Got one from a Drakkinshard booster pack as a loot card..not sure if it is now a random from any set of booster packs or not, but can confirm it was Ping's Practical Potion pack that was the reward ( 5 Potion of adventure, 10 x Potion of Harvest..10 x Potion of Healing). Good luck !!!
This item come's from LoN car game -- when open'd it has 5 potion of Divinity -- 5 potion of Adventure -- 10 potion of healing and 10 potion of harve I dont think it's a bad item -- have seen worst from LON
