Not Much Better Rewards Even With Potions

I read an interesting post about the ROI on buying potions - in particular the Quest and Mystery potions for ~ 2,000 DEC vs buying a pack of cards. So i decided to try it out for myself:

Above are the rewards from the quest with an additional 5 loot chests from the potion. As you can see, it is probably a loss on this one. All hopes for this to turn a profit rests on the Mystery potion.

Hope I don't get a Goblin Mech like i did the last time i bought such a potion.

Quest

Got the Water splinter quest and it was easy as expected. A pity that i'm still stuck in Silver III so it will take some time before the number of rewards cards get to a decent level.
