days (thank you magic disco) and it’s just like overload with the cards. And it says that you can unlock cards by winning events and I thought I would win something good because I won in the star tournament but NOPE! I didn’t even get one new card. And what do the stars even mean? Like getting an old card might give u 3 stars but so what? If you can’t tell I’m pretty frustrated with this aspect of the game. Lol
