You can't have Card Packs without buying them from the Hive Engine market at very high prices (or $4 each for the upcoming Chaos Legion packs) or having someone give them to you for free. 🤔 Without Card Packs, you won't have any use for the Legendary Potions or Alchemy Potions. 😐
With the amount of those Potions I have now, I would have to buy dozens of Chaos Legion Packs just to consume all those Potions. 🤔
